  • Patent number: 4599216
    Abstract: The three dimensional movement of items to be exposed to microwave irradiation is facilitated by the apparatus of the present invention which provides for the turningly rotating exposure of such items to microwave irradiation. The microwave sterilization of items and fixation of eucaryotic cell specimens may be accomplished by such microwave irradiation. A kit of spore samples may be used to determine sterilization efficiency of particular microwave ovens.The apparatus for facilitating the exposure of items to microwave irradiation comprises a base; a plate having a substantially horizontal plane and being rotatably mounted on said base; a spit comprising an axis and being turnably mounted on said plate in a manner substantially axially parallel to the horizontal plane; a means for mounting items upon the spit; a means for rotating the plate in the horizontal plane while turning the spit with items mounted thereon and a means for determining a sterilization efficiency in said microwave oven.
