Dear Sir. Concerning your issue about the kind of cuvette that should be used in the range of 200-300 nm wavelength. Quartz cells provide more durability than plastic or glass. Quartz excels at transmitting UV light, and can be used for wavelengths ranging from 190 to 2500 nm, while the crown glass has an optimal wavelength range of 340–2500 nm. I think the following below links may help you in your analysis:

Thanks

Quartz is fine in the vis as well. Try for yourself.

So far Quartz has proven more superior to other cuvette.
