Abstract
A microwave oven particularly suitable for laboratory analytical use is described. The oven is designed for chemical digestion and the drying of materials to very low moisture levels. The oven utilizes a rotating platform to move the material being subjected to microwave radiation through the oven chamber to ensure uniform contact of the microwaves with the material. Radiation mixers and radiation isolators are also used to disperse radiation in the oven and absorb excess radiation.
