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.
Abstract: The combination of a table and a table-type microtome has a base having an internal volume and a linear guide. A seating device is movably mounted on the base. The seating device is movable along the linear guide. A drive causes movement of the seating device relative to the base along the linear guide for height adjustment. A table-type microtome is arranged on the seating device. At least one appliance for the table-type microtome is arranged in the internal volume of the base and is operatingly connected to the table-type microtome.
Abstract: A cryostatic microtome has a cryostatic chamber, and a microtome arranged in the cryostatic chamber, and including a specimen holder and a knife holder. In order to maintain high dynamics with respect to temperature changes and thereby a rapid matching to changing specimen consistencies, a coolable specimen holder and a coolable knife holder are provided, so that both the temperature of the specimen holder and also the temperature of the knife holder are adjustable independently of each other. Sections of improved quality can be attained by the free and independent temperature adjustment of the knife and specimen.
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 during transport, and by which treatment fluids that run out of the specimens or the specimen holders are received. Carry-over of liquid residues from one treatment container to the next is thereby greatly reduced. The specimens or specimen slides are thereby fixed in the specimen holders so that noise during transportation is reduced. The individual treatment containers are provided with covers, and the pivotable unit is designed to remove covers.
Abstract: A microtome includes a suction system that is integral with a knife carrier, which opposes the rolling up of tissue sections upon themselves and ensures evacuation of waste sections immediately after their appearance in the region of the sectioning blade of the knife carrier. The knife carrier has a suction cavity that is arranged in the immediate vicinity of the sectioning blade and is connected to a source of vacuum or reduced pressure. A cover is pivotably mounted on the body of the knife carrier. The cover has a u-shaped cross section, opened downwards, and profiled to cover the suction cavity and partially cover the sectioning blade. The cover defines a narrow free space in a form of a channel extending parallel to the upper face of the body of the knife carrier to guide a flow of suctioning air exerted on the sections. A valve has a closed position and an opened position for regulating the flow of suctioning air through the narrow free space.
Abstract: Described is a process and an apparatus (10) for the production of thin sections which are cut off a specimen (16), by the use of a cutting blade (20) of a microtome (12), and then transferred to a liquid bath (40). In order to prevent undesired compression of thin sections (98) during the cutting operation, the thin sections (98) are transfer from the cutting blade (20) to the liquid bath (40) by flowing fluid from the cutting blade (20) to the liquid bath, wherein the liquid bath is disposed at a spacing from the cutting blade by a flow passage. The flowing fluid is selectively guided, by a change-over switching device (56), to the liquid bath (40) or to a waste container (52) so that good thin sections (98) are separated from unsatisfactory thin sections (98).

Abstract: A microtome (2) with a sample holder (51) for a sample (22) to be thinly sectioned and with a knife holder (12) for a cutting knife (10) is described, wherein the sample holder (51), for performing a cutting movement (arrow 54) relative to the knife holder (12), can be driven in a first spatial direction (arrows 54, 56) by means of a first drive device (53), and for performing a coarse adjustment and a section thickness adjusting movement in a second spatial direction (arrow 24) perpendicular to the first spatial direction (54, 56) by means of an electrical second drive device (50). In the vicinity of the cutting knife (10), for defined delimitation of the coarse adjustment movement of the sample holder (51) in the second spatial direction, a delimiting device (20) is provided, which is connected over control means (44), preferably an electronic control, with the electrical second drive device (50).
Abstract: A microtome has a frame structure in which an object holding member for holding an object to be thinly cut is movable with an oscillating movement by a drive device. The object holding member has a cutting thickness feed member and an object return member, the latter including a switch element disposed on the object holding member for oscillating movement therewith. The frame structure carries first and second abutments arranged at the respective end portions of the path of movement of the switch element which oscillates with the object holding member. The switch element is thus displaceable by co-operation with the first and second abutments between first and second positions respectively; when the switch element is in its first position the object holding member is in a position in which it is set back from the cutting plane while when the switch element is in its second position the object holding member is in a position of being advanced into the cutting plane for an object-cutting operation.
