Automatic enzyme-linked immunosorbent assay (ELISA) is an instrument used for detecting biomolecules, mainly for determining the content, purity, and activity of biomolecules such as proteins and nucleic acids. It has the advantages of high sensitivity, fast detection speed, and easy operation, and has become an important tool for life science research and clinical diagnosis.

The PSI CRYETTE freezing point meter uses supercooling and thermocouples to accurately measure the freezing point of a solution. The supercooling phenomenon refers to the phenomenon where the temperature of a solution is below the freezing point without freezing.
