TISSUE PIECE TREATING APPARATUS

摘要

Provided is a tissue piece treating apparatus comprising means for automatically controlling that temperature of a treating liquid (5) or a molten paraffin (5') in a bath inside (2), which is detected by a temperature sensor (S), by feeding back that temperature to switch a heating mode and a cooling mode alternately. Further comprised are heating means for turning OFF an air-cooling fan (F) of an ultrasonic vibrator (6) and ON a plane heater (H) in a heating mode, thereby to transfer the heat generated by the ultrasonic vibrator (6) and the plane heater (H), to the bath inside (2), and cooling means for turning ON the air-cooling fan (F) of the ultrasonic vibrator (6) and OFF the plane heater (H) in a cooling mode, thereby to block the heat transfer from the ultrasonic vibrator (6) and the plane heater (H) to the bath inside (2). These means can suppress the excessive heating of a tissue piece (3) so that they can suppress the heating modification of the tissue piece (3).
