ASP’s first vaporized hydrogen peroxide gas plasma sterilizer, the STERRAD^® 100 System received FDA clearance in 1993. This first-of-its-kind technology sterilizes medical devices by diffusing hydrogen peroxide vapor into the chamber and then electromagnetically exciting the hydrogen peroxide molecules into a low-temperature plasma state. The combined use of hydrogen peroxide vapor and plasma safely and rapidly sterilizes medical instruments and materials without leaving toxic residue.
