Abstract

The invention relates to a pipette with a body for receiving a displacement device, the displacement device comprising a displacement chamber and a movable boundary element for bounding a pipetting stroke of the pipette. The pipette furthermore has an operating element for setting the pipetting volume of the pipette by movement of the boundary element in the body and for performing a pipetting operation, the operating element being in operative connection with a piston movable in the displacement chamber of the displacement device. The pipette furthermore comprises a counter for displaying the set pipetting volume and a locking mechanism for locking and/or unlocking volume setting by the operating element. It is provided that, on actuation of the operating element, the operating element is configured to perform a pipetting operation, to transfer the locking mechanism into a locked position and to lock adjustment of the pipetting volume.
