Abstract

The invention relates to a pipetting apparatus, and a method for producing the same, comprising: —a valve arrangement having at least one valve device for setting a pipetting pressure, wherein the valve device comprises a valve chamber; —at least one pump device, which is connected to the valve chamber to generate a chamber pressure in the valve chamber; —a pipetting channel, to which the pipetting container can be connected, and; —a bypass channel, which is open to the surrounding environment; wherein the pipetting channel and the bypass channel are each connected to the valve chamber; —and wherein the at least one valve device is designed such that, to generate the desired pipetting pressure in the pipetting channel, the chamber pressure is distributed in a metered manner by the valve device between the pipetting channel and the bypass channel.
