Cuvettes are essential elements in photometry and spectrophotometry, used to hold liquid samples during the analysis of light absorbance and transmittance. Available in different materials depending on the application, they ensure high precision and compatibility with a wide range of instruments. Optical glass cuvettes are ideal for measurements in the visible spectrum, quartz cuvettes are designed for analysis in both the UV and visible spectra, and disposable cuvettes made from high-quality plastic offer a cost-effective and practical solution for routine applications, eliminating the risk of cross-contamination.
