Abstract

A method for calibrating and controlling a pipetting device for metered liquid with a multichannel, automated micrometering unit. All of the channels of the pipetting device are calibrated using a camera which detects the expelled droplets of the liquid, so that the volume thereof can be determined by means of a control device. The method makes it possible to carry out a calibration of the individually dispensed liquid volumes in droplet form to a prescribed volume deviation with a different number of possibly necessary repetitions for each individual channel.
