Abstract
The invention relates to a device for mounting pipette tips with a coupling element (4) that extends in an axial direction of the longitudinal axis (6). The coupling element (4) features a free end (8) from which a pipette tip (10) is deferrable to the coupling element (4) in an axial direction. Furthermore, the coupling element (4) features a gasket (21), at least one guiding element (25, 26), and a holding element (27). The gasket (21) consists of a flexible material which comprises an exposed sealing section (23) in an axial direction towards the free end (8) of the coupling element (4) against which a sealing section (43) of the pipette tip (10) can press axially. The guiding element (25, 26) is located on the outer side of the coupling element (4) and has the purpose of aligning the pipette tip. The holding element (27) is also located on the outer side of the coupling element (4) for interacting with holding agents (47) of the pipette tip (10).
