Abstract: The invention relates to a plunger rod (10) for a liquid transfer device (100), wherein the plunger rod (10) is of two- or multipart construction. The plunger rod (10) has a first plunger rod component (12), which is in operative connection with an actuating device (110) of the liquid transfer device (100), and a second plunger rod component (14). The plunger rod (10) further comprises a sealing seat (16) for receiving a sealing element (18) for the plunger rod (10), wherein a parting line (20) between the first plunger rod component (12) and the second plunger rod component (14) is configured such that the sealing seat (16) is free of parting line flash (22).
The invention further relates to a method for producing such a plunger rod (10) and a liquid transfer device (100), in particular a pipette (102, 104, 106) and/or a multichannel bottom part (108) for a pipette (102, 104), with such a plunger rod (10).
