Biochemical analyzers are indispensable equipment in modern medical laboratories. They are used to detect various biochemical indicators in body fluids such as blood and urine, providing important basis for disease diagnosis. As one of the core components of biochemical analyzers, optical filters play a vital role in them.

Application
Biochemical analyzer: also often called biochemical analyzer, is an instrument that uses the principle of photoelectric colorimetry to measure a specific chemical component in body fluids. Due to its fast measurement speed, high accuracy, and small reagent consumption, it is now widely used in hospitals, epidemic prevention stations, and family planning service stations at all levels. The combined use can greatly improve the efficiency and benefits of routine biochemical tests.
Enzyme reader: It is a professional instrument for reading and analyzing the results of enzyme-linked immunosorbent assay (EIA) experiments. Through the enzyme-catalyzed color development coupled to the antigen or antibody, the concentration of the antibody or antigen to be tested in the sample can be judged by the depth of the color development, that is, the size of the absorbance value.
