Abstract: The invention relates to methods and to pipetting apparatuses for detecting at least one performance state of the suction mechanism of a pipetting device used for pipetting. Such a method and such a pipetting apparatus each use an electronic control device, a suction mechanism which, amongst other things, has an electrically powered motor, a measurement device have a pressure sensor or a measurement device acquiring the motor current for characterizing the physical work which is performed by the suction mechanism, wherein the pipetting device can partly be provided with a resistance device by means of which, during the execution of the method, the mechanical, in particular the hydraulic, resistance of the suction mechanism against the physical work performed by the motor is increased, wherein the control device is configured to detect a performance state of the pipetting apparatus, to acquire at least one value of this measurement value in function of a defined movement of the piston element, to store the at least one value of this measurement value in the data storage device.
