Microwave Research and Applications, Inc sells a microwave tissue processing oven for researchers and microscopists. The oven was developed in collaboration with the CNR Biological Imaging Facility at the University of California Berkeley.  MRA's True-To-Power™ power control system allows continuous power output from 0 to 650W.  Due to the extreme uniform microwave flux within the chamber, the processor does not require the traditional water load. The microwave tissue processor is compact and fits under laboratory cabinets.  See the system at Microwave Research and Applications Inc.
