Cheap color filters? - Cellophane? Wavelengths? (Jul/14/2010 )
Or if someone has in your department a UV/VIS spectrometer or somewhere else you can rent it. It should be something like this one here , though there are many companies and lots of different machines, mostly unfortunately not cheap...

If you want to do it - pick "UV-Vis" from the main menu, zero on water, place piece of cellophane (eg. 5x5mm or smaller) on the top of drop of water on Nanodrop pedestal, place another drop of water on the top of cellophane, lower the upper pedestal (lid/arm) and measure.
KB, that's exactly what I needed to know. Thank you! I'll give this a shot once I get my hands on the cellophane now that I know how to test it (and as long as the lab that shares it with us is ok with it).
