Abstract
In a pipette device comprising at least one pipette channel and at least one pump means, which cooperates with the pipette channel for suction and dispensed delivery of liquid, the pump means consists of two electrically driven micropumps each having one suction-side and one pressure-side connection, one of which is connected to the pipette channel via its suction side and the other via its pressure side. The pipette device thereby acts as an air cushion pipette and is preferably provided with current via solar cells.
