Terminal
Sterilization

Terminal sterilization plays a critical role in ensuring that medical devices are free from microorganisms, including bacterial spores, to achieve a Sterility Assurance Level of 10-6. This process is essential for supporting infection prevention efforts and reducing the risk of healthcare- associated infections. For heat- and moisture-sensitive medical devices, low-temperature sterilization is a preferred solution for effective instrument reprocessing, ensuring microbial inactivation while preserving device integrity.

Low-Temperature Sterilization

STERRAD™ Systems represent a pioneering approach to terminal sterilization, using proprietary vaporized hydrogen peroxide gas plasma technology to rapidly and safely sterilize a wide range of medical devices. With over 20,000 STERRAD™ Systems in use worldwide, ASP has been a leader in low-temperature sterilization technology for more than three decades. STERRAD™ Systems are validated for use with a broad range of devices through medical device manufacturer collaboration.
