Cuvettes are often made from glass, quartz, or plastic. The material used depends on the type of experiment being performed:
  • Glass and plastic
    These materials are good for visible light studies, but they aren’t ideal for measuring purity and concentration.
  • Quartz
    Quartz is transparent in both visible and UV light, so it’s a good choice for UV-light spectrum sample measurements. Quartz cuvettes can have an extended transmission range of 190–2,500 nm, but they can be more expensive than glass. 

Cuvettes are designed to allow light to pass through the sample, and the sides are often polished to maximize light transmittance. The path length of the light beam through the sample can vary from 1–2 mm to 10 cm, but it’s often designed to be 1 cm. For absorption experiments, only two sides of the cuvette need to be polished, but for scattering and fluorescence experiments, all four sides need to be polished. 

When filling a cuvette, it’s important to only fill it to 80% capacity. If the liquid is too close to the top, it could spill out and cause problems during measurements.
