ABSTRACT:
The invention relates to an automatic precision pipetting device. The inventive device comprises at least two cylinder/piston-type pumping units (1, 2), the rods of which are rotated by means of a common motor unit (MP). Moreover, the pumping chamber of each of the pumping units (1, 2) is connected to a circuit comprising, successively, a conduit that opens into a container of rinsing liquid (RL), three successive solenoid valves (EV1, EV2, EV3) and a portion of circuit which connects the second solenoid valve (EV2) with the pipetting means (AP). The larger pumping chamber is connected in the part of the circuit that provides the connection between the two solenoid valves (EV1, EV2) while the second pumping chamber is connected to the above-mentioned portion of circuit by means of a connector, said portion of circuit comprising a solenoid valve (EV3) which is disposed between said connector and the aforementioned pipetting means. The invention is suitable for reagent reconstitution, in particular, in an automatic analysis device.
