Pipetting errors are detected by: (a) during pipetting, measuring the pressure in the tip of a pipetting device and determining an earlier rate of change of the pressure in the tip; (b) based on the earlier rate of pressure change and a previous pressure value p, determining an expectation range for the pressure pat a further moment in time and/or an expectation range for the rate of pressure change &#x3b4;based on the pressure at the further moment in time t; (c) at the further moment in time tmeasuring the pressure pin the tip; and (d) determining the occurrence of a pipetting error by comparing the measured pressure pat the further moment tin time and/or a rate of pressure change &#x3b4;calculated on the basis of the pressure pat the further moment tin time.
