| 摘要 |
The invention relates to an apparatus (1) for wet chemical reaction simultaneously on a plurality of samples, each reaction taking place in a container (2) containing a sample and at least one reagent. The apparatus comprises means (50) for emitting microwaves into an application cavity (7), the application cavity (7) being a regular cylinder bounded by an upper wall (8), a lower wall (16) and a side wall (13). It exhibits an axis X and has, in its upper wall (8), a plurality of openings (3), each opening (3) has a size such that it allows introduction of a container (2) into the application cavity (7) and it is provided with a shaft (4), with a height H which is a function of the emission frequency of the microwaves and of the passage cross-section of the opening (3), in order to form an absorption barrier opposing the propagation of the microwaves out of the application cavity (7). The apparatus is intended for wet acid or alkaline treatment of samples for the purpose of dissolving, hydrolysis or mineralisation. <IMAGE>
