Abstract:
1. An automatic pipetting and analyzing device for the preparation and analysis of samples in the wells of a microtitration plate, comprising: a work platform on which a free movement area for the microtitration plate and positioning areas for auxiliary devices are provided for preparing the samples; a mechanical table which can be positioned in X-Y direction in any manner in a lower horizontal plane over the work platform and which has a holder for the microtitration plate; a pipetting head which can be positioned in X-Y direction in any manner in an upper horizontal plane by a drive unit and which has at least one pipetting channel with a slip-on body for tips that can be lowered in Z-direction; a coupling pin being provided at the pipetting head and a cutout which is shaped as the inverse of the coupling pin being provided at an inner passive slide; and said coupling pin and the cutout can be joined together to form a coupling connection by which a driving force acting on the pipetting head in X-Y direction is transmitted to the inner passive slide.
