Abstract: An apparatus for treating objects, in particular cytological or histological specimens, having multiple processing stations (2) and a transport device (4) for delivering the objects into and out of the processing stations (2), the processing station (2) comprising a container (3) for receiving liquids, in particular reagents, and for immersion of the objects or of the object holders (7) carrying the objects, is characterized, in order to increase the flexibility of the apparatus, in that an insert (8) that fits into the container (3) and reduces the maximum capacity of the container (3) is provided, a rack (7) that carries the object carrier (9) and serves for immersion into the container (3) being adapted in terms of its dimensions in accordance with the remaining volume.

Abstract: A method for treating objects, in particular cytological or histological specimens, for example in an automatic stainer, the objects being delivered, preferably on object carriers and in object carrier magazines, by means of a transport device to various processing stations, inserted therein, and treated in accordance with a selectable treatment program, is characterized by automatic monitoring of the processing stations, in particular of the reagents, definable parameters being taken into consideration in the monitoring.

Abstract: A method for treating objects, in particular cytological or histological specimens, for example in an automatic stainer or in a tissue processor, the objects, preferably on object carriers and optionally in object carrier magazines, being delivered by means of a transport device to various processing stations, inserted there, and treated in accordance with a definable treatment program, is characterized by a throughput optimization on the basis of minimal movement distances of the transport device.

Abstract: An apparatus for treating objects, in particular cytological or histological specimens, having multiple processing stations and preferably a transport device for delivering the objects into and out of the processing stations, is characterized in that at least one heatable reagent station (1) is provided as a processing station.
