- cuvette is a piece of laboratory glassware used to hold samples for spectroscopic experiments.
- It is usually a small tube of circular or square cross section having one end closed and the other open.
- A useful tool in the lab, cuvette is manufactured using different materials such as plastic, glass, or optical grade quartz.
- Cuvettes with optimum clarity are considered the best as it prevents misreading of spectroscopic data due to the present impurities.
- Similar to a test tube, a cuvette may be open at the top and can be closed using glass or other material. Parafilm can also be employed to serve this purpose.
