Magnetic bead separation device with adjustable magnetic flux

Abstract

The invention relates to a magnetic bead separation device with an adjustable magnetic flux. The magnetic bead separation device comprises a micropore plate, a micropore plate support, a base and a magnetic rod, wherein the micropore plate is placed on the micropore plate support, and the micropore plate support is placed on the base. The magnetic bead separation device also comprises a floating support, a lifting actuating unit and an electric control module, wherein the magnetic rod is adsorbed on the floating support by virtue of magnetism; and the floating support is connected with the electric control module by virtue of the lifting power mechanism, and under the control of the electric control module, the lifting power mechanism drives the floating support to realize upward and downward movements of the magnetic rod. By adopting the magnetic bead separation device disclosed by the invention, the lifting power mechanism is controlled by the electric control module to drive the magnetic rod to move up and down, thereby realizing magnetic liquid separation, avoiding a plurality of times of miscellaneous operation of a mechanical arm, improving the stability and reliability of a system, and improving the working efficiency of an automatic work station.

Description

technical field [0001] The invention relates to a magnetic bead separation device, in particular to a magnetic bead separation device with adjustable magnetic flux, which is suitable for magnetic bead separation in biological detection automation workstations.

In the traditional magnetic separation method, when the ma...

AI Technical Summary

Problems solved by technology

In the traditional magnetic separation method, the manipulator needs to perform multiple operations, and the position of the container needs to be adjusted each time to make the magnetic beads be adsorbed, and the adsorption is concentrated at the bottom of the container, which is not convenient for the pipette to reach into the container to transfer the liquid. It affects the stability and reliability of the magnetic separation, and affects the performance and operating efficiency of the workstation
