3M Attest VH2O2 Tri-Metric Chemical Indicators
Chemical indicators that verify exposure time, temperature and vaporized hydrogen peroxide concentration during sterilization cycles.
The 3M Attest VH2O2 Tri-Metric Chemical Indicator is a monitoring strip used in sterile processing departments to verify that a vaporized hydrogen peroxide sterilization cycle reached all three critical parameters, exposure time, temperature and the amount of vaporized hydrogen peroxide delivered. Placing an indicator like this inside a wrapped tray, rigid container, sterilization pouch or other pack type, and at specific locations within a load, gives the sterile processing team a visual check that conditions inside the pack matched what the sterilizer's own instrumentation reported.
This kind of tri-metric monitoring is more informative than a single-parameter indicator, since it confirms the combination of factors needed for effective sterilization rather than just one variable in isolation. Chemical indicators are a routine, high-volume consumable in any facility running VH2O2 sterilization, used on every load or pack processed.
Hospitals, surgical centres and sterile processing departments are the typical buyers of this indicator strip.
