Abstract

An arrangement and process for calibrating and/or equilibrating single-channel and multi-channel liquid handling devices, wherein a dispensing volume of a liquid is dispensed via the dispensing channels of a liquid handling device into a measurement chamber of a measurement chamber carrier, each measurement chamber being associated with a dispensing channel, and the individual measurement chambers are hermetically sealed successively relative to the environment and are connected to a pressure chamber under an operating pressure so that an equilibrium pressure occurs that is relevant to the respective dispensing volume.
