Beschreibung
Zusammenfassung:	The present invention relates to a method for controlling a magnetic valve (3) and more particularly to a method for dispensing and/or aspirating a volume of liquid as well as to a corresponding dispenser/pipetting apparatus. The method for controlling a magnetic valve (3) comprises measuring a capacitance at/of the magnetic valve (3) and determining a position (P) of a plunger (14) based on the measured capacitance. The method for dispensing or aspirating a volume of liquid comprises controlling a flow of a system fluid (9) by means of a magnetic valve (3) located between a pressure source and a dispenser/pipetting tip, dispensing or aspirating a volume of liquid through an exterior opening of the tip dependent on the flow of the system fluid (9), wherein controlling the flow comprises determining a flow time in dependence of the volume of liquid to be dispensed or aspirated, and controlling the magnetic valve (3) according to the proposed method, wherein the magnetic valve (3) is held open for the duration of the flow time.
