A cuvette is a
tiny tube-shaped container with straight edges and a circular or square
cross-section that is used in laboratories. Cuvettes are made to store samples
for spectroscopic analysis, which involves passing a beam of light through the
sample to determine its absorbance, transmittance, fluorescence intensity,
fluorescence polarization, or lifetime. The spectrophotometer is used to make
this measurement. Liquid samples are used in conventional ultraviolet-visible
spectroscopy and fluorescence spectroscopy. Frequently, the sample is a
solution that has the target material dissolved in it. The material is put into
a cuvette, which is then tested in a spectrophotometer.

The
tiniest cuvettes have a capacity of 70 microliters, while the biggest ones have
a capacity of 2.5 milliliters or more. The width impacts how far the light
travels through the sample, which has an impact on how the absorbance value is
calculated. A 10 mm (0.39 in) light path is common in cuvettes, making it
easier to calculate the coefficient of absorption. Although certain tests use
reflection and only require one clear side, most cuvettes have two transparent
sides opposite one another so the spectrophotometer light may flow through. For
fluorescence measurements, the excitation light requires two additional
transparent sides that are at right angles to those used for the
spectrophotometer light. For use with potentially dangerous solutions or to
shield samples from the air, some cuvettes come with a glass or plastic top. Go
