Abstract: An automatic pipetting and analyzing device for the preparation and analysis of samples in the wells of a microtitration plate has a work platform on which positioning areas for auxiliary devices and a movement area for the sample plate are provided, a passive mechanical table without its own drive unit, the sample plate lying within the inner passive slide of the passive mechanical table, and an active mechanical table which is arranged above the passive mechanical table and by which a pipetting head can be moved in X-Y direction over the work platform in order to extract, transport and dispense liquids by at least one pipetting channel and in order to displace the sample plate by a coupling connection with the inner passive slide, for example, to place the sample plate in an incubator or to position it with the individual wells in an analysis device.

Abstract: An automatic tip changer for an automatic multichannel pipettor comprises a plurality of pipettes arranged in a pipetting head. Each of the pipettes arranged in the pipetting head is directly connected to a tip. A magazine which is outfitted with tips and lying in a magazine frame is pressed against the pipetting head. A supply carousel is provided for storing a plurality of stacking boxes in which magazines outfitted with tips are deposited. A lifting group which is arranged in a stationary manner relative to the supply carousel and the magazines are positioned successively in a mounting plane which is determined by the position of the magazine frame. A sliding group is included which is arranged in a stationary manner relative to the lifting group and by which the magazines are displaceable back and forth successively between the stacking box and the magazine frame.
