Abstract
A plurality of samples in a moist medium are treated simultaneously in a microwave cavity. The samples are conducted into the cavity through apertures formed in an upper wall of the cavity. Each aperture is surrounded by a chimney configured to create a barrier opposing the propagation of microwaves from the cavity. The samples are introduced into receptacles which extend through the chimneys. Each receptacle can be supported on the chimney a lower end of the receptacle disposed within the cavity. Alternatively, the receptacles can be in the form of continuous tubes extending through upper and lower walls of the cavity in order to convey continuous flows of the sample.
