A cuvette is a type of sample holder for liquid samples. Often, they are made of plastic, borosilicate glass, or quartz. StellarNet offers glass cuvettes for experiments in the visible or NIR ranges and quartz cuvettes for experiments in the UV range.
Cuvettes also come with two or four polished sides. Polishing the sides allows for maximum light transmittance through the cuvette sides. For absorption experiments, the light passes through the sample linearly, so only two sides need to be polished. For scattering and fluorescence experiments, the signal is collected at 90° to the light beam, so four sides need to be polished.
