Pipette

A pipette, comprising a pipette casing (2) which has disposed therein, a seat (4) for the mounting portion (5) of a syringe cylinder (8) of a syringe (6), a piston seat (11) in an accommodating body (10) for a syringe piston (12) of the syringe (6), mounting devices (19, 28) for reversibly fixing the mounting portion (5) and syringe piston (12) within the seats (14, 11), and piston adjusting devices (15) for displacing the accommodating body (10) within the pipette casing (2), wherein the mounting portion (5) and syringe piston (12) are adapted to be axially slid to their mounting positions through axial apertures (7, 13) of their seats (4, 11), the mounting devices (19, 28) have radially advanceable gripping devices for fixing the mounting portion (5) and syringe piston (12) in the mounting positions, the gripping devices have syringe gripping levers (19) pivotally supported within the pipette casing and piston gripping levers (28) pivotally supported within the accommodating body (10), the syringe gripping levers (19) and piston gripping levers (28) are configured to have two arms including a gripper arm (21, 30) and an actuator arm (23, 31), the syringe gripping levers (19), at the insides of their actuator arms, have contact points (25) which when their actuator arms (23) are actuated are adapted to be externally pivoted against the actuator arms (31) of the piston gripping levers (28) and actuate the piston gripping levers (28), the syringe gripping levers (19) have inwardly projecting release levers (33) on the actuator arms (23), a transfer element (35) which is slidably guided transversely with respect to the release levers (33) within the pipette casing (2) in at least one guide (37) is adapted to be brought into abutment against the two release levers (33) by being shifted by a front-end sided abutment area (40) within the guide (37), and a trigger (46) displaceably disposed within the pipette casing (2) which is coupled to the transfer element (35) to displace the transfer element (35) within the guide (37) upon displacement of the trigger (46).
