Software Overview
Software controls the STERRAD® 100 Sterilizer to ensure the most
efficient sterilization process as well as ease of use and operator safety.
The software manages the sterilization process throughout the five
stages: vacuum, injection, diffusion, plasma, and vent. The software also
monitors pressure, temperature, and other factors to determine when to
move from one stage to another, what to adjust in the various stages,
and when to abort the process if there are problems. The software
controls the machine in the monitor state including the processing of
hydrogen peroxide cassettes.
