Biological Indicators

STERIS's wide range of high-quality biological indicators are designed for routine monitoring, product testing and qualification of steam, ethylene oxide (EO), and vaporized hydrogen peroxide sterilization processes. From self-contained biological indicators (SCBI) to challenge packs or test packs, these devices play a critical role in sterility assurance and provide the only direct measure of the lethality of the sterilization process.
