Hi Tommi,
Obviously for LCP glass plates, color versus black and white should make
little difference. For everything else, all darker colors would look
more or less the same and lighter colors similarly so not very useful,
in my experience.

Hi, place a linear polarizer below the tray and one above it, rotating
the top one until you get the desired view.

Hi Joseph,
Could you post the UV fluorescence image? Oftentimes, UV absorbing
objects that do not fluoresce (such as nucleic acid crystals) show up
dark against a brighter background in UV fluorescence.

Is there some sort of consensus on what properties make a crystal diffract
well or poorly? For example, solvent content is assumed to be critical. What
else? Can crystals even grow if there is short-range (less than beam radius)
disorder?

Exposure to light during crystal growth should not have any effect unless
the fluorophore is destroyed by ambient light, which is unlikely.

ClearSeal film from Hampton works with our UVEX UV microscope, despite some
attenuation of UV light.
For hanging drops, Greiner BioOne's films are the best.

Actually, UV fluorescence imaging appears to be a pretty reliable means of
discriminating protein crystals, provided your protein has Trp residue(s).

We are about to release an all-LED based UV microscope for automated
scanning of 96-well plates. Please contact me if you are interested.
