Gas Plasma (vaporized hydrogen peroxide) is a relatively new option that can provide low heat sterility cycles with none of the off-gassing concerns present with EtO. Gas Plasma (VHP) sterilization has, until now, been exclusively used by large manufacturers as the end line process for in-house sterilization.
