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.

First claim

The invention claimed is:

1. Pipetting apparatus ( 1 ), in particular for pipetting a fluid sample ( 9 a ) by aspiration into a pipetting container ( 9 ) by means of air ( 9 b ) under a pipetting pressure, said pipetting apparatus comprising the following
a valve arrangement ( 10 ; 100 ; 200 ) having at least one valve device ( 101 ; 102 ; 101 ″) for setting a pipetting pressure, wherein the valve device comprises a valve chamber ( 106 ; 106 ′; 106 ″);
at least one pum…
