Abstract
The invention relates to a device for interchanging suction pipettes which can be removed from a magazine and coupled to a fitting head of a fitting device and detached from the fitting head and deposited in the magazine. The fitting head has, on its side facing the magazine, a motor on whose driven shaft a star-shaped part and a latching plate are mounted. The latching plate has at least one nub ( ) which, after insertion of the star-shaped part into a star-shaped cutout in the suction pipette held in the magazine and after rotation of the star-shaped part and the latching plate into a locking position, engages in a notch, and which, on insertion of a suction pipette held on the star-shaped part into the magazine, can be moved out of the notch. The magazine has, on the side facing the fitting head, a sliding ring which is arranged in a rotationally fixed manner in the magazine and into which the suction pipette can be inserted in such a manner that the star-shaped latching plate comes to rest with its outer edges on the sliding ring where it is raised resiliently away from the star-shaped part, so that the nub is situated above that surface of the suction pipette which faces the fitting head.
