Engineered with People in Mind

Our quality features enable the convenience and durability needed to operate an autoclave with complete peace of mind. The fully jacketed chamber is constructed of long lasting 316L grade stainless steel with superior corrosion resistance. In addition, the generator and piping are constructed of stainless steel. The pneumatic valves are air pressure operated, reducing maintenance. They are safer and more reliable, eliminating the requirement for high voltage. In addition, if no buttons or switches are operated for four hours, the autoclave will switch to standby mode.

Safety is Our Top Priority

Door Safety

The doors are designed with independent mechanical and digital safety features that guarantee a safe working of the sterilizer.
