Glossary / Cuvette


Cuvettes are small vials that are generally have a rectangular or circular shape, opened on one end, and are designed to hold samples for off-line/in-line measurements for a number of different experiments.

Cuvettes are mostly made of glass, which includes quartz, pyrex, IR quartz, UV quartz, etc.  Some cuvettes are made for one time use, these cuvettes are made from a disposable material such as polystrene and are cheaper in price than their glass counterparts.

The best cuvettes are as clear as possible, with no impurities or defects that might affect a spectroscopic reading.
