Description

Technical Field

[0001] The utility model relates to a suction tip mechanism, in particular to a suction tip mechanism for a chemiluminescence immunoassay instrument. Background Art

[0002] A chemiluminescent immunoassay analyzer utilizes chemiluminescence to perform immunoassays. Combining the high specificity of immunological methods with the high sensitivity of chemiluminescence, these instruments are used to quantitatively or qualitatively detect specific biomarkers. These biomarkers can include proteins, hormones, drug metabolites, viral antibodies, and more.

[0003] When a chemiluminescence immunoassay analyzer is working, a pipette and a tip are needed to cooperate with each other to transfer the markers to be detected to the analyzer for analysis. However, different detection markers on the market have different specifications of tips when detecting them. Therefore, traditional pipettes and tips are not fully compatible and have poor adaptability. To this end, we propose a chemiluminescence immunoassay tip mechanism. Utility Model Content
