Abstract
The invention concerns an automatic pipetting unit with a replaceable pipetting head. The pipetting head includes two head rails located on opposite sides. The pipetting unit also has two horizontal guide channels located in the interior of the pipetting unit for supporting the two head rails. Two frame-mounted, double-sided slider crank mechanisms are vertically arranged in the pipetting unit. Each double-sided slider crank mechanism includes two crank mechanisms each connected to a common articulated thrust joint by a thrust couple. The horizontal guide channels are formed in the articulated thrust joint and the crank mechanisms are connected indirectly to a head cover of the pipetting unit, so that with the opening and closing motion of the head cover the two slider crank mechanisms are moved between two end positions so that the pipetting head can be moved vertically between a lower end working position and an upper end replacement position.
