Abstract
The invention relates to a laboratory apparatus (1) which comprises an electric drive (4), and which is equipped with a device (10) with at least one sensor (13) for detecting vibrations, oscillations or imbalances. Said device (10) fits together with a mating coupling located on the laboratory apparatus (1) by means of a coupling (11) located on said device. Once in the coupled position, the device is connected to the laboratory apparatus (1) or to the controller or to the drive of said apparatus, either wirelessly or via electrical contacts. If any vibrations, oscillations or imbalances occur, they are detected by the sensor (13), which is connected or wired to the closed- or open-loop control of the drive motor via the connection between the coupling (11) and the mating coupling (12), and which can switch off the drive motor (4) or change the speed thereof in the event of undesired or dangerous oscillations, vibrations or imbalances.
