Abstract
A positioning aid for liquid handling devices with a horizontally movable holding device for adapter and microtitration plate is disclosed. The holding device has a flexible tube extending in a closed channel and compressed air can be applied to the tube. The channel has, at least in the area of sliding pins which are arranged so as to be pretensioned by springs, widened portions which widen in the opposite direction to that of the spring, so that the sliding pins remain in a rest position when the tube is in the pressureless state so as to enable manipulation of the adapter and microtitration plate without friction, but, when compressed air is applied, occupy a clamping position in such a way that the tube fills out the widened portions so that the sliding pins contact the microtitration plate without play and the microtitration plate, in turn, contacts the stops of the adapter which are located across from the sliding pins, and the adapter contacts the fixed stops of the holding device without play.
