[0002] Enzyme-linked immunosorbent assay (ELISA) is a special instrument for enzyme-linked immunosorbent assay (ELISA). It can be simply divided into two categories: semi-automatic and fully automatic. However, its working principles are basically the same. Its core is a colorimeter, which uses colorimetry to analyze the content of antigens or antibodies.
[0003] At present, the placement of the ELISA plate needs to be stable to avoid contamination between reagents caused by vibration. However, the existing ELISA plate is directly placed in the detection chamber, and the ELISA plate has a movable space in the detection chamber.

In addition, the detection chamber is in a groove shape as a whole, and the detection chamber and the analyzer housing are generally not easy to disassemble. In this way, it is difficult to properly clean the detection chamber after the detection liquid is spilled inside the detection chamber.
