Pleurax seems to always refer to a text I can't get my hands on. I found a german site with some info but it doesn't translate well and seems to rely on an...
John: I can't comment on the old mountants that you listed--a fascinating list, by the way, and in its own right well worth reading. You might want to check...
Hi Brian I know Klaus sells Zrax and may well use it but am still curious. I think I might also prefer to sniff ipa rather than toluene. The interesting ones...
Hi, I recently purchased an AO Series 10 microscope off of ebay. There was no mentioned of a stuck coarse adjustment in the ad, so it's not DOA, I can't...
John, Some of the optical cements are very intriguing. I've used Norland NOA 61 (UV cured), but that's got a RI of 1.56 and you seem to be looking for...
Hi Ron, I looked for your photos with no success. "Another piece of advice I read was to take off the stage and ... Are you able to turn the coarse focus knobs...
Leica has 40x achromat, plan achromat and plan fluorite objectives with long working distances (3.3 to 1.9 mm, depending on coverslip thickness and objective...
Hey guys/gals, like the title says I'm stuck choosing the best microscope between two candidates. Never having used either I would appreciate any input at all....
Hello Ron, It sounds like the "timing" of the course focus worm screw gear is off - you will need to remove the double set-screw which holds the bronze mandrel...
Hello Mark, The Nikon Labophot is a true clinical laboratory grade instrument, which was very popular throughout the 1980's and early 1990's. However, the...
I've had several Nikon Labophots and several Olympus microscopes, but not the CX40. The Nikon E Plan objectives with CFW eyepieces provide really excellent...
I had a similar problem. The problem is most likely dried lubricant gumming up the works in the helical groove that is part of the course focus or dried...
Thank you Fred,your link is helpful for me. So as we all know...spend the money, often you can purchase longer working distance dry-high objectives. ...
Hi There are thinner coverglasses than number 1--they are categorized zero thickness: Thickness #0, Standard Squares, 0.08-0.13mm. You can get them from the...
Hi John: I have always wanted to play with some of the really high mounting medium--but I lacked the time. But you may wish to check the following: ...
Hi Charles, most inverteds are sold with LD objectives that are ment to be used with plastic petridishes 1mm thick and such. The image quality of these lenses...
Mark, I note that it has been suggested that the Labophot is not a good buy for you; I am in no position to comment on that. However that leaves you with the...
... Thank you Greg, your response is much appreciated. Does the equivalent of 650$ sound like a good price for a CX40 to you? It seems like a good price to me....
... which was very popular throughout the 1980's and early 1990's. However, the instrument is oblsolete - and some Labophot 20W halogen lamphouses are no...
My impression is that for an amateur having an inverted 'scope as the only 'scope would be limiting. Inverted 'scopes are used for tissue culture, etc. which...
can infinity corrected phase contrast objectives of other brands be used on a zeiss axiophot? I am considering buying an axiophot stand without objectives but...
Hi, Infinity objectives are not interchangable between brands. Regarding phase contrast, already with 160 mm optics phase-objectives are hardly interchangable...
... I agree with previous posters. I just want to emphasize, NOT to remove the screws holding the main dovetail on the body. Doing that will mess up the main...
Hello Brian, I have had good luck with these. I got very tired of dirty scratched coverslips. They seem to be in stock when I need them and the price is...
... These are nasty, as the formula suggests. I have seen microscopes on which these very high index preparations were used: green and brown corrosive crusts...
