Abstract: A covering device places cover glasses on object carriers. The object carriers are held in a holder in a position inclined relative to the horizontal. The cover glasses are placed on the object carriers by a rotational movement. A pivot pin of the segment that places the cover glasses on the object carriers is mounted so as to be horizontally displaceable, such that when the cover glasses are positioned, they press on the object carriers in a rolling motion to prevent bubbles from forming in the specimen being mounted.

Abstract: An apparatus for treating cytological or histological specimens has numerous treatment stations in the form of containers, and a transport device by which the specimens to be treated are transported and deposited in the treatment stations. The transport device has a pivotable unit that can be brought under the specimens while the specimens are being transported. This pivotable unit is provided with a suction underlay on which the specimens or specimen holders are deposited, and by which treatment fluids that run out of the specimens or the specimen holders are received. Carryover of liquid residues from one treatment container to the next is thereby greatly reduced. The individual treatment containers are provided with covers, and the pivotable unit is designed to remove covers. Since the treatment containers are covered for most of the time, evaporation of the treatment liquids and release of fumes is greatly reduced.
