摘要:
In an apparatus for microwave-assisted preparation of specimens, the microwave chamber for reception of specimens to be processed is embodied as a waveguide (3), in particular as a monomode waveguide, and is equipped with at least one opening (3a) for introduction of the at least one specimen (11) into the waveguide. A cooling circuit comprises a cooling means (8) adapted to cool the fluid (12), which fluid surrounds the at least one specimen and is separated from the cooling liquid of the cooling circuit, in the region of the at least one specimen (11) inside the waveguide. The opening (3a) can be sealed in microwave-tight fashion, by means of a closure means (7), during operation of the apparatus.
摘要:
In an apparatus for microwave-assisted preparation of specimens with a microwave generator (1), a microwave chamber for receiving specimens (5) to be processed, and a container arrangement (11) for a number of containers (9) for liquids, the microwave chamber is realized as a waveguide (2) that includes a first opening (7a) for introduction of a specimen (5) and a second opening (8a), preferably arranged at the bottom, through which a liquid container (9) is reversibly introduced into the microwave chamber while the specimen (5) is held stationary, until the liquid container thus introduced into the microwave chamber, and the liquid contained therein, surround the specimen (5).

摘要:
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.
摘要:
An apparatus for cryosubstitution or low-temperature substitution is disclosed. The apparatus encompasses a Dewar vessel (1) that is embodied with a neck. A chamber (5) for reception of at least one specimen is inserted in the neck (53). The chamber (5) is embodied with a heavy base (51) that is connected to a first thermal conduction rod (7). A platform (8) is provided at the end of the first thermal conduction rod (7) facing away from the base (51). An insulator (12) is provided above the platform (8) of the first thermal conduction rod (7).
摘要:
A knife holder (5) for a microtome for cutting samples (4a) is disclosed. The knife holder (5) encompasses several knives (2a, 2b) each of which defines a cutting edge (16). The knife holder (5) is arranged pivotably about a shaft (18); and the shaft (18) is arranged substantially perpendicularly to each cutting edge (16) of the knives (2a, 2b).

摘要:
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).
摘要:
A container (50) for an apparatus for automated cryosubstitution or low-temperature substitution is disclosed. The container is embodied as a cup (51) open at the top. The container (50) is subdivided into a first sector (52) and a second sector (53), at least one specimen holder (2) being arranged in the first sector (52) and at least one reservoir holder (20) in the second sector (53); and the container is arranged in the neck of a Dewar vessel (1).
