Abstract: A microtome has a blade holder on which a blade is mounted, an anti-roll device for supporting a section preparation that has been produced by means of the blade, and a suction device by means of which the section preparation can be picked up by suction and carried off. The suction device has a nozzle, with an adjustably mounted nozzle body, and a suction channel. Provision is made that the anti-roll device is mounted on the nozzle body and is adjustable, in particular pivotable, together therewith.

Abstract: The invention relates to a method and device for the cross-referencing of identification (1) of tissue slice supports (2), for microtomised analytical samples still to be mounted thereon, with identification information (3) of a tissue sample holder (4) of a tissue sample (5) which is not yet microtomised. The conventional problem of cross-referencing is improved in a simple manner, whereby the identification information (3) for the tissue sample holder (4) is automatically detected when positioned in the microtome (6) and an identification (1) corresponding thereto is automatically transferred to at least one tissue slice support (2) and that tissue slice support (2), provided with the identification (1), is dispensed for application of the tissue sample slice at the moment when a tissue sample slice must be applied to a tissue slice support (2).

Abstract: A knife holder device for a microtome having a blade guard constituted as a pivotable bow, wherein, in a protective position, the blade guard is disposed on the side of the knife facing away from the sample at a distance such that access to the cutting edge is not possible. The blade guard can be positioned in three different defined positions and is provided with elements that have the following effects depending on the position: in the upper, protective position, simultaneous fixing of the position of the knife holder in the guideway; in the central, knife-holder-sliding position, accessibility to the knife holder with simultaneous release of the position fixture of the knife holder in the guideway; and in the lower, knife-changing position, free accessibility to the knife holder with simultaneous fixture of the position of the knife holder in the guideway.

Abstract: A method for disinfecting a microtome cryostat (1) comprises a defrosting phase (11), provision (13) of a vaporous disinfection agent (2) which acts upon the closed cryostat chamber (3) and a period of time (14) during which said disinfection agent (2) acts, and having an associated device for carrying out the method. According to the invention, fast and effective disinfection and rapid restarting of a microtome cryostat (1) is possible with secure drying, the temperature difference (?T1, ?T2) being produced after the period of time (14) in the cryostat chamber (3) whereupon the precipitated disinfection agent (2) is removed (18) to a cold area.

Abstract: A device and a method for disinfecting a microtome cryostat with introduction of a disinfection agent (3) into the cryostat chamber (2), action of the disinfection agent on the cryostat chamber, removal of the disinfection agent (3) by precipitation in a colder area (6) and drainage away from there. To enable such a microtome cryostat (1) to be disinfected several times per day without prolonged interruption of operation, a disinfection agent is used (3) that is effective below 0° C. and is introduced as a mist into the cryostat chamber (2) at below 0° C., the disinfection agent (3) being effective as a frost deposit in the cryostat chamber, wherein the frost deposit is displaced into a colder area (6) by sublimation and is converted to liquid by sporadic defrosting phases of this area (6) and thus removed.

Abstract: The invention relates to an apparatus for handling microtomized tissue samples (1) which are arranged on an object carrier (2) and are provided with a machine-readable code (3), with a reader (4) serving to detect the information of the code (3) and a controller (5) serving to convert the information for handling purposes.

Abstract: A knife holder device for a microtome having a blade guard constituted as a pivotable bow, wherein, in a protective position, the blade guard is disposed on the side of the knife facing away from the sample at a distance such that access to the cutting edge is not possible. The operability is improved and simplified and therefore safe operation is adequately ensured. This is achieved by constituting the blade guard such that it can be positioned in three different defined positions and is provided with elements that have the following effects depending on the position: in the upper, protective position, simultaneous fixing of the position of the knife holder in the guideway; in the central, knife-holder-sliding position, accessibility to the knife holder with simultaneous release of the position fixture of the knife holder in the guideway; and in the lower, knife-changing position, free accessibility to the knife holder with simultaneous fixture of the position of the knife holder in the guideway.

Abstract: A knife holder for a microtome has a plate arranged pivotably on its base member, which, in its functional position, covers the cutting edge of the knife and is spaced apart from the cutting plane towards the side of the knife holder remote from the specimen. The plate is also spaced apart from the knife holder on the side of the cutting edge of the knife. The plate precludes gripping of the cutting edge of the knife and a pivoting mechanism for the plate is coupled to a switch. When the plate is pivoted out of the functional position, the motor drive of the cutting movement is locked, or a brake precludes any movement of the knife slide or specimen slide. The plate preferably consists of a transparent material to permit observation of section removal in the functional position.

The unit comprises a treatment chamber (1), a device (2) for supplying and removing treatment agents (3, 3?, 3?) to and from the treatment chamber (1), and a control system (4) for the performance of the treatment. The aim of the invention is to develop the unit in such a way that the need to carry out different treatments is taken into account in an economical manner. Towards this end, at least one other treatment chamber (5) is provided, by means of which treatments can be carried out independently from the first treatment chamber (1), the device (2) and the control system (4) also co-operating with that other treatment chamber (5).

Abstract: The invention relates to a tempering device (1) for objects (2) located on the object carrier (3) of a microtome (4) of a cryostat (5) comprising an operating means supply (6) connected to a cooling device or a cooling and heating device (7) arranged on the object carrier (3), and a temperature control system. According to the invention, one such tempering device (1) is embodied in such a way that the operating means supply (6) does not hinder the work carried out on the microtome (4), and the accuracy of the cut is affected as little as possible. To this end, the operating means supply (6) is displaceably positioned in a guiding element (12) which is arranged on the guiding carriage (8) for the advancing movement (9) and the cutting movement (10) of the object head (11) and is oriented parallel to the direction of advancement (9), in such a way that it can be guided away from the object head (11).

Abstract: The invention relates to a knife holder for a microtome having a knife receiver for fixing and positioning a knife and a knife for the knife holder. The knife holder is ergonomic, the operation is made easier and safer, and the knife does not need to be changed as often. To this end, the knife receiver is constructed to accommodate a disk-shaped knife. The knife is given the shape of a regular polygon, whereby the edges are cutters. The knife receiver has an axle on which the knife can rotate such that the cutters can be positioned for cutting an object.

Abstract: The invention relates to a treatment compartment (1) for treating histological samples with treating agents (2, 2?, 2?). The treatment compartment (1) comprises a housing (3) with an inlet and outlet (4, 4?) for the treating agents (2, 2?, 2?), a rotatable retaining device (5) which receives the samples and a closable access opening (6) on the front (7). The aim of the invention is to improve a treatment compartment (1) of the above kind in such a way that it has a compact design and is easily accessible without the risk of the treating agents (2, 2?, 2?) emerging.
