Abstract: A Dewar vessel (1) for automated cryosubstitution or low-temperature substitution is disclosed. The invention further discloses an apparatus (10) for automated liquid transfer for cryosubstitution or low-temperature substitution. The apparatus (10) encompasses a container (50) that encompasses at least one specimen holder (2) and at least one reservoir holder (20); and wherein a movable transfer container (35) for automated exchange of at least one liquid (42) between the at least one specimen holder (2) and the at least one reservoir holder (20) is provided.

Abstract: The device (1) for fast tissue processing for histological examination consists of a housing (2) that is covered by a transparent hood (70). A baseplate (3) divides the device (1) into an upper part (4a) and a lower part (4b). Several process chambers that are served by a transport mechanism (6) with holders (40) for tissue specimens are provided for on the baseplate (3). At least one reservoir (74) is provided for in the lower part (4b) of the device, which has a flow connection to at least one process chamber. An operating panel (76) allows the user to enter the appropriate data.

Abstract: In microtomes or ultramicrotomes, it is necessary to preset the specimen (14) onto the knife (16). In order to facilitate and automate this presetting operation, which is intended to guarantee the fastest and most accurate possible positioning of the knife (16) relative to the specimen (14), the spacing (13) between the trimmed surface (15) of the specimen (14) and the specimen holder (22) is ascertained and is transferred to the microtome or ultramicrotome (10). The spacing (13) is preferably ascertained in the trimming device (12).

Abstract: An apparatus for the polymerization of biological specimens in the context of cryosubstitution is disclosed. Also disclosed is the use of diodes having UV components for the polymerization of biological specimens in the context of cryosubstitution. A cooled chamber (6) is provided, in which at least one specimen carrier (2) having a biological specimen (4) is received. At least one diode (7), which emits light having UV components and is arranged in such a way that the light is directed onto the biological specimens (4), is mounted on a constituent part (9) of the cooling apparatus (5).

Abstract: An apparatus for controlling a microtome (2) and a cooling chamber (4) provided therefor is disclosed. Control is accomplished by way of a single control unit (12, 18) that integrates both operating elements (30) for the microtome (2) and operating elements (32) for the cooling chamber (4).

Abstract: The invention concerns a unit (2) for automatic delivery of specimen slides to a coverslipper (3). The unit (2) comprises a housing (27) in which a front panel (25) is provided. Also provided is a passage (20) in the housing (27) that is defined substantially by a first and a second cutout (21 and 23) in the first and the second side wall (22 and 24). A transfer position (8) for racks (4) is provided in the region of the cutout (21) in the first side wall (22), and a transport apparatus (9) extends out substantially from the transfer position (8) to beyond the cutout (23) in the second side wall (24).
