Abstract: The invention further relates to a method for producing said pipetting device. The invention relates to a pipetting device, in particular for pipetting a fluid sample by suctioning into a pipetting container using air under a pipetting pressure, having the following:—a valve assembly with at least one valve device for adjusting a pipetting pressure, said valve device having a valve chamber;—at least one pump device which is connected to the valve chamber in order to generate a chamber pressure in the valve chamber;—a pipetting channel which is connected to the pipetting container, and—a bypass channel which is open towards the surroundings, wherein—the pipetting channel and the bypass channel are each connected to the valve chamber; and—the at least one valve device has a closure element with a closure surface which is designed such that the chamber pressure is distributed to the pipetting channel and the bypass channel in a metered manner by the valve device in order to generate the desired pipetting pressure in the pipetting channel. The invention further relates to a method for producing said pipetting device.
