A transmission module for transmitting torques having a base, a first drive shaft, a second drive shaft parallel thereto, a first output shaft and a second output shaft, both rotatable about a common axis, the axes of the drive shafts are arranged parallel to the axis of the output shafts, a gear unit, where the two drive shafts, the gear unit and the first output shaft are rotatably supported in the base, and the second output shaft is rotatably supported in the first output shaft and the gear unit is designed in such a way that a synchronous rotary movement of the two output shafts can be effected by a rotary movement of the first drive shaft and a relative rotary movement of the two output shafts can be effected by a rotary movement of the second drive shaft.

The invention relates to a pipetting apparatus () having a pipette tip () for aspirating and dispensing liquid samples; a pump () for generating negative pressure or positive pressure in the pipette tip () that is connected to the pipette tip () by means of a pump conduit (); a fluid chamber () defined by the pipette tip () and/or the pump conduit (); a measurement probe () functionally connected to the fluid chamber () for measuring the physical parameters resulting in this fluid chamber () during pipetting; and a device control system () with a processor (), in which an activated computer program product enables the control system () of the pipetting apparatus () to individually accept or reject pipetted liquid samples on the basis of the physical parameters measured. The pipetting apparatus () in accordance with the invention is characterized in that it comprises a data storage device () for storing an actual measured curve () measured during pipetting and a simulated curve () for such a pipetting procedure and also a computer program product that in an activated state enables the processor () of this pipetting apparatus () to generate this simulated curve () and approximate it to the actual measured curve () iteratively to create an iterative curve () and then matching the pipetting and/or the corresponding pipetted liquid samples to one of a plurality of decision-making criteria on the basis of sections of the measured curve () in the actual measured curve () that deviate from defined threshold values () in relation to the corresponding sections of the curve () of the iterative curve (). A corresponding computer program product and method are included within the scope of the invention.

A plate and method for positioning functional elements in a system for working with fluid-containing samples includes a horizontal work field having a lengthwise dimension and a perpendicularly extending transverse dimension, as well as a robot arm with a functional element, aligned essentially perpendicularly to the work field in a Z direction. The robot arm can move the functional element in at least a partial region of the work field in the X and/or Y direction. The plate includes two light barriers which intersect inside the partial region, each having a transmitter and receiver whose scanning or detection beams each extend in a direction deviating from the X direction and/or from the Y direction.
