| description | 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. |
