Abstract

The invention discloses a cleaning device, a liquid draining device and a corresponding cleaning method. The cleaning device comprises a liquid draining unit used for discharging waste liquid from a reaction vessel. The liquid draining unit comprises a liquid draining needle, an extraction pump and an isolation chamber, wherein the liquid draining needle is used for extracting the waste liquid, the extraction pump is connected with the liquid draining needle through a liquid draining pipeline to provide extraction power for the liquid draining needle, and the isolation chamber is arranged on the liquid draining pipeline between the liquid draining needle and the extraction pump to cooperate with the extraction pump to adjust the extraction power provided to the liquid draining needle. By the way, the extraction power can be easily and conveniently buffered and adjusted, a low loss ratio of magnetic beads can be obtained, and a liquid circuit device is conveniently maintained.

Description

Technical field [0001] This application relates to the technical field of liquid circuits, in particular to a cleaning device, a liquid drainage device and a corresponding cleaning method. Background technique [0002] The immunomagnetic bead separation technology is a new separation technology that combines the high specificity of immunology with the unique magnetic response of magnetic beads. It is a specific and sensitive immunological detection method and antigen purification method. This technology has been widely used in cell separation, protein detection, immunological detection and microbiological detection. [0003] In order to separate the free non-target substance from the target substance bound by the magnetic beads, the reactants need to be magnetically separated and cleaned in a magnetic field. The cleaning process is to extract the supernatant waste liquid from the reaction cup in the magnetic field and then re-inject it The cleaning solution is repeatedly circulate...
