Abstract

The invention discloses a magnetic bead cleaning and separating device. The magnetic bead cleaning and separating device comprises a base, a bearing disc, a cleaning assembly, a uniform mixing assembly and a separating assembly, and the bearing disc is arranged on the base and can rotate in the circumferential direction relative to the base. A cup base connected with a reaction cup is arranged onthe bearing disc, the cleaning assembly comprises a cleaning needle, and the cleaning needle is arranged above the reaction cup so as to inject and suck liquid into and out of the reaction cup; the uniform mixing assembly is connected to the lower part of the cup base and is used for uniformly mixing a mixture in the reaction cup after liquid injection; the separating assembly comprises a magneticpart, and the magnetic part is arranged on the periphery of the bearing disc so as to adsorb the magnetic particles in the uniformly mixed reaction cups. According to the technical scheme, the uniform mixing structure of the device is optimized, and the uniform mixing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automated biochemical analysis, in particular to a magnetic bead cleaning and separation device. Background technique [0002] In the automatic chemiluminescence immunoassay analyzer, magnetic particles refer to colloidal composite materials that can be uniformly dispersed in a certain base liquid. Because of its superparamagnetic properties, high specific surface area, and functional groups that can be modified. Therefore, antigens / antibodies, enzymes, nucleic acids / oligonucleotides, small molecule drugs, etc. are immobilized on its surface. The magnetic separation technology is to separate the magnetic particle complex and the reaction liquid for solid-liquid phase separation. In order to ensure the effect of magnetic separation, it is necessary to fully mix the reaction solution during the separation process, inject and absorb liquid and wash repeatedly to remove impurities, so as to obtain accurate ...
