LISA provides the highest standard of sterilization while combining high temperature and pressurized steam for effective and efficient sterilization. Microprocessor-controlled precision guarantees the proper time and heat settings are utilized to ensure sterility. The pre-vacuum cycle evacuates contaminated air from the chamber. Then the vacuum pulls hot steam through all areas of the load. The load is then dried in a post-vacuum cycle to complete the sterilization process. An effective drying cycle is imperative to protect instruments from corrosion and to prevent re-contamination. Some sterilizers skip the drying cycle risking damage or re-contamination. The Lisa sterilizer dries materials in a post-vacuum cycle so the finished load remains sterile and corrosion is eliminated. Items are cool to the touch and can be safely removed for immediate use or storage.
