| abstract |
The invention relates to a pipetting device having tube (1), which has a opening (3) at one end for suctioning or discharging a sample fluid, and which can be operatively connected to a pressure generation means at the other end, wherein a first electrode (5) is formed on the pipetting device, which forms a measuring capacitor together with a second electrode (4') formed by at least one part of the sample fluid (4') that can be received in the tube (1), which measuring capacitor is operatively connected to a measuring unit, and which measuring unit is designed to determine a volume of the suctioned or discharged sample fluid (4') according to the capacity of the measuring capacitor. The invention also relates to a fluid processing system having a pipetting device of this type, as well as a method for determining a processed fluid volume during pipetting with a pipetting device of this type. The invention further relates to uses of this method. |
