MAGNETIC ATTRACTION MODULE, ROBOT INCLUDING SUCH A MODULE, AND METHOD FOR USING SUCH A MODULE OR SUCH A ROBOT ON MAGNETIC BEADS

摘要

The present invention relates to a magnetic attraction module (1) including: at least one permanent magnet (2); for each permanent magnet (2), a cavity (3) associated with said magnet (2) and located inside a pin including two ends, a first end of which includes a hole (4) for entrance into the cavity and a second end includes a cavity head (5), said two ends being connected by a side wall (6); means (7) for moving each magnet (2) in question, along a movement axis parallel to a movement direction (8), between two positions including one interaction position for which a portion of said magnet in question is housed inside the associated cavity thereof via the entrance hole of said cavity and is in contact with the head of said cavity, and a retraction position (10) for which said magnet in question is extracted from the associated cavity thereof via the entrance hole with respect to the interaction position thereof. The invention is useful for purifying a molecule of interest on magnetic beads.
