ABSTRACT:
A pipette has a preferably thermoplastic pipette shaft, for slipping on a likewise preferably thermoplastic pipette tip, has a slip-on section which opens at least slightly conically, and an attachment section which is formed on the lower end of the pipette shaft and onto which the slip-on section of the pipette tip is slipped. A sealing section which is made of an elastically-flexible plastic material which seals well with low withdrawal forces is provided on the attachment section. Furthermore, preferably, a fixing section is formed on the plastic material of the attachment section of the pipette shaft at a location that is axially offset relative to the sealing section. The sealing section of elastic-flexible plastic material is molded directly, retentively, on the preferably thermoplastic material of the pipette shaft.
