Abstract
Method and apparatus for chemically fixating a plurality of tissue specimens in a multimode microwave oven. The tissue specimens are loaded in respective cassettes and then placed in radial alignment in a circular container that is filled with a fixation solution. Selective microwave shields such as metal disks with central apertures are located above and below the container which is then rotated on a turntable while being exposed to microwave energy in the microwave oven cavity. The shields are selected to provide a substantially uniform microwave field within the region occupied by the cassettes so that all of the tissue specimens are consistently and uniformly fixated.
