[0002] A cuvette is an instrument used for spectral analysis in a spectrophotometer. It is generally a rectangular parallelepiped with a frosted glass bottom and two sides and a light-transmitting surface made of optical glass on the other two sides. The cleanliness of the cuvette in a spectrophotometer is one of the factors affecting the accuracy of the measurement. To ensure cleanliness, some users use cuvettes once during testing, while more users reuse them to save costs. This places high demands on the cleaning of the cuvette, and the structure and light transmission properties of the cuvette must not be damaged during cleaning. Therefore, correct and reasonable cleaning methods must be adopted. Alkaline solutions should not be used for washing, and hard cloths or brushes should not be used for scrubbing. Existing cuvette cleaning is usually done manually, requiring each cuvette to be cleaned one by one, which is time-consuming and labor-intensive, and has low efficiency. Utility Model Content
