100L-300L Large Capacity Cylindrical Autoclave Pulse Vacuum Sterilizer
This Pulse Vacuum Sterilizer uses pressure-saturated steam to sterilize the articles. Pulsating vacuum exhaust is used to eliminate the influence of cold air on temperature.
Finally, vacuum dehumidification combined with jacket drying is used to dry the articles. It makes use of the physical characteristics that pressure saturated steam can release a large amount of latent heat when condensing, so that the articles to be sterilized are in a high temperature and humidity state.
After a certain period of time, all bacteria and spore tissues in the articles are destroyed, so as to achieve the purpose of sterilization.
