Abstract
Disclosed is a stacking device for stacking and unstacking plate-shaped objects such as titer plates. A magazine is provided to hold the titer plates and a support plate is provided beneath the titer plates. A clamping device is provided to hold the bottom-most titer plate or second titer plate from the bottom. The clamping device preferably has two opposing, horizontal clamping beams which are forced by means of springs against the respective titer plate and which can be moved synchronously away from the titer plate by a motor via a linkage. The clamping beams can also be rotated about a vertical axis so as to adapt to titer plates having different shapes.
