Suction device for cutting wastes in a cryostatic microtome

摘要

The suction device according to the invention for cryostatic microtomes has a filter for the separation of cutting wastes from the suction air stream, and a device arranged following the filter for sterilization or disinfection of the suction air stream. For this purpose, the air stream is first heated and then exposed to a strong UV irradiation. In the subsequent two-stage cooling arrangement, the air stream is cooled down again to about the cryostat temperature and is conducted back into the cryostat. The filter for the separation of the cutting wastes from the air stream is preferably constructed outside the cryostat as a liquid container with a disinfecting liquid, so that the cutting wastes are disinfected in the disinfecting liquid. A contamination of the surroundings or of the internal space of the cryostat with disease germs is largely prevented.
