The following passage is awkward:

"Inexpensive cuvettes are round and look similar to test tubes. Disposable plastic cuvettes, while not as pure as glass or quartz versions, are often used in fast spectroscopic assays, where speed is more important than high accuracy."

I would say that plastic cuvettes are just as "pure," wrt chemical composition, as their glass or quartz counterparts, but all absorb in different regions, making them more or less useful for specific applications. Mihovil 02:11, 22 August 2006 (UTC)[reply]

Notice that cuvettes are not only used for spectroscopic experiments, but also i.e. for immunhistochemistry experiments to hold object slides for washing steps. Other cuvettes could be much larger than that showed in the picture.

I would say that Mihovil has it right, and the caption in wrong; to my recollection, we used plastic cuvettes for OD measurements and quartz cuvettes for DNA/RNA, for the reason he states. Also, speaking of clarity as opposed to absorption wavelength, that sample in the photo is not very clear - looks like a used one they fished out of the trash. Photo and caption should be fixed.DLuber1 (talk) 01:59, 27 September 2009 (UTC)[reply]
