A pipetting apparatus for pulsed pipetting of dosage liquids in small metered volumes of less than 2 μl with the aid of a modifiable-pressure working gas, the pipetting apparatus encompassing: - a pipetting conduit at least partly filled with working gas; - a pipette tip that furnishes a receiving space that is at least partly filled with working gas, that is pressure-communicatingly connected to the pipetting conduit, and that is accessible through a pipetting opening, so that by means of a modification of the pressure of the working gas in the receiving space, a quantity of dosage liquid received in the receiving space is modifiable through the pipetting opening; - a pipetting piston received in the pipetting conduit, movably along the pipetting conduit, for modifying the pressure of the working gas; - a motion drive system for driving the pipetting piston to move along the pipetting conduit; - a control apparatus for applying control to the motion drive system; and - a position detection apparatus for detecting the position of the pipetting piston and for outputting to the control apparatus the position signal representing the position of the pipetting piston, the control apparatus being embodied to apply control to the motion drive system in order to generate a pressure pulse - with respect to a reference pressure which exists in the pipetting conduit immediately before a pipetting operation begins and at which no fluid passes through the pipetting opening - in the pipetting conduit, on the basis of the position signal outputted by the position detection apparatus, in such a way that the position of the pipetting piston during the pulse follows a predefined target pipetting-piston position curve, the duration of the pipetting-piston motion for generation of the pressure pulse not exceeding 35 ms, characterized in that the control apparatus is embodied to apply control to the motion drive system in order to generate a pressure pulse on the basis of the position signal outputted by the position detection apparatus, in such a way that the position of the pipetting piston during the pulse follows a predefined target pipetting-piston position curve, wherein the control apparatus encompasses a data memory, in which a plurality of predetermined target pipetting-piston position curves is stored for pilot control, wherein, depending at least on the dosage liquid and on the quantity of liquid to be pipetted, one target pipetting-piston position curve is selectable from the plurality of predetermined target pipetting-piston position curves as an active predetermined target pipetting-piston position curve for the respective pipetting operation. - a pipetting conduit at least partly filled with working gas;
