This process does not create toxic by-products nor dangerous heat levels and requires no special venting or piping. Many types of medical instruments and equipment can be safely and completely sterilized with this process.

    Service Philosophy Sterilizer servicing is limited to the service activities described in this guide. All planned and corrective maintenance activities must be performed by ASP or its authorized representative. Unauthorized repairs void the warranty. The Sterilization Cycle The sterilization cycle is automatically controlled by a programmed microprocessor that monitors operating parameters and controls each of the five stages of the cycle.
