Abstract
A pipette device comprising a plurality of multi-channels which are arranged in one or several rows or like a matrix in several rows and columns and which are connected to the tip of a pipette on the end side thereof. At least one separate micromembrane pump is associated with each pipette channel for dosed suction or discharge of fluids, said pump consisting of several disk-type microstructures which are placed on top of each other and between which a pump chamber is formed and wherein one of which is provided with a membrane which can be deformed by an actuating element. In order to provide an extremely user-friendly pipette device which can be constructed in a simple, economical manner, at least some of the micromembrane pumps of different pipette channels are connected to each other in a material fit and the micromembrane pumps of each of said pipette channels can be programmed separately from each other by means of an electronic data processing unit such that the dosing volume of each micromembrane pump can be adjusted separately.
