Abstract

A chemical sterilizer system for sterilizing items by vaporizing a liquid chemical sterilant in a sterilizing chamber. Pre-evacuation of the sterilizer chamber enhances the sterilizing activity. Sterilant is injected into the sterilizer chamber from a prefilled shot chamber. Subsequent to the exposure period, spent sterilant is condensed and fresh air is pumped into the sterilizer chamber from a vacuum pump. An automated valving system uses a minimal number of three-way valves and one or more two-way valves to control the fluid flow functions in the sterilization cycle.
