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: &#x2014;a valve assembly with at least one valve device for adjusting a pipetting pressure, said valve device having a valve chamber; &#x2014;at least one pump device which is connected to the valve chamber in order to generate a chamber pressure in the valve chamber; &#x2014;a pipetting channel which is connected to the pipetting container, and&#x2014;a bypass channel which is open towards the surroundings, wherein&#x2014;the pipetting channel and the bypass channel are each connected to the valve chamber; and&#x2014;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.
