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.
