DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a microwave heating device and more it concerns novel arrangements for moving a container for materials to be heated between loading and heating positions.
DESCRIPTION OF THE RELATED ART
In analytical chemistry and in particular for the preparation of materials, preferably specimen materials, or for the transformation of initial materials into reaction products it is common practice to perform the treatment under heat and pressure (excess pressure) as the desired process can only be realized or improved or forced under these conditions.
In a device are described in the DE-A-39 33 992, by irradiation of a gas under pressure with long wavelength electromagnetic waves a shorter wavelength radiation is generated with which the initial materials are irradiated, or the initial materials themselves are placed under reduced pressure and are irradiated directly with the long wavelength electromagnetic waves. For this purpose there serves a device with a heating chamber surrounded by a housing on all sides and closeable in a sealed manner in which an initial material introduced into an open or closeable receptacle can be heated under reduced pressure which is generated by an air pump connected with the heating chamber (FIG. 1 and 4) or, in the case of a closeable receptacle, connected with the receptacle (FIG. 2 and 3 of this publication) by means of an evacuation line.
A device of the kind mentioned in the introduction can be found in DE 40 38 273 A1 in various configurations in which, for the purpose of opening a housing surrounding the reaction chamber, the side wall (FIG. 1), lid (FIG. 2) or base (FIG. 3) of the housing in DE 40 38 273 A1 is displaceable by means of a displacement device between the closed position and an open position. There is arranged, on the respective wall part of the housing which is to be opened, a mounting, e.g. a locating plate, for at least one specimen receptacle, so that the latter can be moved into the reaction chamber or out of it with the respective displacement movement of the wall part. Through this the placement and removal of at least one specimen receptacle in the reaction chamber or the housing is facilitated, but a special mounting for the at least one specimen receptacle is necessary. Also a simple positioning of the specimen receptacle(s) on the floor of the housing is not possible. Furthermore on account of the presence of the mounting device and also for further constructional reasons this known device is not constructed in a way that would allow the placing of the specimen material directly in the housing, i.e. without a special specimen receptacle. A further disadvantage of the known device is to be seen in that in the configuration with a liftable lid for the reaction chamber (FIG. 2) the accessability to the reaction chamber is very much restricted in the open position: although the lid is lifted from the housing, because of its position above the housing the accessability of the upper-side housing opening is made more difficult.
A device of the kind under consideration can be found in WO/93/22650 in several configurations, in which, for receiving several pot-like specimen receptacles, a mounting device is provided in the form of a rotor in a reaction chamber, whereby the specimen receptacle can be inserted, by a horizontal movement, between a positioning plate engaging below the specimen receptacle and a lid which engages above the specimen receptacle--with its upper side opening--thereby effecting closure. The latter lid is part of the mounting device, which remains on the mounting device upon removal of the specimen receptacle. With this known device it is necessary to manually grasp the specimen receptacle upon insertion or withdrawal from the mounting device, which is possible only with difficulty in particular after the material treatment if only on account of the increased temperature. Furthermore it must be taken into consideration that the specimen material must be inserted i
