Abstract
The invention relates to a device for simultaneous treatment in a wet medium of four samples contained in four flasks placed in a microwave application cavity, four microwave deflectors being placed inside the application cavity. According to the invention, each deflector is formed by a cylindrical surface that surrounds a fraction of the outside surface of the flask, which fraction lies in the range one-fourth to one-half and the deflectors are symmetrically disposed in pairs about the axis X of the application cavity, and they are disposed for the most part on opposite sides of planes containing the axis X and the two axes of the corresponding flasks, the concave sides of the four deflectors facing in alternating directions.
