I'm hoping someone on the list has some expertise that they could share with me. I've searched the list archives but didn't turn up anything. I'm working with some thick sections (about 1 mm) embedded in Spurr's low viscosity epoxy resin. The goal is to incubate these sections with fluorescently labelled nucleic acid probes. The first thing I plan to do is try incubating these with a Polysciences epoxy removal kit to make the cells accessible for staining. I'm wondering if anyone has experience with using nucleic acid probes on thin sections, or could direct me to some good references. Is there anything I could use to increase the permeability of the epoxy, or are my probes just going to bind to whatever is exposed with the epoxy removal solution? Also, could anyone recommend a way to fix the sections on coverslips for manipulation in the staining procedure and later viewing with epifluorescence?
Here's one for the "never a dull moment" category. I have occasionally used the freeze-drying effect of our FESEM's cryostage to sublime ice off of LN2 plunge-frozen samples. Now I have someone who would like to try this with liquids such as benzene and other solvents. I'm willing to give it a shot, but have no clue how such liquids behave at low temperatures. Our client says the solvents will freeze at the temperatures we operate our stage at, but she also has no idea whether "freeze drying" will occur with them.
Has anyone tried this? As usual, I'll be checking the literature, but personal experiences are always the most useful, and I figure you folks have collectively done it all at some point.
Thanks for all the help----past, present, and future.
Cheers, Randy

I assume that in checking the literature you will be determining the temperature and pressure at which each organic will sublime and the possibility of contaminating the chamber and other lower parts of the column. I assume that you are using an anticontaminator around/above the specimen holder; have you every lost control of the temperature or otherwise have the specimen "warm" up to room temp under the beam? Working with frozen organic solvents is something that I would contact your SEM manufacturer about and get their input.
I also wonder why you are getting ice on your samples. Are you using a device and method of avoiding ice contamination? Do you use LN2 slush? Having worked also with liquid helium 4 to freeze biological specimens, ice contamination was not an option so it can be done.

Question: We recently purchased a Nikon digital camera for optical microscopes as well as Image Pro image analysis software.
We have abandoned use of Image Pro software because of contant problems. Does anyone have recommendations for comparable image analysis software packages?

What kind of problems? Is there some kind of processing or measurement you need that is not provided, or is the software crashing, or do you just not understand how to use it? Image Pro Plus is a widely used and generally rather powerful package. Certainly there are others, including ones that are "comparable." But they may present "comparable" problems for your application, too.

Could you advise me on the best primary fixative to use for marine species that need both light microscopy and TEM? Currently we are fixing our specimens in 2.5%Glut/Form in cacodylate buffer and bisecting the animal -half for em and half for light microscopy. We perform histology on the LM half first, then if we need to retrieve the em fixed tissue we have the ability. In an effort to reduce work load and tissue storage do you have other suggestions?

Randy, Have a look at http://www.sisweb.com/referenc/applnote/app-84.htm
I found this application note related to your follow-up question while looking for a new mist filter for our mechanical pump. It seems that normal oil mist filters are only effective at trapping the high molecular weight hydrocarbons from pump oil.

Dear Listers,
Here's one for the "never a dull moment" category. I have occasionally used the freeze-drying effect of our FESEM's cryostage to sublime ice off of LN2 plunge-frozen samples. Now I have someone who would like to try this with liquids such as benzene and other solvents. I'm willing to give it a shot, but have no clue how such liquids behave at low temperatures. Our client says the solvents will freeze at the temperatures we operate our stage at, but she also has no idea whether "freeze drying" will occur with them.
Has anyone tried this? As usual, I'll be checking the literature, but personal experiences are always the most useful, and I figure you folks have collectively done it all at some point.
Thanks for all the help----past, present, and future.

What type of problems are you experiencing with Image Pro? We've been using IPP for the past eight years without much incident. Is it technical problems with the hardware/software, or is it a matter of training? Perhaps you're not aware of the new forum they provide to discuss issues and applications of their software. The URL for the forum is:
http://www.mediacy.com/ipp/ippforum/
This is an excellent source of information about the software that you can utilize before just tossing the several thousand dollars spent on it! Feel free to ask me off line and I'll see if I can help you also.

Question: We recently purchased a Nikon digital camera for optical microscopes as well as Image Pro image analysis software.
We have abandoned use of Image Pro software because of contant problems. Does anyone have recommendations for comparable image analysis software packages?
Your question is very broad. Are you unhappy with the results you are getting? If so, exactly what is wrong? And which "marine species" are you working with? Have you checked the literature on the species of interest to see what others are using and what kind of results they are getting? I think you will have to provide more information if you want a specific recommnedation.

We are considering buying a digital camera for imaging a wide range of subjects (isn't everyone!) though our first project is centered on chlamydomonas fluorescence work particularly chloroplast auto-fluorescence.
So far the optronics microfire looks like a good camera that might suit our needs and I would very much appreciate any comments on this camera from anyone who has had experience with one.
Many thanks in advance

With LM, I would like to look at starch granules from the topside and bottomside of a slide, in order to get more information about shape.
I can do this by flipping the slide over, and raising it slightly off the platten so that the coverslip is not scraped off - but to relocate the same object on the slide might require a lot of searching.
Can anyone suggest a simple mathematical formula that can be used to calculate new co-ordinates from (a) the linear dimensions of the slide (L x W), and (b) the mm grid co-ordinates of the object on the slide?
Does a formula/conversion-table already exist for this?

In principle it is real simple x(new) = Length of slide - x(original) y should remain the same if the slide is perfectly rectangular and the geometry of the stage is perfect. You will need to correct for any discrepancy between zero on the stage scale and the end of the slide (x=0).

In our group (polymer physics) a long time ago, freeze drying of para-xylene (m.p. 19°C, b.p. ~ 144°C) was used. There are quite a few organic solvents freezing around 0°C, and many of them should respond to this technique. What is important is the vapour pressure, so things with too high a b.p. wouldn't work.
However, as the other replies state, it's the pumping system one should worry about.

IPP is a powerful application and of course depending on the version you are using, it may have some limitations (by features that you may not able to program for yourself). However IPP is as powerful as the user can use it. There are other applications out there and one application that is not driven by programming ability is MetaMorph by a company that used to be called Universal Imaging, recently it has been under a company called Molecular Devices. Check it out but don't give up on IPP so easily.
Ciao! Nico.

Question: We recently purchased a Nikon digital camera for optical microscopes as well as Image Pro image analysis software.
We have abandoned use of Image Pro software because of contant problems. Does anyone have recommendations for comparable image analysis software packages?
Thanks to everyone who replied to my question about purchasing flatbed scanner to scan TEM negatives. Most of you suggested EPSON and Canon scanners. So we will go with one with a reasonable price tag.
Best wishes,
Soumitra

I would consider the Zeiss AxioVision 4.0 software. Accurate, very user-friendly and with quite a lot of basic functions that can be even more expanded. Wizards and record-functions help you to automate repetitive analysis... I have no personal benefit if you would start using this software, don't get me wrong, it just 'dazzled' me with a few things in such a way that I even bought the VBA-module to start programming in Visual Basic to even more expand it's possibilities! Besides this, a very helpful forum has been created to exchange questions, answers, programs etc., just as this forum. Best,

Hi everyone, In my experience, DAPI very specifically stains DNA nicely. I have also used other DNA stains like Sytox but I get better definition in DNA/nuclear labeling with DAPI when taking epifluorescent micrographs.
For what concentration of DAPI to use in your specimen, I would recommend a PubMed search.
I hope this helps.
With much sincerity, Carlo

I concur with you Greg, I personally prefer the old method. However, the change was made about a month ago as we were getting far too many inadvertent postings and the rash that occurred at the end of July was getting just too much, particularly with the almost immediate followup of an apology.
For the time being, just a reminder to all subscribers. Please remember (and this is documented in the Instructions if you are replying to a posting and consider the information of general use to everyone, remember to change the reply to address from the senders address (automatically provided by your Email client) to include
microscopy-at-microscopy.com
It is also appropriate should an individual collects a series of answers /solutions to their question that (s)he compose a summary of the responses and post that back to the list. This way it will be included in the archives and provide a convenient mechanism for others to locate a synopsis of the question and answers using the search engine

Title-Subject: [Filtered] en-bloc stains for light microscopy
Question: Hello there,
I was just wondering if anyone had ever happened upon a reliable method for en-bloc staining insect neural tissue in araldite embedded specimens.
I have tried a few things so far, including, toluidine blue, ferricyanide and p-phenylaminediamine. While these seem to help none of them give satisfactory contrast without post-staining the sections with tol. blue.
Does anyone know of something that will stain membrane structure well and can be used en-bloc? The specimens do not have to be embedded in araldite embedded...just something that will cut 1-2 um sections.
Dear Isha, Well, as a plant biologist, I have to say that *all* parts of the plant are interesting! But perhaps it is worth mentioning that root tips may be easier to fix and prep than other parts because they lack cuticles, air spaces, and wood, all of which can give rise to sample prep issues. Of course, all of these other parts can be preped too so follow your own curiosity.

The usual en bloc stains used for TEM work probably won't give you enough contrast for LM unless you try phase contrast or Nomarski illumination. p-phenylenediamine will reduce the osmium in the tissue and increase contrast but is not a stain in the usual sense. If you used ferricyanide-osmium and en bloc staining with uranyl acetate you might get enough contrast for your needs. Only you can make that judgement. Toluidine blue is leached out of tissue very rapidly in the ascending ethanols used for dehydration. Try Cresyl Violet or Thionin instead OR dehydrate in acetone instead of alcohols. I don't think either will show up (much) in the EM though.

I understand that a true plant biologist such as Tobias would find all plant tissues of interest. However, I started out as an animal person so love lots of "stuff" in my images.
Many plant cells have huge internal vacuoles and relatively few organelles so can be very uninteresting to many people. However, if you start out with very young tissue, such as the very young leaves from a bean plant, than you will find lots of interesting stuff.
In this case, the leaves will be so thin that you will be able to prepare and microtome x-sections through the entire leaf. You will see the different cell types and arrangements toward both the top and bottom leaf portions. You will also get lots of chloroplasts, nuclei, a fair number of mitochondria and other organelles. You should be able to find golgi, etc. If you are lucky you will cut through stomata as well.
This can be lots of fun as well as informative. Good luck!
I would recommend a half strength Karnovsky fixative in Cacodylate buffer followed by osmium and possibly en block uranyl acetate staining. You might need something to control the osmolarity such as NaCl. Check the literature for details. Embedding should be in Spurr resin or other low viscosity resin as plant walls can be difficult to infiltrate. Use a very gradual infiltration, increasing resin concentration very slowly with gentle rotation/agitation until you have reached 50% resin and then can go a bit faster.

Nestor, Is there any way to make 'Reply All' include the listserver address along with the correspondent's address?
It will be interesting to see if mis-addressed replies increase on the other microscopy-related listservers that retain the old reply mechanism.

I need to clarify my fixation question. First, I am trying to fix marine amphipods for both light and TEM. Currently I am fixing them in 2.5% Gluteraldehyde and 2.5% Formaldehyde in sodium cacodylate buffer and bisecting the animal and placing half in 70% EtOH for light microscopy and the other half in cacodylic buffer. I then process the animals for light and if the pathologist sees anything interesting I will have the other half of the animal fixed for any em work. I am not doing any immuno.
The fixation is fine, but is there a less labor intensive way? I don't like storing my tissue in the buffer because it molds after about 8 months.
I appreciate all of your questions and I look forward to your comments.

I am writing to invite you to attend a day long symposium on advanced biomedical imaging techniques. The venue for this is the annual Research and Industrial Collaboration Conference (RICC) sponsored by CenSSIS and held at Northeastern University in Boston. The RICC is a two day affair (October 6‑7). The biomedical imaging symposium will take place on Friday, October 7th (Day Two of the RICC). The morning session of the symposium will discuss stem cell imaging and will include speakers such as Gerald Schatten (a member of the team that reported the recent canine cloning in South Korea). The afternoon will focus upon techniques for multi spectral cellular imaging and will include speakers from both academia and industry.
A complete agenda listing, directions and registration form can be found on the web link: {http://www.censsis.neu.edu/RICC/2005} http://www.censsis.neu.edu/RICC/2005.
A more general description of the CenSSIS research and education programs can be found on our homepage: {http://www.censsis.neu.edu/} http://www.censsis.neu.edu.
In addition to the presentations at the symposium, there will be an opportunity to learn about the 3D Keck Fusion Microscope (3DFM) facility which is located at Northeastern. The Keck 3DFM is a multi-modal microscope capable of imaging live samples in up to six different modes for at least 72 hours. Along with standard DIC and epifluorescence modes, we are imaging with single and two photon fluorescent excitation wavelengths from 454nm up to 1100nm. We also have a newly patented, noninvasive, and nontoxic imaging mode called Quadrature Microscopy. This specialized technique measures the phase change of light as it passes through a live specimen and yields comprehensive real time data. A link to the full description of the facility can be found on the CenSSIS homepage.
I hope that you will be able to attend our symposium. Don't hesitate to contact me if you need further information. The registration deadline is Sunday, October 1st.
**Important Note: All unused rooms will be released from the hotel room blocks on September 14, 2005. Please be sure to make your reservation as soon as possible. Room price and availability cannot be guaranteed beyond these dates.
Best,

Dear MSA members and other listers, As wrangler of the MSA video collection I am often asked if we have a full basic course in electron microscopy available on DVD. We do not. I can also infer from folks who purchase 20 or 30 or 40 or 50 DVDs that they intend to teach themselves what they need to know from our recorded tutorials. (The record purchase is 52 DVDs that was filled last month.). In light of the fact that EM coures are disappearing at universities around the country, the Education Committee of MSA is considering the idea of putting together a basic course or courses on electron microscopy and make them available on DVD. Something that would present the technology in an organized fashion and be comprehensive enough to put a student in a position to begin work in the area. If such a project is undertaken, Steve Barlow and Howard Berg have agreed to work with me on coordinating it. First, we would like to hear from the community on whether or not they think this is a good idea. Second we would be looking for volunteers who might be willing to record a lesson with supporting demonstrations and other visual representations that could flesh out the coverage. We don't want just a talking head. We would also be looking for folks who would be willing to share the syllabi from their courses so that we might determine how to go about organizing such a thing. Any and all feedback is welcome.

Greg- Yea! I was on of those who purchased your DVD's and yes, I would love to have a DVD with the basic course. It would be great if you could improve the DVD quality, the info was great, the visual could be better. Good Idea! I hope you get a lot of response from the EM community.

Hi, I'm researching SEM instruments and am wondering about yearly service contracts and how they change over the life of the instrument. Thoughts? Thanks, Ann.

I think that that would be a great idea. However, I have another suggestion to add to it. I would like to see the original lesson broadcast over the internet where MSA members could "tune-in" to watch. Perhaps there could be a question and answer period from audience memebers that wold be included int he video also. Afterall, many of the original tapes were recorded at the meetings.

I can't answer about graphite paint, but I am still using the same bottle of colloidal silver after 10 years. I'm a TEM (AFM,XRD,FIB...) man really so I only use it to mount samples for SEM once in a while. Even if it's completely dried out I find that adding a bit of the relevant solvent (4-Metyl-pentan-2-one, usually) and a buzz in an ultrasonic bath for an hour makes it as good as new. So I would call the shelf life "unlimited". The main problem is getting the damn lid off the bottle..

I would say much the same as Richard Beanland but about carbon paint. We have had jars sitting from a large order sitting on the shelf for years. They have always been fine when I open a new one.
Our big problem is getting users to put the caps back on tightly. A couple times a month I go around our lab and check the opened bottles and add propanol to bring them back to the original consistency. Time in the sonic batch would probably help, but it will just dry out again. I usually give it a good shake, let it sit for a while and shake it again. Even with that, I usually rarely get a chance to through a bottle away because it's empty. Usually, I find one that has dried out too much before I get to it and figure it is not worth the hassle to try to rejuvenate it.

A question for the list: I am looking for some (cheap/easy to use) 3D reconstruction software to make 3D models from CT slices. I'm not looking for anything to fancy. I'm looking at CT data from extant crab claws and need to model an internal structure that is more dense, and show it in relation to the exterior of the claw. The two programs I have looked at are Surfdriver (now only for PC) and VGStudio Max. Does anyone have any other software options I should be looking at? I'm hoping the software would work on the Mac, but if I had to I could find a PC. Many thanks in advance. -David -- David A.

Depending on the sophistication of the reconstruction you need, you should check out ImageJ, which is available free at: http://rsb.info.nih.gov/ij/. The program is written in Java, and will run on virtually any platform.

OK people. I've tried to send this twice already, and had some problems which do not appear evident to me. But will try again.
I would like to try and get a thread going on the subject of reduced osmium fixation. Not so much on the ‘what I’ve used’ form as the ‘what is the difference, what is the value, what is the mechanism’ form. Some hypothetical, perhaps our more chemically inclined can provide some factual information on chemical reactions, and some ‘what protocols exist’ form. Gee, I guess that last point does get into the what 'I’ve used' form, doesn’t it. OK, include the 'what I've used'.
The source of interest which has given rise to this is a question a student asked the other day. This person had ferrocyanide (Fe4+) and wanted to know if it were possible to use it in place of ferricyanide (Fe3+). Since my procedure called for ferricyanide, and I had some, I gave it to them and they went away happy. At least I think they were happy, I never can really tell about students. Then there was the listing from Richard Berry in Australia, and Geoff McAuliff's response which also raised Osmium-ferricyanide.
Unfortunately, this has all started me thinking - always a dangerous thing. So, I checked my copy of Hayat’s Fixation for Electron Microscopy [sorry Phil, some of us do have it ;-)]. The results were quite interesting.
Hayat mentioned procedures for both ferri- and ferrocyanide. Went to his original references, read those i could get my hands on readily (our library has taken to storing some older issues of journals). I won’t get into a long re-hash of what is there. Briefly: 1.) The original hypothesis by Elbers was that fixation with ferricyanide/lead as a step between glut and osmium, could help stabilize phospholipids. Subsequently it was used to stabilize surfactants. Maybe stabilize surfactants - there is mixed data on that. The key seemed to be the presence of the Pb, not the Fe. 2.) There was a ferricyanide report that used 1.6% ferricyanide, 1% Osmium. Note, this is 2x the concentration of ferricyanide I use now. Hayat didn't really say what the advantage was supposed to be, though.. 3.) Karnovsky’s report to the 11th (or 14th) meeting of the Am Soc. for Cell Biology in 1970, and the Russell & Burguet work from 1977 were discussed, but the roles in membrane fixation, or mechanism, for that matter, were not. This is also covered in Bozzolo and Russell under membrane fixation. 4.) de Bruijn and Den Breejen’s work (1975) which showed no difference in ferricyanide and ferrocyanide reduced Os in terms of subsequent staining of glycogen was referenced, but not discussed.
Next, I checked the catalogues to see what the EM suppliers made available. That's always a good indicator as to what people are using. Some suppliers had ferricyanide, some didn't. And i found none with ferrocyanide. Some of our regular suppliers of non EM lab supplies, chemicals, etc, do sell both, and as 10% solutions, which makes using it real easy!!!
So, for the thread. Is there a difference between ferri- and ferrocyanide. If there are any differences, why? Is the operative agent iron, as a reducer of osmium from VIII to VI, or is it a mordant effect of the cyanide moieties - as suggested by some? What concentration of ferri/ferrocyanide should we use, 0.8%, 1.5%, or even 2.5% as recommeded by Russell and Burguet?
Today, my only thought is that K4Fe(CN)6 would reduce the Os from octavalent to hexavalent more quickly than K3Fe(CN)6, but I doubt it would make a practical difference in the fixative.
Any takers on seeing if we can educate ourselves on this. Get a good, profitable discussion on line?

We are looking into the possibility of replacing our film cameras with Imaging Plates. I am aware of the Fuji and Ditabis systems. Are there any other systems available? (vendors welcome to respond!)
I would also appreciate any feedback concerning the use of the IP systems, both concerning the particular vendor/system and IP units in general. It is probably best to keep the feedback off-line. I can summarize to the list later.

One thing that seems to help prolong the usability of carbon paint is to shake the bottle *after* you're through using it. This helps wash the semi-dried material at the neck back into solution, so you don't get as much dried up gunk in the neck of the bottle after repeated use. This is especially true if the cap has a brush built in, and you use the edge of the bottle to slurp off the excess before applying to stubs. Just make sure the bottle is tightly closed (speaking from experience).

An impressive mold, growing in an arsenical compound. I suspect there is no less labor intensive method. I certainly never found an easier method when I was doing amphipods. The best way to store the EM specimens is to go ahead and process and embed them. Once they're in plastic, they'll last for years. With no mold. The good fixation is more important than less labor.

A colleague, who is experiencing specimen damage in the TEM, inquired if anyone knew the temperature generated on the specimen by the electron beam. I realize that there are a lot of variables here, but even a range of temperatures would be useful.
Here are his operating parameters:
kV = 100 spot size = 2 micrometer (specimen was examined at approximately 2 micrometer spot size) specimen = ceramic containing metal particles (Ti) magnification = 100K to 600K electron gun = LaB6 vacuum = turbo pumped to 10-5 Pa substrate that specimen was mounted on = Formvar/carbon coated grid

At steady state, the heat in, which is the stopping power, dE/dx, in units of joules/meter times the electron beam current times the specimen thickness, must equal the sum of conduction (assume a disk at one temperature surrounded by an infinite amount of the material at ambient temperature, plug in the conductivity, the temperature difference, and the area across which the heat is conducted, which is the circumference of the beam spot times the thickness of the specimen) and radiation, which is equal to T^4 (on the Kelvin scale) times the area of the beam times the Stephan-Boltzman constant. The stopping power can be set equal to the sum of stopping powers for each element in the specimen times their fractions. The effect of the grid can probably be ignored (unless the illuminated part of the specimen is over a grid bar, which would greatly increase heat conduction). The parameters necessary to do the calculation are the stopping powers, the heat conductivity, and the geometry of the specimen. Then one can set heat in = heat out and solve for the temperature for which the equation holds.

This gives an upper limit to the heat deposited in the specimen, since not all the energy loss is converted to heat. Some is carried away by bremsstrahlung, secondary electrons, etc.

.....If it is a stain related issue, you may want to try embedding in LR White methylmethacrylate resin. This resin is quite different from epoxy resins in that you can use a acid fuchsin/methylene blue stain to produce an H&E like stained section...
I have used (successfully) another "H & E"-like stain with epon. My reference is an application note (303) from LKB: "Stains for Plastic Embedded Tissue Sections II. Staining of sections from different animal, human and plant tissues with a methylene blue-azure II-basic fuchsin stain" (Humphrey) - Maj Andersson (April 1977).
The original reference was: Humphrey, CD and Pittman, FE (1974) "A simple methylen blue-azure II-basic fuchsin stain for epoxy-embedded tissue sections" Stain Technology. 49; 9-14.
It gives beautiful results.

Phay Fang Gan wrote: =============================================== Question: May I know the shelf life of the conductive silver paint and carbon paint ? =============================================== This seemingly simple question has a complicated answer.
First, despite "conventional wisdom", the silver paint used in EM labs is not "all the same". In addition to the obvious difference in silver solids between products, and variations in silver colloid size, some paints (including the SPI Supplies brands of silver paints) contain a small amount of an "amyloid" polymer, not enough to affect negatively its conductivity, but enough to greatly enhance its adhesive characteristics.
But this is not the only function of the presence of the amyloid polymer: If one should forget to screw on the cap to their silver paint bottle, the addition of the recommended thinner and a few minutes in a laboratory ultrasonic shaker will quickly "rejuvenated" it and bring it back to life. But those silver paints without the amyloid polymer or perhaps some other polymer that is not so readily dissolved will either be rejuvenated much more slowly or as we have seen, in some cases, not at all.
So if you are using at least certain silver paints, since the life time of the silver colloid is essentially infinite, and solvent that evaporates can be replaced with the right thinner (even to the point of its having dried out into a brick), there is no real lifetime limit. There are legal and other reasons why manufacturers might publish some "expiration" date for such products but from a practical stand point, at least for some brands of silver paint, the life time is essentially infinite.
But if your question had to do more with the lifetime of the silver paint product unopened, and sitting on the shelf, then this has more to do with the closure system, including the heat seal. Again, not all closure systems are the same. I have seen some silver paint products on the shelf of certain distributors in foreign countries where the paint was as it was delivered ten or more years prior. And I have also seen paints of other brands that had dried out into bricks after only a few years on the shelf.
When discussing the shelf lives of carbon paints, you could almost substitute "carbon" for "silver" above (except that for those carbon paints that do contain a polymer, it is not (to my knowledge an amyloid type). The shelf life of at least some carbon paints is indeed just as infinite as their silver paint counterparts.
Rather than commenting further on where the SPI Supplies brand family of silver and carbon paints fits into this picture, I would refer anyone interested to our silver and carbon paints "main page" at URL www.2spi.com/catalog/spec_prep/cond_paints.html and then draw your own conclusions.
Disclaimer: SPI Supplies is a major supplier worldwide of the SPI Supplies® and Dotite® brands of silver paint and SPI-Chem brand of carbon paint products used in electron microscopy and surface analysis applications.

Liberty Science Center in Liberty State Park, Jersey City, NJ, has a lightly used 1982 Zeiss 940A SEM available immediately. This scope was serviced yearly until 2000 and used little after that up to about 6 months ago. Both vacuum pumps and chiller are working but the SEM needs some work to get operational again.
Anyone interested in this microscope, please contact Betty Faber, bfaber-at-lsc.org.

I can comment on the carbon paint. I use a bottle until it's totally gone and I can't get any more carbon in solution using isopropanol. I should say I use SPI's conductive carbon paint because it cleans up easily and can use isopropanol as the diluent (even though Dr. Garber would recommend I use their thinner instead). I've been using my current bottle for about 5 years now for SEM and FIB work. When it gets to the consistency of chocolate pudding, I add a couple of mls of alcohol and shake for around 5-10 minutes. As others have recommended, definitely keep the lid on tight and shake well before and after use.

The temperature in the sample due to the energy being deposited in it is very dependent on the thickness of the sample. At 120 keV, if I did not deposit a sufficient layer of carbon on glass cross sections, the glass would soften under the beam. 100 keV would be worse. When I used a 200 keV machine, the problem essentially went away. For 100 keV, to avoid the problem, the illuminated area must be very thin.
One of the other things that I did that seemed to help with glass samples was to use a piece of Si as the mate to the cross section in the stack. The Si seems to take more of the heat away from the sample. Either that or it supplied a temperature insensitive portion of the total sample to prevent the sagging.

I don't have the answer to this question but when I was renovating my TEM I was playing around with a sample of actinolite asbestos. When we increased the power of the beam we easily melted the fibres. Theese were thick fibres, don't think any of them were electron transparent so the maximum amount of energy was absorbed by the specimen. If my memory doesn't fail me we used 100kV and no apertures. As the TEM wasn't fully operational I have no idea of the size of the fibres.

I think Bill Tivol's outline of specimen heating is fine, and a very worthwhile exercise. One of the consequences of the T^4 power for radiated heat is that you don't get much heat loss by radiation below about 200C (lots of hand waving and caveats here, this is a very rough number). However I'd like to add to the emphasis on the importance of a good heat sink. I know from experience that I can fry a lift-out FIB section of InP on a holey carbon grid in a 120 kV TEM (melting point 1060C, but starts to decompose around 550C). Not very enjoyable if you just spent a few hundred £ getting the damn thing made. On the other hand I never have any problems with conventionally ion milled specimens, which have 20um thick InP on a Cu grid on the outside, tapering to the hole in the middle, and even materials like PbSn solders (melting point 183C) and Au/Ge multilayers (interdiffusion {100C) are fine if there is a good thermal path to the support grid. From your description of the sample I guess it's a lift-out FIB section. As others have pointed out, higher kV will help since the beam-specimen interaction is less. Or you'll have no problems with a H-bar section, which has a massive heat sink all around the thin area (but you won't be able to do meaningful X-ray analysis). Or you may have to go back to the old ways of making specimens..

A colleague, who is experiencing specimen damage in the TEM, inquired if anyone knew the temperature generated on the specimen by the electron beam. I realize that there are a lot of variables here, but even a range of temperatures would be useful.
Here are his operating parameters:
kV = 100 spot size = 2 micrometer (specimen was examined at approximately 2 micrometer spot size) specimen = ceramic containing metal particles (Ti) magnification = 100K to 600K electron gun = LaB6 vacuum = turbo pumped to 10-5 Pa substrate that specimen was mounted on = Formvar/carbon coated grid

Question: I have recently carried out some EDX analysis on a Ga-Au alloy for which I would like to a have rough idea of composition. The analysis was made for an object which is about 40 nm thick with a STEM probe in a FEG 200 kV instrument. Since the Au K signals come at too high energy for our detector, my question is if it is possible to compare the K-shell band of Ga with the L-shell band of Au. Or would it be more correct to do that analysis comparing the two L-shell bands of Ga and Au?
Since all the Au-Ga compounds are known, all you need is a rough value of composition to say which one it is. I usually take a diffraction pattern or two and compare measured d-values with the international crystallographic database if there's any uncertainty. You may have to do low angle convergent beam (using a tiny condenser aperture) rather than selected area diffraction if the grains are small in a multi-phase compound. The nice thing about TEM is that you can get EDX and diffraction analysis from the same grain. As for the EDX analysis, using different lines (K,L,M..) shouldn't be a problem anyway - if you had to do a proper job, you would be comparing it with a known standard and you can use whichever lines you like as long as there's no strong overlaps (I'm happy to be corrected on this by people who do this every day, I'm no expert)..

you should use Ga-Ka and Au-La because of the comparable excitation and absorption conditions with energy of 9..10 keV. This is the best choice, even if your detector would be able to detect Au-K. But take into mind for (only rough) concentration determinations, if the Ga/Au- concentration ratio is expected with 1/1, then the peak-heights or pak-net counts are like about 6/10.

I really like the DVD idea...I don't do as much microscopy as I used to and I'm getting rusty! Or maybe I have that disease, you all know the one I mean, CRS...Can't Remember Stuff! A little help is always welcome and DVDs would be good 'cause you could pull them out when you had a specific question or problem. I think this is a great idea.

Dear MSA members and other listers, As wrangler of the MSA video collection I am often asked if we have a full basic course in electron microscopy available on DVD. We do not. I can also infer from folks who purchase 20 or 30 or 40 or 50 DVDs that they intend to teach themselves what they need to know from our recorded tutorials. (The record purchase is 52 DVDs that was filled last month.). In light of the fact that EM coures are disappearing at universities around the country, the Education Committee of MSA is considering the idea of putting together a basic course or courses on electron microscopy and make them available on DVD. Something that would present the technology in an organized fashion and be comprehensive enough to put a student in a position to begin work in the area. If such a project is undertaken, Steve Barlow and Howard Berg have agreed to work with me on coordinating it. First, we would like to hear from the community on whether or not they think this is a good idea. Second we would be looking for volunteers who might be willing to record a lesson with supporting demonstrations and other visual representations that could flesh out the coverage. We don't want just a talking head. We would also be looking for folks who would be willing to share the syllabi from their courses so that we might determine how to go about organizing such a thing. Any and all feedback is welcome.
Regarsd to all, Greg

for years i've been able to do the stats on my immunogold quite easily. unfortunately i have a project which requires dealing with odd shaped granules and inclusions in cells, and labeling on the membranes vs not on the membranes. i'm afraid i'm going to have to come into the computer age here, finally.
i would appreciate the advice of the list on simple programs which will allow me to use a stylus to draw around the perimeter of the region in the micrograph which needs to be analysed, and then give me the total area within the region identified. don't need any more analysis. i can still count the black spots - the eyes haven't gone yet.

...or you could use one of the available image processing tools to do exactly what you want. Here is a link to our website (http://www.soft-imaging.com/rd/english/433.htm, click on the "gold labelling" line on the right side), but there are other programs out there that do this.

One of our TEM service reps told me that he's been told that many people who looks at polymers in the TEM "pre-burn" their samples under a UV lamp before putting the grids in the column - is this true? If so, how is it done (for how long, distance from bulb, etc.)?
We have a weird "thing" with our TEM that burns a pattern into resin sections and we were discussing ways to pre-burn; chemical stetching doesn't help, and doing it in the column is too slow when there are a lot of samples. If I could do a mass burn I'd be set!
Thanks!

Just about any program out there - including NIH Image which is free - will do that. But why in the world would you NOT want the program to do the counting, too? Lots of tests have demonstrated that people don't really count things very well. And even if you CAN do it accurately, you certainly can't do it as quickly as the computer.

I have ImagePro and MetaMorph and the ImageTool Kit and have used them all successfully. But I disagree with John that using a computer is always easier and better. Maybe if I had written the book on image processing like John Russ, I could take my TEM digital images and have the computer automatically threshold, detect and count the colloidal gold particles against a typical cell background in a reasonable amount of time. Despite being modestly familiar with the morphometric software packages, I often still find it easier and faster to count small amounts of gold particles by eye. I use a program like Photoshop to place a colored dot on top of each gold particle as i click it. My experience is that i can do a lot of images fast and not have to worry about losing gold particles touching black membranes or something that screws up my thresholding detection in a random set of real world images. I can always tweak the thresholding for a single image but often find the next image needs a tad more tweaking. I guess if I was a lot better at image processing or my samples were more idealized, I would agree with John's comment but most people aren't as good as he is so I think there is a place for those of us who count by eye.

I have followed this discussion with some interest because a similar situation prevails in cathodoluminescence (CL) instrumentation, including those used on optical microscopes (10 to 20 kV, 0-1 mA electron beam).
The beam current is obviously an important variable since the total power is the product of beam voltage and beam current. This can be as much as 10 watts or more in the CL instruments (15 kV and 0.7 mA typical operating condition). One of the questions that comes up immediately is the measurement of the beam current. I am not familiar with the methods of electron microscopy but in CL microscopy often the beam current "displayed" is the total current from the high voltage supply, usually measured in the ground return line. The actual current to the specimen can be significantly less than this because a portion of the beam is intercepted on various anode apertures, collimators, etc., depending on the particular instrument design.
It is possible to measure the current to the specimen if it is set up with a suitable Faraday cup arrangement to suppress secondary electrons but this is rarely done.
Sample temperature discussions often go back to Carslaw and Jaeger, 1959, Conduction of Heat in Solids (general solution for a point source on a semi-infinite solid) and Castaing, R. 1952 (Thesis - Application des sondes electronique a une methode d'analyse ponctuelle chimique et cristallographique.). Castaing's solution is appropriate to electron probe conditions.
With the geological thin sections that are the usual subject for optical CL, the lateral thermal conductivity of the section is often a big question mark also. Tight, well-cemented, samples have relatively high thermal conductivity. But there are examples of quartz sandstones with high porosity where the individual quartz grains in the thin section do not make contact with adjacent grains - only with the epoxy imbedding media. I have seen situations where an individual grain is so well thermally isolated by the epoxy that it would glow brightly with cathodoluminescence and then become "red hot" to the unaided eye while adjacent grains would appear undisturbed..

With regard to the image analysis problem in hand (TEM and 'black' gold particles), ImageJ (or NIHImage in its Apple variant) is probably the best way to go as it is a powerful image analysis program and free to use. It is a little complicated in its user interface though (not that MetaMorph is actually much better in this respect for the extra £3000). For a stylus input (cell tracing) and a photo holding pad you need to get one of those Wacom Graphire pads for £80 or so (www.wacom.com). I have to say I and many others never got on with the Wacom stylus/pad I bought, but other users in the department seem to love them. I am happier with the mouse. The Graphire tablets work on the Apple and PC, integrate into programs (and also have a mouse).
Find ImageJ (PC) at http://rsb.info.nih.gov/ij/ and NIH Image (Apple) at http://rsb.info.nih.gov/nih-image/. As mentioned PhotoShop can trace round images to give pixel area - but ImageJ is a proper image analysis program and would be useful in other projects. Electron micrographs are often tricky to threshold , so tracing is probably quicker (although try size parameters to remove the larger detected objects, and total area / mean individual object area). When using ImageJ have a good look at all the plug-ins (I download and install any that seem even vaguely interesting). The basic package can do the area measurements and grain counts once calibrated (Analyze, Set Scale) and thresholded. ImageJ also has a selection of image processing commands (but a duff image remains a duff image afterwards).
If you have a had a bit of luck on the gee gee's, try Image Pro whose home is http://www.mediacy.com/ and MetaMorph at http://www.universal-imaging.com/. These programs are pretty slick for most applications, and have lots of extra's like cell motility tracking, but MetaMorph in particular is idiosyncratic and difficult to get to grips with for the casual user (but its mostly all in there somewhere). Useful image processing applications like deconvolution are extra (a lot extra). They are both expensive basic packages as well. OpenLabs at http://www.improvision.com is also OK for this sort of thing, and is Apple based, but its better at image capture and time-lapse as its image analysis component is relatively poor (although their Velocity package is a great 3D reconstruction program at £10,000).
I have been using image analysers since the 1970's Quantimet 720 and I have to say that generally it is often easier to count by eye rather than use the image analyser. This is particularly true for things I count like fibres (complex counting rules) and alpha track stars (that have tracks that vary in number, length and thickness). However if you have hundreds of very bright or very black dots on the image that can be distinguished easily by thresholding then obviously the image analysis program can count them easily. Plus if you are counting hundreds of grains within a sample if doesn't really matter if the image analyser counts 950 and you count 980 - both counts are probably well within biological variation. Just pick the quickest way to count (often by the time you have processed an image for automatic counting often you could have counted two images by eye, particularly if there aren't that many objects). Modern programs should have a manual count option anyway - click on the screen and the object is ticked off, numbered and counted. Also do make yourself a help file document of how you did something with an image analysis package, as its often difficult to remember how you did it a few months on (PrtSC to copy and paste the program menu VDU view is useful).
Older dedicated hardware based image analysers like the UK Magiscan Colour and the Seescan systems were often faster than modern multi-tasking PC versions and included things like real-time binary image editors and light pens (and they never seemed to crash). They also seemed to be more tuned into scientific research needs (e.g. their separate detected object algorithms worked far better in 1989 than those in Metamorph, ImagePro or OpenLabs do now). With any image analysis its the quality of the sample and captured image that is paramount, so its worth spending time on sample preparation and setting up the microscope (e.g. for DIC). Uneven 'illumination' and a poor specimen is a disaster in light microscopy (and EM) image analysis, although background correction can help in light microscopy. Trying to recover information from a poor specimen by image analysis techniques is not the way to go.

No generally not, there are dynamical diffraction effects in electron diffraction that affect the intensity of spots. This includes double diffraction effects that can allow some classes of forbidden reflections (those forbidden by glide planes and screw axis) to occur. There are innumerable other factors that make the intensities different as well.
Use the d-spacings and forget the intensities.
In order to index electron diffraction patterns it really help to have a complete list of all d-spacings and corresponding symmetrically-equivalent hkls for a given material. Such a list needs to be calculated from the cell parameters using appropriate software. I use some home-grown software to do this. I don't know if there is any commercially available software on the market right now that will do it. (Listserver folks help if you know...)
Calcium carbonate has the R3barC space group and will have dynamically allowed and dynamically forbidden reflections depending on whether you calculate the d-spacing based on the primitive rhomobohedral or center hexagonal cell.
Hope this helps.

"The statements and opinions expressed here by Gary M. Brown represent neither those of ExxonMobil Corporation nor its affiliates."
Tamara,
Ultrathin sections of oriented polymers (stained or unstained) often deform when first exposed to the beam. This relaxation can be achieved prior to analysis by low-dose exposure to the electron beam for several minutes at low magnification. The objective is to relax the sections and make them physically stable during microscopy. I prefer not to use this procedure because it can cause significant deformation of the sections.
A better procedure, in my opinion, is to mount the sections on high quality continuous carbon film grids. Do not use Formvar or Formvar/carbon films since Formvar films are not very clean and can cause problems during imaging and elemental analysis. The sections adhere to the carbon film and will not deform under the beam, thus eliminating artifacts relaxation and/or orientation in images. Image quality is still very good. One must still be careful about beam damage, since this is still a real possibility, carbon film or not.
Hope this helps,

One of our TEM service reps told me that he's been told that many people who looks at polymers in the TEM "pre-burn" their samples under a UV lamp before putting the grids in the column - is this true? If so, how is it done (for how long, distance from bulb, etc.)?
We have a weird "thing" with our TEM that burns a pattern into resin sections and we were discussing ways to pre-burn; chemical stetching doesn't help, and doing it in the column is too slow when there are a lot of samples. If I could do a mass burn I'd be set!
Thanks!

There is a new add-in for the analySIS software that does pretty much exactly what you want. It identifies the gold particles not only by their grey level, but also by their "roundness" and expected diameters. You can also analyze double-labeled samples, etc. I don't want to make this too commercial here, so please contact me via email. I am also looking for beta-testers of the software. If you (or anybody else) is interested, please contact me.

I have thought about your inquiry for several hours and waited for anybody to respond . Gary Brown´s advice makes sense.
UV lamp produces oxygen radicals and therefore attacks carbon compounds as a preferred chemical reaction partner. Using a UV-lamp is very slow and results, depend on distance to the source and radiant heat.
Nevertheless, I recommend a plasma treatment before analysis. This could possibly mean cleaning, surface modification and conditioning in one step. Hopefully, you do have a plasma instrument in your lab to test. Try air or bottled oxygen for a start.

-------------------------------------------------------- -------------------- The Microscopy ListServer -- CoSponsor: The Microscopy Society of America
One of our TEM service reps told me that he's been told that many people who looks at polymers in the TEM "pre-burn" their samples under a UV lamp before putting the grids in the column - is this true? If so, how is it done (for how long, distance from bulb, etc.)?
We have a weird "thing" with our TEM that burns a pattern into resin sections and we were discussing ways to pre-burn; chemical stetching doesn't help, and doing it in the column is too slow when there are a lot of samples. If I could do a mass burn I'd be set!
Thanks!

Question: I work in the Electron Microscopy area of the histology department.I would appreciate a procedure for liver biopsies. I am using the new ERL-4221,Cycloaliphatic Epoxide Resin from EMS.The thick and thin sections look hazy and cloudy. I wondered if it could be the resin.Do you use it in the same proportions as the old VCD?
Dear Damien (and others who replied to this question),
Thanks for your kind advice.
I expect the double cover-slip procedure will be needed. However for the repeated handling of many samples, it would be good if there was some kind of holder system that made the coverslips easy to handle.
I will probably put the coverslips in a cardboard sandwich with holes.
If it was of interest to many people, perhaps a holder like this could be mass-produced at low cost, with covered strips of adhesive ready-to-go.
Best regards, Peter

} Peter, } } I'm not sure that this is going to work very well if you are talking about a } specimen on a regular microscope slide with a standard cover slip. One } reason is that the slide is much thicker and you may not have sufficient } working distance at higher magnifications unless you are using extra long } working distance lenses. I don't know of any such ELWD oil immersion lenses } for higher magnification work. Furthermore you may not be able to obtain } Koehler illumination. } } The effect of the thicker microscope slide glass on the image is another } issue. I would suggest that you prepare your sample between two large cover } slips in whatever mounting media you are using and tack them together with } either clear tape or a thin coating of clear finger nail polish, or other } adhesive. Then you should be able to flip them over and not worry about one } slipping away from the other and if you are using water, they will not dry } out as quickly. } } Damian Neuberger, Ph.D. } Consultant } Microscopy/Digital Imaging/Image Analysis } 2416 Covert Rd } Glenview IL 60025 } Tel: (847) 998-8574 } email: neuberger1234-at-comcast.net {mailto:neuberger1234-at-comcast.net}

The intensity in electron diffraction are subject tro many parameters such as doubble diffraction , thisckness of the specimen. So they very often do not match those reported in the JCPDS data base. To indexe you should only consider the position of the reflexions. A programm like "CaRine Crystallography" may help you to do that

If you don't use digital images, you can also use a transparent paper that you place on top of your micrograph. You draw the area you're interested in, you cut it out with cisors and you weight it with a precision scale. After determination of your weight-to-surface factor (just weight a 1 cm2 piece of the same paper), you don't need any computer to determine the surface. It's easy and acurate (and fast).
Re "adhesive strips". Somewhere in the deep dark recesses of my memory, I recall that someone manufactured something that would form a strip of adhesive on a slide onto which a cover slip would be laid. Sort of a transfer system. I think it had to do with cell culture work and created a tiny chamber.

FOCUS ON MICROSCOPY 2006, Perth, Australia, April 9-12, 2006 19th International Conference on 3D Image Processing in Microscopy 18th International Conference on Confocal Microscopy
Dear Colleagues
After the successful FOM2005 conference held in Jena in March this year, it is a pleasure to announce that the next conference: Focus on Microscopy 2006 will take place in Perth, Western Australia, April 9-12, 2006. As the next in a series of unique interdisciplinary meetings on advanced multidimensional light microscopy and image processing, the conference will be hosted by the University of Western Australia in Perth. The conference will be located at the beautiful Esplanade Hotel in the historic waterfront suburb of Perth, Fremantle. Focus on Microscopy 2006 is the continuation of a successful conference series presenting the latest innovations in optical microscopy and its applications in biology, medicine, material science, and information storage. 3D optical imaging and related theory are important subjects for the conference. The series is as relevant now as at any time in its history as the scientific and engineering communities strive to meet the needs of a surging life sciences sector, as well as respond to the sustained pressure for miniaturization in lithography and data storage. The conference series is known for covering the rapid development of advanced fluorescence labelling techniques for the confocal and multi-photon 3D imaging of -live- biological specimens. This year, in addition, special attention will be given to imaging in thick tissues and the use of laser light as an active tool at sub-micrometer length scales for cell biology, nanobiotechnology, and medicine.
Abstracts for contributions are invited and can already be submitted through the website: www.FocusOnMicroscopy.org where further information on the present and previous FOM conferences can be found.
Important dates: Deadline for the submission of abstracts: January 9, 2006 Acceptance of contributions, draft program: January 23, 2006 Deadline for early registration: February 20, 2006
We would be very pleased to welcome you to Perth for the FOM2006 conference and exhibition.
On behalf of the organising committee,

Have you considered a "screen capture" system that will take the video and store the image? It just may be cheaper. The one caveat about this approach is that you may need to cut into the appropriate points in the video drive circuit since many older microscopes do not bring these points out to a connector. My experience was with a Hitachi S570 and it was a little messy but it did work. My need was to do EDX mapping so the video capture was an integral part of the x-ray system.

Hello Everyone,
We're thinking of replacing the polaroid model 545 4x5 film holder in = our Hitachi S-800 SEM with a camera that will allow us to take digital = images instead. Does anyone have any suggestions for models that will = fit our microscope?
Thanks,

From nearly 40 years of working with electron and x-ray diffraction patterns, plus several years of membership in the JCPDS, now ICDD, I can offer a rule of thumb regarding intensity of ediff vs. x-ray diffraction data: Strong reflections are strong reflections and weak are weak. One cannot make an identification of an unknown phase using ediff ring data where very strong x-ray lines are missing from one's pattern, without giving crystal-chemical reasons to account for the missing reflections. Likewise, a 5% intensity x-ray line will not suddenly become a 100% intensity ediff ring-pattern reflection.
Electron diffraction patterns will SOMETIMES have extra and structure factor forbidden spots (& rings, as appropriate) due to double diffraction and relaxation of structure factor rules due to specimen thickness effects with thin TEM specimens, etc. --Emphasis on "sometimes."-- With regard to solving for unknown phases using ediff data, the extra spots/rings, when present, are either a help or a hindrance as they are most conspicuously present at large d-values, which are the most diagnostic d-values for phase identification. In the rare instances where I had a true unknown specimen in the TEM, and I thought I had a match with a phase in the ICDD x-ray data base, except for the presence of weak, large d-spacing reflections in the ediff data, I could sometimes confirm my identification by computing forbidden (100), (110), etc. reflections and matching them to my experimental data. Should an image of your specimen show it to be loaded with twins or other features that cause extra reflections, you should make appropriate forbidden reflection calculations early-on.
The ICDD has products to aid electron diffractionists. The Max-d/Alphabetical Index (now called the Long-d index, I think), and products derived from the Sandia database come to mind. Check www.icdd.com.
Fairland: the answer to your question is "Yes, probably."

Hi there, We're setting up a vintage instrument, a Cambridge S-250 with a vintage microspec WD spectrometer.
This spectrometer needs P10, which is to be expected, but also P90. Praxair don't know what this is, logic dictates that its the inverse composition of P10 i.e. 90% methane 10% argon. Do anyone have a similar instrument and knowledge of this gas ? Thanks, Skage
What do other universities, etc. charge for using a Laser Capture Microdissection System? We are starting to have outside users on the system.

Question: If anyone has experience with the old Nikon Fluophot, is it possible to remove/replace the epi-fluorescence filters in the turret or were they glued in place?
Skage, Yes, P-90 is 90% methane and 10% argon (and is flammable). Sounds like you've got a thin window detector running at low absolute pressure for light elements. That setup needs a lot of quenching gas (methane) and not much ionizing gas (argon) to work well.

I kind of assumed that anyone using a TEM photo or negative would scan it into a PC at hi-res and then use digital zoom [if necessary] with a stylus+tablet or mouse within the image analysis program to draw round the digitised image (I've bonded with my PC and mouse). I have just had a discussion with Tobias (Baskin) of the University of Massachusetts Biology Department, and he mentioned how he finds it a bit quicker using a tablet mouse with a crosshair to accurately trace round and digitise the photomicrograph's or photocopy's features. I notice that Wacom (www.wacom.co.uk) have a (CAD) crosshair mouse with their Intuos 2 (A4 oversize) tablets and GTCO CalComp make even flasher tablet devices, e.g. the Drawing board III, for a comparable price (Tobias successfully uses a CalComp tablet) - see http://www.gtcocalcomp.com/files/BROdb3small.pdf .
I liked the trace, cut out and weigh idea. It certainly works Ok (if you don't have 500 objects to measure per image). I have also known less numerate colleagues using string to measure perimeter (even for circles). Conversely I have used an epidiascope to capture a graph and a £100k image analyser to measure the area under the curve (then FigP came along in the 1980's).

The question is primarily aimed at the Biological TEM crowd.
Has anyone experimented with using a Heat block unit for curing plastic instead of an oven?
The reasoning is that a heat block fits in the hood more easily and can be moved out when not in use. The hood space here is extremely limited and the oven typically has been curing Spurr's and Epon type Resins in the prep room, a practice I am not comfortable with (and neither are the Safety folks here).
Looking at the specifications for the Dry Heat Blocks some are +/- 2ºC stability wise in the $200 range with the fanciest models having +/- 0.5ºC range stability.
Yes I am aware of the limitations, specifically sample number, no it wouldn't work for constant routine samples where there's a constant flux, but for individual processes where no more than one or two groups of samples are cured at a time it would seem reasonable.
Thoughts? Experiences? Conjecture? Opinions?
Thanks, Geoff Williams Facility Manager Leduc Bioimaging Facility Brown University
I have never done it but suspect it would work. maybe even better than an oven. Sus Ito, one of the great early TEM guys, once told me how he use to drive from Woods Hole back to Harvard in Boston and he would tape his tissue samples in liquid resin to his engine block so that he could section them upon his arrival! I just wonder how you write the Materials and Methods description of that up!

Take a look at D100. Also consider the 105/2.8 AF-D micro Nikkor and the SB-29s macro speedlight.

I apologise for stating the obvious, but have you thought about purchasing a more compact oven from one of the e.m. suppliers. These would at least be capable of holding flat embedding moulds as well as capsules at a uniform temperature.
We purchased one with external dimensions of 400mm x 330mm x 300mm although there was a more compact version of 335mm x 305mm x 230mm in the UK.
I certainly agree with your concerns about polymerising Spurrs/any epoxides resins in the lab. I stopped doing it over 20 years ago. One other possibility would be to find a well vented outhouse/shed if your safety people would be happier with that.

The Nikon D70 has most (all?) of the features of the D100 (and some additional ones?) at a less-than-$1000 price tag. I've had good experience using it for macro photography, combined with the 60mm macro lens (with an effective focal length of about 85mm) and a Nikon SB600 strobe. The 105mm macro lens (with an effective focal length of about 150mm) will give more working distance, but is a bit harder to hand-hold (this may not be a problem if you put it on a stand). --Jan Factor

The D-50 is a good choice with the 60mm Micro Nikkor f2.8. I have the D2X and same lens for close up macrophotography of flowers and other plant parts for the Chicago Botanic Garden and it is superb but the raw files are 70MB per image! What ever camera you buy, be sure that it can take raw images. Also, if you decide to buy a fixed lens camera, be sure that it is the kind that has a LCD viewfinder in addition to the LCD screen in the back of the camera. For close up photography, you want to see what the lens sees and the LCD on the back of the camera is often hard to see in room light (and outdoors); you can buy hoods but that's another item.
However, there is another issue and that will be lighting. Using photo flood lamps, halogen or other "always on" illumination produce a lot of heat and specimens can quickly dry out and the heat can get to you in a room. Been there done that! One choice for the Nikon is two SB800 flash units mounted on a bracket on either side of the lens. That should give you auto exposure. Another option (and perhaps better) is the ring flash but Nikon's is not auto exposure (yet) but Sigma Photo makes one that is supposed to be auto with the Nikon digital cameras but you should contact Sigma http://www.sigmaphoto.com/flashes/flashes_flashes_details.asp?id=3258 to discuss.
I don't know how close you will have to get to photograph those tumors but if you will have to be inches from the specimen, the auto flash will become a problem in that you may have to start using ND filters. Another option might be to use the 105 mm Micro Nikkor which will give you a little more working distance but it costs more.
Disclaimer: Nikon is only my preference but other manufacturers make equally suitable cameras.

You ask a question which is actually quite interesting, and applicable on a number of levels. First, of course, is would a block work. I will assume you mean something like the sand blocks we use in the other (one of my 2 non-EM homes) lab. As you note, there would be limitations, but the temperature control on all sand blocks I’ve ever worked with is a lot better than any oven I’ve used. You just have to take the time to set the temperature. As Tom Phillips noted, there are plenty of examples of alternative systems for providing the polymerization temperatures, so to join the chorus, I see no reason why not. And as far as using the car engine, I even remember a book about cooking while you drive which came out in the 70's, engine block potroast and all.
The interesting part of the question as I see it is: why would you want to put the block into a hood. Do you mean a fume hood, so you could use the block for an intermediate step in infiltration, with low temperature heating to assist in driving off transitional solvents? If so, it is an interesting idea, one worth some thought. Could be quite useful.
Alternatively, do you mean a laminar flow hood for containment at a BSL-2 level or higher. This is the most interesting potential application. Those of us who work with emerging diseases groups, or with infectious pathogens at the BSL-3 or BSL-4 levels are confronted with a number of safety issues that this concept could address. Some of my collaborators work at higher levels. They fix with a modification of Karnovsky’s fix (we use 2% paraform/2%glut in cacodylate). But their safety people will not let them take the material out of containment for further processing until the samples have been in the fixative for 30 days. I feel this may lead to some deterioration of the samples, and that there is no evidence that the pathogens are not inactivated in hours, and so do not like this. But safety people will not let them do otherwise.
There are too many other things to do these days for me to give up 4-6 hour blocks to go work in containment, so I’m not too keen on taking spacesuit training - it would be fun and really interesting, but there is just not enough time. Your question raises a lot of ideas which can address the problems of processing, permit good technique in processing, and meet the demands on the biosafety level.

The macro lenses work best with the macro ring flash SB-29s. It costs about the same as two regular speed lights. However, its big advantage is adjustable power and adjustable shades over the flash lamps.

The reason Geoff wants to put the heat block into the hood is probably the same reason why I would never polymerize resin outside the hood: fumes released during this process must be extremely toxic. And as far as finding a very small oven that would easily fit into a hood, this is not so easy. We bought the smallest we could find, but it is still more than 1 foot wide and deep, which takes too much room. We in fact have been using a second, smaller oven, that is really just a box fitted on top of a hot plate! It is very similar in design to the heat block Geoff wants to use. The temperature inside is very constant, the only drawback being that you need to calibrate the temperature control button. This only has to be done once. I think the idea of using heat blocks is very elegant, and I don't see why it shouldn't work with Eppendorf tubes or even Beem capsules. For flat embedding in moulds however I don't see how you would manage it.
Good thread, Geoff. My guess is that if nobody has tried this before, you should give it a shot and report to the list how it went!

When our current was being designed, I specified one bench with an awning hood to vent fumes from solvent dishes, paraffin baths and embedding ovens. The 30" deep bench has a 3" gap between the backsplash and wall. The ovens are beneath the bench and their fumes are pulled up behind the backsplash. The stainless steel awning is 28" above the bench with a plexiglas skirt extending 4" below the awning to increase face flow.
A heat block is likely much cheaper than remodeling one's lab.

It appears to me that the problem to be solved is to find a way to polymerize resin but protect staff personnel from the fumes that are given off during heating yet find a space-saving solution.
A simple approach would be to only use sealed molds such as Eppendorf tubes and BEEM capsules. The oven can thus be placed anywhere in the lab. However, I do know that many people prefer the ease and lower cost of re-useable flat molds.
I have been experimenting with polymerizing resins using a microwave oven. With variable results. However, with some formulations of resin it is possible to polymerize in a flat mold in less than 2hr.
I have used a laboratory-grade microwave connected to an exhaust duct (which is very convenient) and also with a regular kitchen microwave. The end result is, if the resin is going to polymerize, the process will work in either machine.
Not all resin recipes work and even fewer of them can be polymerized in a flat mold. It may be worth giving this approach a try.
The best part of sing the microwave is that the exhaust duct allows us to place the machine far from the chemical extractor hoods. Connecting a regular oven to an exhaust duct may also be a reasonably effective solution. Our convection oven has a wide duct in the top to which metal ducting, similar to that connected to household clothes dryers, can be connected.

Hi all I am wondering reading these e-mails, does anyone really know how noxious the fumes are that are released from an embedding oven? We too are pressed for space in the hood so I've moved the embedding oven into a not heavily populated corner in a large lab. We polymerize LR White and epoxy resin blocks-5-10 blocks worth maybe once a week at most. I can't smell any fumes in there ( unlike the mercaptoethanol or ETT the molecular biologists regularly use). Am I exposing a room full of people to something bad? Is it the quantity of blocks that one needs to worry about? The microwave is great for processing (hooked up to the fume hood via the duct) but I don't ant to baby sit it for 2 hours to get a perfectly hardened epoxy flat block.

Yes, you can use stereo pairs to calculate a surface profile and from there calculate roughness parameters. We have a module for our analySIS software that accomplishes this. If you want more information, please contact me by email.
There are certain limitations to what you can do with this technique. The z-resolution depends on a number of factors, the most important of which is the tilt angle. For typical tilt angles of 6 - 10 degrees, the resolution is roughly 1/10th of the lateral resolution (you can calculate that by multiplying the lateral resolution with the tan of the stereo angle). For example: If your stereo images have a resolution of 1 micron (1mm x 1mm field of view and an image resolution of 1000 x 1000 pixels), your z-resolution will be on the order of 10 microns. In order to evaluate if the technique will do what you want, you need the following information: required field of view, image resolution, stereo angle.
Let me know if you need further info.

I don't know of any free stuff. The least expensive is probably the Fovea Pro software from Reindeer (www.ReindeerGraphics.com), which has a demo version you can download that both fuses stereo pairs and performs a variety of surface roughness measurements. Several other companies offer routines that derive elevation from stereo pairs, but few also perform roughness measurements. The most versatile, complete and probably accurate program I've seen is the Alicona package (www.alicona.com), which has a demo version you can download. But it's a long way from free.

Mike Bode described a way of estimating the vertical resolution that can be achieved by using stereo pairs. His trigonometric calculation predicts that the practical vertical resolution is 10x worse than the lateral resolution, for tilt angles of 6-10 degrees. I wonder whether users of various SEM measurement tools have the same experience in actual practice. And I wonder what the observed limits of vertical resolution are for the highest resolution FE-SEMs. regards, Don Chernoff ================================== Advanced Surface Microscopy, Inc.

Could anyone recomend a microscope for silicon inspection? I don't have more than about $900 for this project. I found this forum by searching in google for IC decapping information.
I'd like the microscope provide better images than these: http://media.diywelder.com/images3/091205-MMILogo_IMGP2051.jpg http://media.diywelder.com/images3/091205-RightOfMap_IMGP2068.jpg http://media.diywelder.com/images3/091205-wholechip_IMGP2074.jpg
Those were taken with an old zeiss microscope at UAA (university of alaska anchorage). Its a triocular microscope with CCD camera, but I captured those images looking through the eyepiece with an economy pentax digital camera.
I want to get crystal clear images of the silicon. Here is a 20 mega pixel example of what I can get by holding my digital camera to the eyepiece. Its fuzzy on the right because I had to "aim" at an angle into the eyepiece to avoid strange hazing. Warning...2mb JPEG
Although not free (costs about £5000), the MeX software developed by Alicona (see www.alicona.com ) is an excellent way to derive roughness measurements (and lots more) using SEM. You can use stereo pairs, but the new Tricreator uses three images tilted relative to each for greater accuracy (which can't be achieved by reading the tilt angle from a specimen stage). --------------------------------------------------- Gary Nichols, Material Sciences, Pharmaceutical R&D (D435), Pfizer Global R&D, Ramsgate Road, Sandwich, Kent CT13 9NJ, UK e-mail: gary.nichols-at-pfizer.com tel: +44 (0)1304 643925 fax: +44 (0)1304 656726

Question: Please be very wary of venting the oven curing the resin blocks anywhere other than in the fume hood. We have one lab Tech who is unable to work with em resins at all due to extreme sensitization several years ago. Recently, one worker decided to cure some resin blocks in another lab in an oven outside of the fume hood; within hours her eyes had swelled so badly that she could not see. She was only working in the vicinity, but in a big, well ventilated open plan lab area. Once senstization has occurred, it is always potentially very serious, for anyone exposed to the fumes and not necessarily technical staff working in EM. Incidentally, resin dust makes my fingers swell within minutes of handling/sawing small blocks, even wearing gloves,so I avoid this practice now. Hope my comments help.
Hello Everyone, As the list members have been so helpful in past, I try my luck again.
I have an old Jeol JSM-6400, which were accidentally vented close to one of the pirani gages. I suspect this action damaged the pirani gage as the relevant valve wont open even if the attached penning gage records a good vacuum in the chamber in question. Anyone had similar expiriences ? and most importantly do anyone have electrical schematics for a Jeol JSM-6400 ?
Hello Geoff We were faced with the same type of space limitation in our hood. What we've done is vented our oven to the fumehood's duct via the thermometer hole (we removed the thermometer adaptor which left a 3" hole) on the top using 4" diameter metal ductwork. There is a damper control in the line allowing us to adjust the rate of exhaust. Voila! No new hood needed, more room in the hood, no potentially noxious fumes in the lab. FYI the vapours from curing epoxies are noxious, and can cause susceptible people to develop mucous membrane irritations and swelling.

The question is primarily aimed at the Biological TEM crowd.
Has anyone experimented with using a Heat block unit for curing plastic instead of an oven?
The reasoning is that a heat block fits in the hood more easily and can be moved out when not in use. The hood space here is extremely limited and the oven typically has been curing Spurr's and Epon type Resins in the prep room, a practice I am not comfortable with (and neither are the Safety folks here).
Looking at the specifications for the Dry Heat Blocks some are +/- 2ºC stability wise in the $200 range with the fanciest models having +/- 0.5ºC range stability.
Yes I am aware of the limitations, specifically sample number, no it wouldn't work for constant routine samples where there's a constant flux, but for individual processes where no more than one or two groups of samples are cured at a time it would seem reasonable.
Thoughts? Experiences? Conjecture? Opinions?
Thanks, Geoff Williams Facility Manager Leduc Bioimaging Facility Brown University
Venting the oven to the current hood was the first consideration. We do have a very nice oven, it works well. But there is little to no counter space near the hood and to tie the oven exhaust into the existing hood in the lab would first require a Facilities Management Feasibility study, and more than likely a few thousand dollars in modification, mostly because it has to be certified to draw a specific amount of air and also to not affect the functioning of the rest of the hood.
I didn't realize that Ladd sold a dry heat curing device when I wrote the email. However, not to put a price tag on anything, I want to try either one of the economical units on the market or ideally borrow one from a lab for the trial run.
And sealed capsules are not vapor free. For a brief idea on the toxicity of the chemicals in any of the most common epoxy/resins read the warnings on the bottles. It is how I always started the lab portion in TEM when we got to mixing the Spurr's. Nothing like getting the attention of students by talking about central nervous system toxins.
Thanks for the feedback everyone,

Hello Geoff We were faced with the same type of space limitation in our hood. What we've done is vented our oven to the fumehood's duct via the thermometer hole (we removed the thermometer adaptor which left a 3" hole) on the top using 4" diameter metal ductwork. There is a damper control in the line allowing us to adjust the rate of exhaust. Voila! No new hood needed, more room in the hood, no potentially noxious fumes in the lab. FYI the vapours from curing epoxies are noxious, and can cause susceptible people to develop mucous membrane irritations and swelling.

The question is primarily aimed at the Biological TEM crowd.
Has anyone experimented with using a Heat block unit for curing plastic instead of an oven?
The reasoning is that a heat block fits in the hood more easily and can be moved out when not in use. The hood space here is extremely limited and the oven typically has been curing Spurr's and Epon type Resins in the prep room, a practice I am not comfortable with (and neither are the Safety folks here).
Looking at the specifications for the Dry Heat Blocks some are +/- 2ºC stability wise in the $200 range with the fanciest models having +/- 0.5ºC range stability.
Yes I am aware of the limitations, specifically sample number, no it wouldn't work for constant routine samples where there's a constant flux, but for individual processes where no more than one or two groups of samples are cured at a time it would seem reasonable.
Thoughts? Experiences? Conjecture? Opinions?

Question: My boss is asking me to investigate the pros and cons of a confocal microscope. Her thought is to not get the new SEM but get a Confocal. Our SEM is 20 years old and I'm really hoping to get a variable pressure unit soon. Anyone have any thoughts on this. What are the restrictions of the confocal. We are a materials/industrial forensics lab and the confocal is to be used to surface evaluations of coatings, etc.

Question: What are the difference in Brightfield, Darkfield and phase contrast microscopes? and how do organisms appear in each of these?
Discussing the importance of safe handling of toxic vapors, liquids, solids (powders and dust), is not worth anything unless it is followed by actual safe laboratory practices and equipment; this is critical to the longevity of students and faculty. Sorry to sound like a stuck CD but toxic vapors may do more that cause rapid sensitization or neurological damage. Think long term and that what we handle as graduate students may hit us with devastating diseases 30 or 40 years later. I know from experience that vapors can do more that cause neurological damage (been there, have that) but also damage the lungs necessitating a lung transplant, IF you are incredibly lucky as I have been. A fellow grad student was not so lucky with another disease. Were these caused by EM grad work and careers? No one knows (but it is suspected by medical experts) but do you want to take the chance?

What have people done about setting up constant temperature enclosures for their Zeiss LSM 510 NLO on Axiovert 200 scopes?? We know we can purchase one from Zeiss for something like $18000.00. But we also know we can design our own, though this option is a bit difficult with the scan head box on the side, rather than the back, of the scope. We prefer to heat the whole scope, not just the stage and objectives.
Has anyone designed their own enclosure for this type of microscope?? If not, has anyone found a less expensive option than purchasing the one from Zeiss??
A colleague of mine is a keen photographer and owns the Nikon D70 - basically the same as the D50 (which is reviewed at http://www.pcpro.co.uk/reviews/75059/nikon-d50.html?searchString=olypus+d50+d50 ) . . Although its a great SLR camera it has no macro function at all (unlike all the cheaper compact pro-sumer digital camera's). Thus you will probably need the optional AF 60mm f /2.6D macro lens you mention to get closer than 2 feet or so (although even that is quoted as only going to 22cm). The AF60 f isn't a proper DX lens specifically designed for the small D50 sensor, but I'm sure it works fine. I don't believe there is a DX 'macro' lens on the cards. The macro lens can be used for standard photos as well but its not quite as good as the standard lens for this. There aren't any cheap extension tube rings available either (probably as the CCD detector is a lot smaller that 35mm). I'd try the macro lens out at the local camera store (or buy on approval). I have seen the macro telephoto AF 105 f/2.8 recommended as well for this body, for 'portrait and detailed work' i.e. things a bit further away. Also consider the highly rated Canon 350D SLR with new EF-S 60mm f/2.8 Macro lens ('built for digital').
Although I have four SLR film cameras in the cupboard I have to say I now prefer top of the range compact cameras with active LCD viewfinders (granted its also to do with the price and where I take pictures). Over in the UK there is the far cheaper £340 Canonpowershot S2 IS 'compact' 5MP 12x zoom camera (review at http://www.pcpro.co.uk/shopper-reviews/75287/canon-powershot-s2-is.html?searchString=powershot+s2+is+powershot+s2+is which has a 'stunning macro mode that lets you focus on objects right up to lens face...'. If money is a tight this far cheaper option will no doubt still produce excellent images. It is a bit like an SLR in that it has an active LCD viewfinder showing what the CCD sees. Personally I often prefer an active LCD viewfinder (Canon S2 IS type) to the SLR (D50) purely optical one - you actually see the same thing as the CCD detector (clouds, glare etc...) and you can quickly move the camera about to change the auto-exposure lock settings - granted its viewed at relatively low resolution although with digital gain you can check focus after the pictures taken - and usefully you can easily view the camera setup menu within the viewfinder. I just can't read the standard backpanel LCD display text (without magnifying glasses) and even for images its often useless in bright light. Nip down the camera shop and try them out ? Just add £15 for the mini-tripod to use with the remote or self- timer in case the flash causes wet tissue glare. However these LCD active viewfinders can lead to occasional soft or out of focus images, which you may miss due to the lower resolution viewfinder. So you may have to download to PC and check (not normally awkward in a lab). This should be less of a problem with an optical SLR camera, plus the compacts have fewer, if any, filter or lens options.
So that sounds another option to the Nikon D50 (I don't suppose you will be disappointed with the far more expensive D50 + macro though). For our lab work we make do with a heavily used sub £200 4MP Canon A80 compact.

Dear Valerie,
Standard brightfield or Kohler illumination is fine for resolution and even sample illumination, but on many unstained and live samples it lacks the contrast to pick out any detail. Hence it is ideal for stained sections or specimens that have high contrast (e.g. soot particles). Both phase contrast and dark ground illumination are optical 'contrast enhancer's and require special optics in the objective barrel and./or condenser (although darkground at low magnification only requires a central opaque 'patch stop').
In phase contrast, the contrast within specimens that absorb little of the transmitted light (e.g. live or fixed unstained cells) is significantly increased. It works as different cell regions have different refractive indices. Phase contrast can also be used to further enhance stained specimens, although it is widely used for investigating live cell motility or as a secondary source of information with fluorescence microscopy. There is often a bright halo around the object.
In dark ground, the specimen is brightly illuminated against a black background, and no direct light enters the objective only that scattered or reflected by the specimen. Scattering features are bright with contrast being higher and reversed. Although it offers no higher resolution that a standard microscope, submicron particles such as the larger viruses can be seen as dots of light.
There's also differential interference contrast (DIC) that gives a relief effect and less of halo around the specimen than phase contrast optics. With all with image contrast enhancement, the specimen and coverslips must be clean with no air bubbles. Coloured in-line filters can also increase contrast in stained samples, particularly with B&W hi-resolution CCD cameras.
Contrast in a standard brightfield microscope can be increased by simply by closing the aperture diaphragm in the condenser or moving it off-axis (oblique illumination) giving a shadowed relief effect (which is also seen if a desk lamp is left on next to the microscope).
See 'Introduction to light microscopy' by S Bradbury & B. Bracegirdle (Royal Microscopy Society microscope handbook 42) or a similar text. There's also a really excellent on-line tutorial at http://www.microscopyu.com/ that has all the pictures and info (you need Java installed on your browser for the tutorials).

Question: I'm looking to obtain microscopes for 7th graders in Life Science so that we can look at cells and other cool stuff. I wanted to ask: What is the best microscope for the price? What type of magnification will I need to see cells? Will we be able to see individual cell parts with an optical microscope? What companies donate microscopes to schools?
I was under the impression that all that an SEM was really good for was for the evaluation of the surface of non-living materials (unless you are into vaporising bunnies). Confocal might be OK for polymer coatings, but SEM images are rather in a different league to confocal in terms of resolution and clarity. There is an article on polymers at http://fire.nist.gov/bfrlpubs/build04/art034.html .
I have occasionally viewed things under confocal that I am used to seeing under SEM or even under LM phase contrast with a CCD camera, like recovered inhaled mineral fibres, pollen grains, or Nuclepore filter surfaces, and thought wow they look really bad. We only use laser confocals here because our delicate water based life forms aren't very happy in a vacuum (and to be honest the confocal does come alive with intra-cellular fluorescent markers). In my last days at Harwell 10 years ago a new Camscan SEM was a revelation with digital image VDU, PC control and Quantimet style image analysis, compared to our older SEM machines (picture quality was pretty similar though).
I'm sure the manufacturers would be very keen to demo a confocal at their head office (our confocals are designed for living cells). I would have thought you could rent time on a local confocal if it is needed occasionally (we charge £10 an hour over here).

Keith

Judith, One question to ask your boss is, "How much do we use chemical information (i.e. x-ray data) in our analyses?" Confocals don't generate x-ray data. I'm not familiar with them and others may have better information, but is there any chemical data generated? In my experience materials and forensic work is often more concerned with the chemistry than the images.

Title-Subject: [Filtered] Leveling platform for microscope
Question: I'm looking for a relatively inexpensive mechanical leveling platform that can be put onto a standard microscope stage. I want to be able to level a flat sample for imaging across both x and y directions. Any ideas on sources for the above would be approciated.
We used to prepare blood cells using standard fixation and dehydration but then transfer into a Freon. Once in the freon you could just put a droplet of the sample solution on a nucleopore filter. The freon would evaporate instantly leaving lovely dried cells.
We tried this recently with the remains of freon we have had around for years. It did not work well so I am assuming that the freon absorbed water over the years and is not longer usable.
I do not know that type of freon this was as I inherited it. Most types are no longer available. Does anyone know of a type that is still available and can be used for this purpose? Any other hints for processing blood cells? We can do standard CPD but this other method was soooo nice and easy with such good results when it worked.

Have a look at the QX-5 computer microscope by Digital Blue - its great fun and puts the image on a PC screen. I knew it as the Intel QX-3. Its cheap at $60 and can even be modified to include an Abbe condenser to considerably improve images (see http://micro.magnet.fsu.edu/optics/intelplay/index.html (the QX-5 is basically the same microscope as the discontinued Intel QX-3 but updated). I assume 7th graders are around 11-12 in age (year 7 in the UK). Once on the PC the 640x480 images can be manipulated and pasted etc, and it does time-lapse for living plants growing and small animals.
Website for the QX-5 http://www.playdigitalblue.com/products/qx5/info/. Every school in the UK was given one of these in 2002. I've seen it for sale at http://www.toygroove.com/qx5-computer-microscope.html . It's not got the resolution of even a standard 'school' compound microscope though. The QX-5 is also a bit more delicate for unsupervised boys so may be better suited to teacher lead demos.
If you want a 'real' microscopes have a look at companies like Meade who make a variety of microscopes from $70 to $700 http://www.meade.com/readiView/. They will all show simple things like cells with stained nuclei, but naturally the more you pay the better the view (and the more expensive ones come with an internal light source). 4x, 10x & 40x is fine for seeing cells (with a 8x eyepiece that's around 30x to 400x magnification), any 100x objectives are fairly useless at these lower prices ). No doubt other schools and colleagues can advise on brands. Our research microscopes cost nearer £200,000.
Excellent pre-prepared stained slides of plant stems and leaves or bits of rats, insects etc.. can be bought, but they tend to be expensive and are easily broken. Mounted slides keep well so 'vintage' ones even from 50 years ago can still look OK.
Have a look at ebay.com for student microscopes or slides as they will often be cheaper second-hand (e.g. Bausch & Lomb) or on offer (Meade sell their via their factory outlet). Probably best to avoid children's toy compound or unbranded microscopes, although you can see something down them and they are very cheap second-hand. Watch out for the delivery charge and check their feedback on ebay. Old microscopes may need careful cleaning (very soft tissues).
Generally carry the microscope by its back (something that caught me out when teaching - I hadn't carried a research microscope for years as they are bigger than a desk).
Also Google search the net for best prices and reviews (sometimes lab supplies like slides are expensive on ebay). Unlike the QX-5 you will need 1 compound microscope per pair or small group or bored queue. You can still get one QX-5 as well for teacher demos.
By the way do try growing crystals on a slide, a few drops of a saturated solution of salt (NaCl) or copper sulphate will grow superb crystals on the surface of a slide when viewed under a microscope (but it takes a few hours for the crystals to form and they often look best before the liquids all gone). Make sure they don't drive the objective tips into the solution. It's not biology but its fun.
Being in teaching myself a few years ago I didn't find any ready source of free donated compound microscopes in the UK. Being in a poorer area our parent association generated nothing either. However our village Playgroup (kindergarten 2-5 years old) did quite well by sending begging letters and charity grant applications far and wide, so give that a try.
Hope this is of some use.

Keith

try Vertrel. this is an 'environmentally friendly Freon replacement' brought to us by Dow, the same people who gave us - you guessed it - Freon. all considered, we can only assume it is environmentally friendly in that there is currently no evidence of damage which it can cause.
having said that last sentence, i use it inplace of freon for cleaning scope parts and for purifying virus for different uses. it is almost as expensive as freon, but i think you can get it in 1L bottles (we use enought that we usually buy 4L bottles).
what is a reply that does not flog our own papers - for a reference see: Mendez, Hermann, Hazelton and Coombs. 2000. A comparative analysis of Freon substitutes in the purification of reovirus and calicivirus. Journal of Virological Methods, 90:59-67. it is available as a free paper in .pdf form from the journals division of Virus International, a section Elsevier has.
but i have no stock in Dow or Elsevier, nor interest in use of Vertrel other than our paper, and references look good in the citation indexes, not?

We used to prepare blood cells using standard fixation and dehydration but then transfer into a Freon. Once in the freon you could just put a droplet of the sample solution on a nucleopore filter. The freon would evaporate instantly leaving lovely dried cells.
We tried this recently with the remains of freon we have had around for years. It did not work well so I am assuming that the freon absorbed water over the years and is not longer usable.
I do not know that type of freon this was as I inherited it. Most types are no longer available. Does anyone know of a type that is still available and can be used for this purpose? Any other hints for processing blood cells? We can do standard CPD but this other method was soooo nice and easy with such good results when it worked.

Dear List, A colleague of mine asked me to post this:
Will you please forward this ad:
The equipment is: Model: Philips Transmission Electron Microscope EM430 Serial #: D614
The machine has not been in service for the past five years. It comes with full set of manuals. It is offered as is, without sample holders for free, but the receiving party is responsible for relocating it. Caltech requires the receiving party to sign a liability release on the materials themselves. We only engage with parties who are prepared with a rigger (professional person) and a big enough truck. This professional should know in advance the exact model.
Thanks.

sorry listers, sometimes the fingers move faster than the brain. both Freon and Vertrel are products of du Pont, not Dow, as i previously stated. i did know better.
should also point out that there are other environmentally friendly replacements for Freon. i think most of our EM suppliers can give a line on other products. i would check with SPI on that because i know they can recommend alternatives.
no, no interest in du Pont, or SPI either.

Title-Subject: [Filtered] MListserver:ISI service manual
Question: Hello everyone Last month we get as a ìgiftî a SEM, an ISI model DS-130. As far as the last user say it was in working condition when they use it for the last time 5 years ago. We are going to install it but we would like to have a copy of the service manual of this instrument. As far as I know since several years ago ISI is out of business, so I would like to know if some one of this list has the service manual for this particular instrument. If some one has it please contact me off line to arrange the way to have a copy of it. Thank you in advance for your help CS Mexico
I am new in the listserver and I have tried to search the archives before posting my question, but I have found no clues so far. I am trying to analyze EDS spectra taken from a Phillips CM-200 TEM with an EDAX-DX4 system. I would like to use the DTSA spectrum analyzer; but the data format of the DX4 system seems not to be suitable to be imported to DTSA. Does anybody happen to know if there is any free utility to convert .spc files to the EMSA or MSA data format? Any advise will be greatly appreciated.

I don't know if any microscopists answered your question (none were posted) so I'll reply.
Generally to use these very expensive microscopes you need a good biology degree (cell & molecular biology). Most microscope 'users' will have then gone on to get a PhD (doctorate) in cell or tissue biology (working with animals, plants and/or bacteria & fungi). Its then that they may start to use these types of microscopes a lot, as fluorescent markers are used to trace intra-cellular biological processes. So it takes a lot of work to get to be a regular user. The only downside is that even with a PhD in biology you may not succeed in research as it is quite competitive. It helps if your PhD tutor is well known, and the research is in a popular area like how to stop cells becoming cancers (or curing blindness in our institutes case). I'm sure your Biology department at your university can advise further.
There aren't many openings for non graduates, but sometimes research organisations will take on technical support staff with good school exam results (normally aged 18-20) and train them in things like this. In the UK such staff will often be expected to take a part-time biology degree or similar qualification while working (paid for by the organisation).

I would think that difference in resolution may be due to the nature of the measurement.
If we can only make measurements as fine as D in the image, I would think our error in the Z direction would be D/Sine(theta) or about 11D for 5 degrees of tilt (sine(5)=0.087)

I think we are talking really about measurement error, not about resolution.
If dP - error of parallax measurements (x direction), then dZ = dP/2*sin(theta/2), if we know exact tilt angle (theta error is zero). If theta=10, then dZ=5.7*dP. For relatively flat surfaces we can use tilt angle equal to 20 degrees and even higher. For theta=20 dZ=2.9*dP. Not too bad, since dP usually is smaller than 1% of the field of view.
Error in theta measurements gives another component of dZ. Unfortunately some microscopes does not equipped for good theta measurements and for them theta error could be as high as 1 degree. In this case dZ is about 10% of the measured value of z (at theta=10). For microscopes with a good goniometer this part of error is pretty small and in any case can be minimized by increasing theta.

I've been wondering the same thing as Ariel Danon. I have the EDAX Power MX system, a Macintosh computer based system - a very rare bird, indeed - mounted on my FEI CM-12 TEM, and the quantitation has developed some bugs over the years (software version 1.00). Like Ariel, I cannot get DTSA to take in the EDAX format .spc either. I've been told that if I could save the spectrum as an EXCEL spreadsheet, I could import that into DTSA, but my software version 1.00 apparently will not allow me to do that.
Could someone familiar with DTSA and its import function perhaps give Ariel and I some ideas on how to get .spc into DTSA?

A fellow by the name of David Vowles (djv23-at-cam.ac.uk) wrote a program called Spectrum Plot that reads and converts many formats of EDS files. It lists EDAX as one of the supported formats. I took an interest because of its support for Link ISIS format and for batch file conversion. If your EDAX saves files with an extension of .SPC there may be hope.
I got a copy of the software on CD from David. I don't know if he has an on-line copy of it. I don't think he would have an objection to me forwarding my copy, but you should probably check with him first.

I am seeking a clear circuit diagram of vacuum board for our JEOL JEM-100C TEM system. We are running into a vacuum trouble because the diffusion pumps did not work. We could not read any numbers from the existing diagram we have in the lab. The number of the diagram is E-2-14.
This is a old old machine I have to say. Any help would be appreciated.

I'd like to use FITC-conjugated 6 nanometer beads for several cytology projects that will be subjected to confocal micrography. I checked with several companies but they don't seem to have the 6 nanometer size that I'd like to use in my experiment. Does anyone know of a company that sells them?
Thanks, Carlo

I don't know if they have FITC conjugated beads, but definitely beads (including 6 micron) with fluorescent dyes with a comparable excitation/emission spectrum (and much more photostable than FITC).
Good luck and best regards,

I tend to buy fluorescent beads from Polyscience or Molecular probes. In my old days at Harwell we used to make our own particles (often radioactive fused aluminosilicate clay particles [FAP] as in-vivo radio-tracers rather than fluorescent though). 0.006 um is rather small though, as most manufactured 'standard' sizes of particles seem to only go down to around 20nm, e.g. see http://www.dukescientific.com. Personally I've never used a size of fluorescent particles below 0.04 um (and even these naturally behave more like a stain, being too small to resolve optically).
However Polyscience and Molecular probes both have a bespoke service for custom microparticle production and should be able to help for a price:
"Our Polybead® polystyrene particles are excellent for a variety of applications because they are monodisperse. In addition to the standard products contained in our catalog, we can synthesize materials designed to your specifications. If you require a custom microparticle preparation, please contact us for a quote. "
"We can tailor-make colored and unstained microspheres of many sizes, surface chemistries, densities and volumes to meet the diverse needs of customers, including academic, industrial and government laboratories, as well as major global diagnostic companies; please contact our Custom and Bulk Sales Department for more information."
It might be useful to have an idea of price for these bespoke particles if you have or get one.
Regards
Keith

Good morning, List,
I'm looking for recommendations for a tabletop B/W print processor (Like the Ilford 2150 RC) for a new darkroom. (Yes, we have digital, but I still want to be able to use film). Thanks.

I don't know if such a beast exists anymore. Did you know that Ilford is in receivership and that Kodak will stop making B&W paper at the end of the year? I love film, real film. Most of my many cameras are 'antiques' by today's standards. I have books on photochemistry and I mix all of my developers (film and paper) from scratch. I would just buy a good printer for B&W work and a film scanner.

This is the new replacement for the Coolscan 8000ED. I'm not sure what Nikon did to improve an already great scanner. If you want to scan TEM negs, they do not directly fit. The sides need to be trimmed away a bit and then use the 6x7cm holder. What media do you intend to mostly scan? Unless you are doing 35mm, the 8000/9000 at high rez will generate HUGE TIFF files. If you back off on rez, then size goes down. But then, you could buy some lesser rez scanner.
One of the big things the 8000/9000 have going for them is very high Dmax (4.8). Lesser scanners typically do not have this.

Question: I have a fair ($600) stereo trinocular disecting microscope with a ccd color camera attachment. My question is: what is the best (under ~$200) video capture card with software that I can use to display images on a computer for class demonstrations. The camera output is "BNC" F and S video.
I guess I don't understand why you can't just run the S video output to a television monitor for the class to see. I would think your audio-visual department would have a compatible television.

The Video ZFL Scope offered by klughammer bio gmbh, Germany is a Macro/Micro fluorescent vision system that utilizes interchangeable professional fluorescent cubes and internal focus to create an image compatible with most existing camera systems. It is a simple means of doing very sophisticated, task oriented fluorescence without the expense and complexity associated with a fully loaded research microscope.
Basic Components of the ZFL Video Fluorescent System are:
1. A light source emitting the wavelengths required to cause the labeling dye to fluoresce. Two different remote light sources are available, a halogen light for the longer wavelengths, and a metal arc lamp for the UV.
2. An integrated cube that optimizes performance by stopping all but the desired (excitation) wavelength from reaching the object and then stopping all but the fluorescing wavelength (emitting) from reaching the camera. There is a multitude of off-the-shelf cubes available depending on which labeling dye is being used.
The system permits the usage of all standard Olympus BX2 Fluorescent Cubes, which are available from multiple sources. These are captured singularly in a quick change holder requiring only a minute to interchange.
3. A camera whose sensitivity and bandwidth are adequate to handle the fluorescing light levels (which can sometimes be minimal).
4. Optical and mechanical parts
The ZFL system is suitable for operation in either Macro or Micro mode.
If you would like to receive more information, please contact us.

Thanks to all of you who responded to my post about B/W printers - I'm digesting the info.
Here's another query. I know that this has been discussed before, but I couldn't find the thread in the archives. We're re-evaluating what we charge our users for EM services (embedding, sectioning, scope time, etc) and would like to have an idea about what other academic institutions charge. If anyone is willing to discuss this, would you please e-mail me off-list or call me? Thanks.

Hi all- I'm in need of some ITO (indium-tin-oxide) coatings on glass substrates and have obtained a few quotes of $800 or so. I can get an ITO sputtering source (for about $500) that will fit in my lab DC sputtering unit. The questions I have are: will a small sputtering unit be adaptable to make good conductive as well as transparent ITO films?? Do I need to introduce O2 as well as Ar to get the stoichiometry correct for the oxide? What about the DC potential...is it OK at about 1KV? What about vacuum?
If anyone has already setup a small ITO coater maybe they can share their experience... Thanks! Brian ____________________________________________________ Brian McIntyre University of Rochester Institute of Optics RCEMLab 585-275-3058 585-244-4936 fax

Title-Subject: [Filtered] Preservation of Eyes
Question: Good Afternoon, all:
Sorry to have to use the web form; for some reason our servers are rejecting my message when I tried to send it normally!
We have an upcomming project involving eyes from multiple species. Traditionally, we've collected samples in Mod. Karnovsky's fixative with no problems, but our opthamologist seems to remember a protocol involving sucrose that worked better. He can't find it in his literature, and we dug though our books and couldn't find a thing!
Does anyone have a special recipe that they find works well on eyes?
Thank you all! -Chris

If you are looking for ITO coated microscope slide or cover slip type glass, these are standard products and are described on URL http://www.2spi.com/catalog/standards/ITO-coated-slides-resistivities.html
If you need something custom, contact me off line and I could quote you pricing for what you would be needing. You have not mentioned it, but the resistivity, which depends on ITO coating thickness, and which will ultimately determine the % transmittance, will have some influence on the pricing.
Disclaimer: SPI Supplies offers ITO-coated glass slides and cover slips as standard products.

Title-Subject: [Filtered] FL digital camera
Question: Hi all,
We are looking for low-budget color digital camera for fluorescence light microscopy. Our Micrscope is olympus BX-51. We intend to observe bacteria and biofilms.
Could you elaborate a bit more? Why did the other resin's fail? What solvents did you use to dehydrate the samples? Are you just putting dried clay in the resin? Is the problem at the section end, or the embedding end? ...
It would help to identify what direction to go in.

Hey everyone, Our group is interested in purchasing a new dimpler. Does anybody have any opinions of which dimpler to purchase? We've been looking at ones by South Bay, Gatan, and Fischione. They are all around the same price range, so we're not concerned too much with cost, we just want to get the best dimpler. Any feedback is appreciated! Thank you! -Andrew Roelant

Tina Williams wrote: =============================================== Can anyone suggest a good resin for embedding clay? We have tried Epon, Spurrs, and LR White. ================================================ "Epon" should work, at least our own SPI-Pon 812 resin works in our own laboratory and when there have been problems with platelet "pull out" during sectioning, adhesion with the embedding resin can be enhanced through the use of 3GTMO, see URL http://www.2spi.com/catalog/chem/trimethoxysilane.shtml
If you are embedding entire clumps (I think there is a more technical word than "clumps"), a vacuum embedding would be more appropriate in order to get complete infiltration of the resin.
You should not have to rush out and purchase SPI-Pon 812, at least some of the other "Epon substitutes" should work just as well, but not necessarily all of them since they are not all the same. One trick for making it "work" is to cure to a harder rather than a softer block.
If none of these suggestions work, let me know, as there are some other tricks on can consider using, depending on the circumstances of your clay samples.
Disclaimer: SPI Supplies is a supplier of both SPI-Pon 812 and also the adhesion promoting compound, 3GTMO.

first of all, I would like to thank all who responded my question on DTSA spectrum analysis last week. The problem I had was that our version of the EDAX-DX4 software (2.11) was not the right one to get the .spc files converted to .msa files; in fact it was a very old version and did not contain the utility SpecUtility.exe. Once the version was changed, it worked and I got my files converted. But...the problem is not completely solved, as DTSA seems aparently not to import the converted .msa files, with none of the two plugins specified for that task, so any clue will be appreciated.

I thought it might be helpful to clarify that South Bay Technology actually manufactures 2 Dimplers®. The Model 515 Precision Dimpling Instrument and the D500i Dimpler®. The D500i was previously produced by VCR Group. South Bay Technology acquired VCR Group back in 1998. I won't offer you my opinion of which Dimpler® to purchase as I doubt it would be that useful coming from one of the manufacturers! Of course, I would be available off-line to discuss any of your requirements.
DISCLAIMER: South Bay Technology produces equipment and supplies as described above and, therefore, has a vested interest in promoting their use.

I'm speaking from memory here - I haven't checked my old notes, but I think I may have seen a problem like this before.
The MSA file specification is very precise (it is available from the MSA web site), and specifically requires that the data values be given as real, not integer, numbers, and is also very specific about how the delimiters (commas, if my memory serves) are placed (for example, the last datapoint on a line has to have the format "xxx. {ret} " where the {ret} means the end of line, and no extra spaces are allowed. I don't think that the EDAX specimen conversion utility follows this convention properly, and instead writes numbers without the decimal point.
(I have EDAX, Rontec and Oxford systems - I'm certain that the Oxford files read into DTSA fine, and I don't recall ever trying with Rontec, so I'm pretty certain it is the EDAX ones I had the problem with.)
DTSA follows the convention precisely, and then gets confused reading in the converted files. You can read the file into a spreadsheet and adjust the format there (which is what I have done when I have needed to take files into DTSA), or it would be simple to write a Basic utility to reformat the file (but I haven't done that).
Better, EDAX could correct their utility!
Tony.

This is regarding the earlier questions about embedding clay.
We used water/ ethanol, propylene oxide, and water/ acetonitrile for dehydration. We found problems with poor infiltration (in Epon, Spurr's, or LR White). Thus, sectioning problems. We are willing to try other dehydration protocols. Today it was suggested to try cryoultramicrotomy, however we do not have a set up for this.
Thanks to all those who have responded. Please keep the suggestions coming.

} The MSA file specification is very precise (it is available from the MSA } web site), and specifically requires that the data values be given as real, } not integer, numbers, and is also very specific about how the delimiters } (commas, if my memory serves) are placed (for example, the last datapoint } on a line has to have the format "xxx. {ret} " where the {ret} means the end } of line, and no extra spaces are allowed. I don't think that the EDAX } specimen conversion utility follows this convention properly, and instead } writes numbers without the decimal point. }
DTSA also expects Y msa format (multiple columns of counts) so if your msa exporter does XY format (two columns of energy and count at that energy), DTSA will not import the file properly. Both formats are correct in the eyes of the msa format, the msa importer must be smart enough to handle both.
Also watch out for the end of line terminator. There are three types, dos, mac and unix. The msa standard does not define which flavor is expected so a smart reader needs to handle all flavors. So if you are exporting on a dos/win computer and importing on a MacOS computer you will need to convert the end of line terminator.
If you want an easy way to do this, download our Revolution program. It will run in demo mode but this mode will allow msa import and msa export. Both X and XY are handled for both import and export. Revolution runs on both WinOS and MacOS platforms. We can handle just about every msa file I've come across and if you have one that has a problem, sent it to us and we will fix the issue.

Question: I just purchased an Zeiss Ultraphot II for use in my photography hobby.
It has a plug with two round prongs on the microscope body for the electronics in the photo head.
I have a powersupply drawer but it doesn't look complete, requires 220 and is huge. (my wife already doesn't like the size of the microscope)
Can anyone tell me what the input voltage and amperage needs to be and possiably suggest a power supply?
Your submission of other meetings will be very appreciated (submission form is accessible from the page mentioned, the direct link for the submission is http://www.petr.isibrno.cz/microscopy/PMRform.php).

Question: We are planning to purchase a stereomicroscope for high school biology, earth science, etc., plus looking at fossils, and had a question about recommended magnification. The scope we are looking at comes in 10/20, 10/30, or 20/40 magnification. There is also a .5 reducer and 2x supplementary lens avail. as well as higher power eyepieces. What magnification might be best for our purposes?

Has anyone experienced (and fixed) the following Nikon Coolpix 995 problem?
Camera reports: "This card cannot be used" - on power-up.
-Battery is OK. -Have tried camera system reset. -CF card works in other similar Nikons. -Working card from another Nikon presents same problem in troubled camera. -No bent pins. -Pin corrosion unlikely - Camera used little and well kept. Also, card has been in/out a number of times. -Camera will skip the format selection in the menu - Not selectable. -Camera appears to function normally otherwise - what functions there are with no card, anyway.

I have had the same problem with another Nikon camera and found that it was the card being formatted incorrectly. What I did was put it into a card reader on a PC and then formatted it to FAT and it worked OK. The card company told me as did the local Nikon repair facility that I should then format the card in the camera a couple of times. DO NOT use FAT32 as it will give you that error. Whether this is the problem, I'd like to know.

A client needs to have cell cultures of endothelial cells embedded for TEM. I would be grateful to hear (off line) specific recommendations for a substrate for growing the cells. The substrate will have to withstand ethanol and propylene oxide, and have good sectioning properties when used with an Epon type resin. I would also appreciate recommendations for fixation.

I have many times grown endothelial cells on Aclar Film. EtOH sterilize the film. Put it in the bottom of the TC dish. Add your cells. Some of them will grow on the bottom of the film. No problem. Fix and embed the film with the cells. The film, in my hands, is impervious to all treatments. When the block is hard, just peel off the film and your cells are in the plastic. You can section in either orientation, as your want. David

One commonly used substrate is the Thermonox line of cover slips, available from many suppliers. They come in various sizes and the cells can be grown on them, then the coverslips with cells fixed, dehydrated and embedded as usual. The section quite well, except for an unfortunate tendency for sections not to detach completely in the boat and to pull the next section back over the edge of the knife. This can be remedied by making a pointy block face or by using a razor blade to make a line just beneath the top of the block face so the section detaches just before the end of the cutting stroke.
The cover slips can be cut into pieces small enough to embed in ordinary capsules and are normally used to do cross-sections through cell layers, as opposed to "top down" sections. With care and creativity you should also be able to get other orientations, but it would be much trickier.
I'm not 100% sure of their compatibility with PO, but I don't believe it's a problem. They stand up fine to EPON and other resins we use.
An alternative is to grow the cells on any old cover slips, run them through the fixation, dehydration, and infiltration steps, then place them cell side down on top of resin filled (with a resin meniscus slightly up over the top) embedding capsules. Polymerize them as usual, taking care that they are level so the cover slips don't slide off. After everything is mostly hard, immerse the coverslip/capsule assembly in liquid nitrogen, then snap off the coverslip from the capsule. If all goes well, and it usually does, the cells with transfer to the resin in the capsule and form the top layer of the block. Identify your area under a light microscope, trim away the rest (careful!), then start taking sections. Remember that there is only one cell layer----if you cut through it and discard it by mistake, it's gone.
Good luck.

Question: We have been preparing coated grids for TEM for a long time, with relatively little trouble. We follow the protocol for preparation of formvar coated grids from the Bozzola and Russel text, Electron Microscopy. I recently tried to prepare grids with very little success. I was using fresh formvar solution from EMS, thinking that our old solution might be the problem. I tried several different brands of slides as well, all leading to no success. Have any of you out there experienced similar problems? Any ideas would be greatly appreciated. You may reply offline if you wish. Thank you.
My department would like to improve the vacuum system in our old scanning electron microscope JEOL JSM 5410, which is equipped with Si(Li) EDS detector. The main reason for this step is to prolong the working time of the tungsten filament and/or replace this type of the source with LaB6. We would like to diminish oil contamination coming from roughing and diffusion pumps as well. We have got two ideas concerning this matter. One option is to attach ion pump to the existing pumping system to improve vacuum to 10-7 mBarr and the second option is to remove diffusion pump and replace it with turbomolecular pump. My question is the following: What are advantages and disadvantages of such upgrade of the vacuum system? What kind of pump should be installed to our microscope? Have you got any experience with these two types of pumps? Is this modification worth doing?
Another question concerns the electron gun of JEOL JSM 5410. Should we change the tungsten emitter into LaB6 if we would like to perform X-ray microanalysis? I heard that this type of gun is not recommended for quantitative X-ray microanalysis due to its poor stability. It is also not so easy to do such modification I suppose... Could you recommend us something in this matter as well?

As an institute of ophthalmology I suppose we should be able to help - but I'm now in the cell biology department where tissues are slightly frowned apon.
Generally sucrose solutions are regularly used as a cryoprotectant. For non-cryogenic light microscopy, sucrose immersion is generally a poor choice for paraffin wax embedding (I always used Spurr's, LR White resins etc. as my work always involved considerable image analysis). If you use paraformaldehyde only (rather than with Gluta-aldehyde) some do add sucrose to stop strange effects (like blebbing in fixed cells) but this again this may affect the tissue for paraffin wax embedding.
Glutaladehyde is regularly combined with paraformaldehyde, as in Karnovsky's fixative, to improve things. These fixatives can be used to fix tissues for paraffin embedding, but the tissues will be quite brittle (which is why sucrose is occasionally used, and why I used resin embedding). Standard gluta-aldehyde recipes are used here to fix eyes that are going to be embedded for TEM and ultra-sectioning.
Glutaraldehyde is a fixative regularly used for electron microscopic studies, and I always used this as a secondary fixative after initially inflating and fixing lungs in osmium tetroxide dissolved in Freon FC-80 - a method that even fixed macrophages in-situ on airways. I used to prepare samples more in a TEM manner as I required high quality sections for lung distribution and micro-dosimetry studies (often with CR-39 autoradiographs coupled with serial stained histology). Once fixed over a few hours, fixed tissues were then stored refrigerated in cacodylate buffer (that often has a little sucrose to help with the osmotic pressure). Osmium fixes lipids rather than just proteins so really helps on section quality although its highly toxic properties and 'creep' are a real pain (although once its black it's osmium dioxide and stable - when its toxic it's invisible).
Unfortunately all my relevant research papers and fixation recipes are up in the attic at home somewhere, so I am writing from memory. My recipes were no doubt similar to that found on the web today.
Hope this is of some help.
regards

Dr Grzegorz Tylko,
I am not intimately familiar with the specific SEM you are referring to, but I will comment a bit on the questions you've asked. If you could answer some questions, then a better opinion could be formed.
Can you perform light element analysis with your EDS detector?
What pumping oil is used in your diffusion pump?
Generically, the vacuum upgrade would be best done by removing the diffusion pump and putting in a turbomolecular pump. There are vibration isolation issues with this upgrade that you have to address carefully. If you were to put an ion pump onto the diffusion pumped system, how would you connect it if this is being done on the chamber? I wonder about the lifespan of your ion pump if it is used to pump the diffusion pump vapors from your diffusion pump. The LaB6 systems I have worked on have an ion pump connected to the filament side of the SEM. The vacuum piping that runs to the filament has an isolation valve that seperates the head of the gun from the chamber. An ion pump is connected at the electron gun head and always pumps the head of the gun.
The instrument I currently use is set-up to run both W and LaB6 filaments. I never use the LaB6 option.
For what's it worth....

I have experience with both pumps. An Ion pump is mounted to the gun chamber. It will not solve your oil vapour problem. You can install a liquid nitrogen baffle (if you still can find it in the market, one of the instruments I used before had it) above the diffusion pump to trap oil vapour. I think this is least expensive to solve oil vapour problem, but you need liquid nitrogen. The next choice is what you have thought of, i.e. change DP to Turbo pump with some modification of the circuit.
An Ion gun is different from a tungsten gun; and there is an Ion pump attached to the gun chamber. So, I don't think that you can simply switch to LaB6 emitter in a tungsten gun. LaB6 will fail quickly without an Ion pump and it is expensive. An Ion pump can only be started up when the vacuum is very good, say 10-6 Torr. The LaB6 crystal must be warmed up slowly. You may find better resolution but do you really need it? We do not think so, and our instruments are without such an expensive option now. If you want a brighter and more stable beam for X-ray analysis, that is another subject which I am unable to comment on.

I would say a replacement of DP to a turbo molecular pump is a good choise as long as you could find a way to isolate the vibration and modify the circuit. For Turbo Pump, I would suggest purchase the pump Balzer simply because you may expect longer lifetime. Wish this will help.

If you don't already have a foreline trap, I recommend added one. They are cheap, simple, and very effective in diminishing backstreaming. In the past I have used some from M.E. Taylor (www.semsupplies.com), but there are many others available.
The ion-pumped gun with LaB6 will cause little or no improvement in backstreaming. LaB6 is inherently more unstable than tungsten. It's normally not a problem, or even noticeable, unless you are (as you mention) doing quantitative EDS, or even quantitative time-dependent image analysis.
Good luck,

I have even found that nose grease from different people can have different properties, so if there are new people in your lab, and they are using nose grease, have them let others donate to see if that changes things. I have found that Apiazon L makes a suitable grease, and I have floated films off using .25 g of Alconox in 1 L H2O when I have used Apiazon.

OK, I've known about and used the nose grease/Formvar thing for years, but for some reason just now it struck me as a real goofy "black magic" sort of thing that must seem pretty weird to non-microscopists. Innocent people who stumble on to the list must think we vacation at Hogwarts...
Anway, to add some more eccentricity to the thread, my old boss (Larry Thurston) swore that after spreading nose grease on the slide, the best thing to clean the excess off with was your dirty lab coat. Not a clean one, heaven forbid, or the slide might not be slippery enough to get the film to separate. Always worked for me...
Any more potions, charms, spells or jinxes? They're really quite fascinating.

1. i've always used dichloroethane for formvar. what advantage would there be to chloroform - how well does work?
2. ok, i gotta plead ignorance. for delicacy perhaps we should use apiezon for the example and leave 'nose grease' to our fertile imaginations. but in 35 years i've never heard of using apiezon to help get the formvar off the slide for coated grids. i'm deeply intrigued. enlighten me. enlighten the rest of us. it could be a good trick to know.

I know of a retired scientist who had used sucrose in her research on eyes. The reference is as following: Yang, W.C., M.J. Hollenberg and J.P.H. Wyse. Morphology of the retinal pigment epithelium in the vit. A deficient rat. Virchows Arch. B Cell Path. 27, 7-21 (1978)
The eyes were removed form the animal and punctured at the ora serrata with a razor blade. They were then fixed by immersion in a mixture of 2% Paraformaldehyde and 2.5% glutaraldehyde (after Karnovsky, 1965) in 0.1M Sodium cacodylate buffer, pH 7.3 for 4-5 h. After removal of the cornea and lens the eyes were then rinsed overnight in 0.1M sodium cacodylate buffer containing 3% sucrose and post-fixed in 2% osmium tetroxide in the same buffer for 2 h. at room temperature. The specimens were dehydrated in a graded alcohol series, cut into smaller pieces with a razor blade and then transferred to propylene oxide. The specimens were embedded in Epon 812 which was allowed to polymerize overnight in a 60 C oven. If you like to have a copy of the paper, she is willing to send you one.

Hi Chris,
As an institute of ophthalmology I suppose we should be able to help - but I'm now in the cell biology department where tissues are slightly frowned apon.
Generally sucrose solutions are regularly used as a cryoprotectant. For non-cryogenic light microscopy, sucrose immersion is generally a poor choice for paraffin wax embedding (I always used Spurr's, LR White resins etc. as my work always involved considerable image analysis). If you use paraformaldehyde only (rather than with Gluta-aldehyde) some do add sucrose to stop strange effects (like blebbing in fixed cells) but this again this may affect the tissue for paraffin wax embedding.
Glutaladehyde is regularly combined with paraformaldehyde, as in Karnovsky's fixative, to improve things. These fixatives can be used to fix tissues for paraffin embedding, but the tissues will be quite brittle (which is why sucrose is occasionally used, and why I used resin embedding). Standard gluta-aldehyde recipes are used here to fix eyes that are going to be embedded for TEM and ultra-sectioning.
Glutaraldehyde is a fixative regularly used for electron microscopic studies, and I always used this as a secondary fixative after initially inflating and fixing lungs in osmium tetroxide dissolved in Freon FC-80 - a method that even fixed macrophages in-situ on airways. I used to prepare samples more in a TEM manner as I required high quality sections for lung distribution and micro-dosimetry studies (often with CR-39 autoradiographs coupled with serial stained histology). Once fixed over a few hours, fixed tissues were then stored refrigerated in cacodylate buffer (that often has a little sucrose to help with the osmotic pressure). Osmium fixes lipids rather than just proteins so really helps on section quality although its highly toxic properties and 'creep' are a real pain (although once its black it's osmium dioxide and stable - when its toxic it's invisible).
Unfortunately all my relevant research papers and fixation recipes are up in the attic at home somewhere, so I am writing from memory. My recipes were no doubt similar to that found on the web today.
Hope this is of some help.
regards
Keith

We use 0.8-1% formvar in chloroform with good success. We dissolve the formvar directly into a new chloroform bottle - this avoids any contamination from lab glassware and humidity in the air. Glass slides are washed in acetone before use. They are coated with formvar using a film casting devise from EMS. Before dipping the slides into a water tank to detach the film, my technician scores the film at the edges of the slide with a razor blade and then breathes gently on the slide. This apparently helps the film to come off in the water. One problem we have sometimes had is the film coming off the grids later on. My technicians have recently found out that this only happens when they use grids that have been stored for various periods of time after washing and drying. So we recommend washing the grids directly before use (at least for nickel). Hope this helps

You did not say what sort of life you are getting out of your W filaments. That is probably critical to know.
We have an older JEOL 840A SEM with a tungsten gun. We changed our operating procedure some time ago because of problems with short filament life ( {30 hours). We decreed that only lab staff would saturate the filament. Users would only turn on and off the high voltage. The scope would ramp up the filament current in about 3 seconds and it apparently caused no great thermal shock to the filament. Our lifetimes improved to around 100 hours. That indicated to us that users were not saturating properly or carefully. It worked as long as casual users were all using the same accelerating voltage. Now, users are changing the voltage on a regular basis and we are again having to train them how to saturate the filament for themselves. I am afraid our filament life will again drop.
You can also try setting the filament further back from the wehnelt cap. It will reduce you emission, but filament lifetime should go up. Steve Chapman will probably comment that such practice is a little misguided. If we want performance out of our scopes, it is necessary to push the filament. I try to balance the two effects. I want good brightness, but I don't like changing a filament more than about every 100 hours. You should find some emission current that provides the lifetime you want.
