Re: Is this Leitz SM LUX any good?

Katie,

The appreciation of the binocular (easy on the eyes) will last when the extra cost is forgotten.
Personally I would vote for the bino.
Brunel is a reliable supplier.

Re: Where to find Diatom Test Slide

Diatomshop.com: I have the generic test slide 2.0, Good quality (diatoms are mounted to the high quality coverglass - not to the slide), but a bit pricy. Diatoms.nl has a series of diatom slides plus 2 test slides with the diatoms mounted to the low thickness tolerance coverglass as well. Fair prici...

Re: Inverted microscopes

Would not mind some input on this question as well.

Observation: most inverted scopes seem to have low na condensors: so my assumption is this limits the level of detail when using 20 or 40* objectives?

When I'm done with a slide, everything goes into a bucket filled with IPA. After a week or two in the bucket I pour off the alcohol and toss the slides/coverslips in the trash. I would avoid having any container of IPA that is not hermetically closed. Alcohol vapors are not toxic but are harmful. S...
