Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung einer Pipette (10) mit einem Volumeninhalt von 1 bis 50 ml aus einem thermoplastischen Kunststoff. Ein im Wesentlichen zylinderförmiger Pipettenschaft (12) mit einem Innendurchmesser (d i ) und ein im Wesentlichen zylindrisch-becherförmig ausgebildetes Pipettenreservoir (16) mit einem Innendurchmesser (D i ) werden Im Spritzgussverfahren hergestellt, Der Pipettenschaft (12) weist einends eine sich zu einer Ansaug-/Austrittsöffnung (20) verjüngende Pipettenspitze (14) und andernends eine konische Aufweitung (18) auf. Das Pipettenreservoir (16) weist einen coaxial vom Boden des Pipettenreservoirs (16) abkragenden Ansaugstutzen (24) auf. Die konische Aufweitung (18) wird stirnseitig und coaxial mit dem Pipettenreservoir (16) verschweisst oder verklebt. Das Verhältnis der gesamten Pipettenlänge (L) zum arithmetischen Mittel der Innendurchmesser (d i und D i ) des Pipettenschafts (12) und des Pipettereservoirs (16) beträgt wenigstens 15.
