Working experience with a new vacuum-accelerated microwave histoprocessor. 
Methods of microwave and vacuum-accelerated fixation, dehydration, and paraffin embedding are described, using a new type of vacuum and temperature stabilizable microwave histoprocessor: MFX-800.  The whole histoprocessing cycle lasts 3.5-5.5 h, depending on the thickness of the tissue blocks.  Well-preserved structural detail, intense staining, and good antigen preservation were achieved with various tissues.  This new histoprocessing facility is recommended for routine pathology laboratories in speeding up their processing procedures.
