Abstract: 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).

Abstract: 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.
