ABSTRACT:
A pipette includes a pipette body made of plastic material and a pipette piston made of plastic material that is also electrically conductive. The pipette is automatically received or discarded in a pickup device which has an electric transmission filament. A pipetting apparatus has a pickup device for receiving test containers, a pickup section for a microstandard plate, a pipette hopper, and a dosing device. For automatic pipetting, the dosing device receives the pipettes, conveys the pipettes while simultaneously changing the distance of the pipettes to the test containers, absorbs liquid through the pipette, conveys the pipettes while simultaneously changing the distance of the pipette to the microstandard plate, discharges the liquid, and finally ejects the pipette.
