Description

Technical Field

[0001] The utility model relates to the technical field of magnetic bead washing, and more specifically to a magnetic bead washing device. Background Art

[0002] Magnetic composite microspheres, magnetic microspheres and other nano-magnetic materials are compounded or group-modified with non-magnetic materials such as organic polymers, biomacromolecules, inorganic substances, etc. in a certain structure to obtain different magnetic composite products. These magnetic composite products are collectively referred to as "magnetic beads". In the preparation process of magnetic beads, a magnetic bead washing device is required to wash the magnetic beads to ensure that the performance indicators of the magnetic beads meet the standards.

[0003] Most existing magnetic bead washing devices achieve the purpose of cleaning by stirring with a stirring paddle at a fixed height. However, the stirring paddle can only stir at a specific position, and the longitudinal space of the stirring barrel is large. The stirring paddle cannot fully stir the magnetic beads at the top and bottom of the stirring barrel, so the cleaning effect needs to be improved.
