Abstract: The invention relates to a handheld fluid transfer apparatus, more particularly a pipette or repeater pipette, and a laboratory system comprising the handheld fluid transfer apparatus, which comprises: a control apparatus, which comprises a data processor capable to execute a control program for controlling at least one electronically controllable function of the handheld fluid transfer apparatus using input data, a user interface device for receiving a user input, the user interface device comprising a motion sensor device for measuring motion data of the handheld fluid transfer apparatus and for providing at least one motion data sequence, which contains subsequently measured motion data, a motion data memory for storing the at least one motion data sequence, an evaluation device being configured to determine the input data in dependence on the evaluation of the at least one motion data sequence. The invention furthermore relates to a method for operating the fluid transfer apparatus or the laboratory system.

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.
