Technical Field

[0002] The optical detection of biochemical detectors includes ultraviolet spectrophotometers. As a mature optical detection technology, ultraviolet spectrophotometers can be well integrated with other detection modules in biochemical detectors. It can analyze biological samples from different angles by sharing light source systems, sample processing and transportation systems, data processing systems, etc., thereby improving the versatility and detection efficiency of the instrument. Ultraviolet spectrophotometers are widely used in biochemical detection and can be used for many projects such as enzyme activity determination, protein and nucleic acid purity identification and quantitative analysis.

[0003] The UV spectrometer detects biochemical detection liquid in the cuvette. The number of detection data is determined by the number of cuvettes placed in the cuvette rack. The operator replaces the cuvettes back and forth, resulting in poor continuous detection performance when the UV spectrometer processes a large number of cuvettes.
