摘要：Repeating pipette has an injection inlet (5) for the fastening section of aninjector (6), a receptor body (9) with a piston uptake for the operation section of aninjection piston. There is a device (10) to push the receptor body away from the injectoruptake, and a device (13, 17, 22) to push the body towards the uptake, which has a gearrack (13) attached to the body, an operating element movable along an operating path(B), and a swivelling latch (22) mounted against it. This latch engages and moves a stepforwards with the teeth (14) of the gear rack when the operating element movesforwards. When the operating element moves back again, the latch disengages from thegear rack. There is a step length adjustment device (23, 27) to adjust the step length ofeach step forward, which has a movable restraining element (23) to keep the latch fromengaging with the gear rack. With increasing step length, a path limitation device (29, 29')controlled by the step length adjustment device (23, 27) increases the operating path (B)of the operating element (17), and decreases it with decreasing step length.
