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).
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:
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 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:
An apparatus (1) for handling coverslips (20) for specimen slides (9) comprises a transport arm (8), a base block (3) mounted on the transport arm and having a having a notional center axis (3a), and at least two suction devices (4 and 5) carried by the base block (3), each suction device (4 and 5) having an end (4a and 5a) that comes into contact with a coverslip (2) and points away from the notional center axis (3a) of said base block (3). The base block (3) both removes a single coverslip (2) from a magazine (24), and deposits the removed coverslip (2) onto a specimen slide (9).
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:
A method for preparing a hydrous, cryopreserved sample that is enclosed in a sample container (1, 1a, 1b, 1c), in the case of which, at least sample material is introduced into the sample container; this is then sealed pressure-tight and subsequently cooled by a cryogen (8) in a temporal and spatial sequence, a sacrificial region (4) of the container contents (2) initially solidifying and, only subsequently thereto, the entire container contents solidifying. A sample container (1a) that may be preferably used in this case is designed to be tubular, sealed at both ends thereof, and to essentially have a U-shaped form.
