The cuvette is mainly used for liquid sample measurement. It usually works with spectral analysis instruments, such as spectrophotometer, hemoglobin analyzer, particle size analyzer, etc., for quantitative and qualitative analysis of substances. It can widely be used in many applications, such as chemical, metallurgy, medical, pharmaceutical, food, environmental protection, power plants, water plants, petroleum, and others. According to different materials, it is usually divided into quartz cuvettes and plastic cuvettes. Quartz cuvettes are widely used in various liquid measurement experiments and researches because of their good permeability in the wide wavelength range.
