Abstract

Pipettiersystem mit einer Pipettiervorrichtung und mindestens einer daran lösbar befestigten Pipettenspitze, mindestens einem Befestigungselement an der Pipettiervorrichtung, an dem die Pipettenspitze befestigt ist, einer Abwurfeinrichtung an der Pipettiervorrichtung, die ein axial bewegliches Abwurfelement zum Lösen der Pipettenspitze vom Befestigungselement bei einer Axialbewegung des Abwurfelementes und eine Antriebseinrichtung zum Antreiben der Axialbewegung des Abwurfelementes hat, und einem eine im wesentlichen axiale Antriebsbewegung der Antriebseinrichtung in eine Axialbewegung des Abwurfelementes übertragenden Zugmittel-Getriebe, Druckmittel-Getriebe oder Gelenk-Getriebe mit dem die Abwurfstange zumindest beim Lösen der Pipettenspitze vom Befestigungselement über einen geringeren Weg axial bewegbar ist als die im wesentlichen axiale Antriebsbewegung zurücklegt und eine die Kraft für die im wesentlichen axiale Antriebsbewegung übersteigende Abwurfkraft auf die Pipettenspitze ausübbar ist.

Figure 00000001
Pipetting system with a pipetting device and at least one pipette tip detachably fastened to it, at least one fastening element on the pipetting device to which the pipette tip is fastened, a discharge device on the pipetting device, which has an axially movable dropping element for releasing the pipette tip from the fastening element during an axial movement of the dropping element and one Has drive means for driving the axial movement of the ejection element, and a traction means gear, pressure medium gear or articulated gear which transmits an essentially axial drive movement of the drive means into an axial movement of the ejection element, with which the ejection rod at least when the pipette tip is released from the fastening element over a smaller distance is axially movable as the essentially axial drive movement and a dropping force on the pipettes that exceeds the force for the essentially axial drive movement is practicable.
