The invention relates to a system for extracting analytes from a biological sample, which comprises: an electronic pipette (12) having pipette cones with a tip (21); a well holder (18a, 18b); a pipette holder (14) comprising: a base (34) into which each well holder can be inserted; a pipette bracket (36) in which the pipette (12) is inserted, movable relative to the base (34) between a first position in which the tips (21) of the cones are inserted into a well (62, 69) of the holder (18a, 18b) and at least one second position in which the tips (21) are outside said wells (62, 69); a recess (78) opposite the pipette cones (20) above the tips thereof when the pipette bracket (36) is in the first position, and facing the tips (21) of the pipette cones (21) when the pipette bracket is in the second position; and a magnetised part (16) removably inserted into the recess (78). |
