Abstract
A pipette device including a metering liquid receptacle designed to be filled, at least in part, with working fluid and which has a pipette opening as a first tapering of cross-section of flow, a pressure change device which is designed to change the pressure of the working fluid in the metering liquid receptacle, and a throttle point in a pipette duct designed to be filled with working fluid as a further tapering of cross-section of flow. The throttle point is arranged fluid-mechanically between the metering liquid receptacle and the pressure change device and is dimensioned in such a way that a ratio of a flow resistance of the pipette opening for dispensed metering liquid to a flow resistance of the throttle point for working fluid, which flows through the throttle point when the metering fluid is dispensed, is less than 0.5.
