Abstract

Gegenstand der Erfindung ist eine Pipette mit einem aus vorzugsweise thermoplastischem Kunststoff hergestellten Pipettenschaft zum Aufstecken einer ebenfalls aus vorzugsweise thermoplastischem Kunststoff bestehenden Pipettenspitze die einen sich zumindest leicht konisch öffnenden Aufsteckabschnitt aufweist, mit einem am unteren Ende des Pipettenschaftes ausgebildeten Befestigungsabschnitt auf den der Aufsteckabschnitt der Pipettenspitze aufgesteckt wird, wobei am Befestigungsabschnitt ein aus elastisch-nachgiebigem, mit geringen Abzugskräften bereits gut abdichtendem Kunststoffmaterial bestehender Abdichtabschnitt vorgesehen ist und wobei, vorzugsweise, am Befestigungsabschnitt ferner axial zum Abdichtabschnitt versetzt ein am Kunststoffmaterial des Pipettenschaftes ausgebildeter Fixierungsabschnitt vorgesehen ist. Diese ist dadurch gekennzeichnet, daß der Abdichtabschnitt aus elastisch-nachgiebigem Kunststoffmaterial am vorzugsweise thermoplastischen Kunststoff des Pipettenschaftes unmittelbar festhaftend angeformt ist.

Figure 00000001
The invention relates to a pipette with a pipette shaft, preferably made of thermoplastic, for attaching a pipette tip, which is also made of preferably thermoplastic, and which has an at least slightly conically opening plug-on section, with a fastening section formed at the lower end of the pipette shaft onto which the plug-on section of the pipette tip is plugged is provided on the fastening section, a sealing section consisting of resilient, already well sealing plastic material with low pull-off forces and, preferably, on the fastening section further axially offset from the sealing section, a fastening section formed on the plastic material of the pipette shaft is provided. This is characterized in that the sealing section made of resilient plastic material is molded onto the preferably thermoplastic plastic of the pipette shaft in a directly adherent manner.
