- The first FDA cleared CI for VH2O2 sterilization categorized by the FDA as a multivariable CI for chemical vapour sterilization that independently monitors the three critical variables of time, temperature, and VH2O2 concentration
- Detects failed VH2O2 sterilization cycles more accurately than any other CI tested*
- The most colour stable of all VH2O2 CIs tested* — won’t change colour before sterilization under ambient light
- Consistent blue-toward-pink colour change for all 3M chemical indicators for vapourized hydrogen peroxide
- Proprietary protective film helps prevent ink smear on surgical instruments
- Easy-to-read “accept” and "reject" zones
- *Competitive Type 1 and Type 4 VH2O2 CIs
The 3M™ Attest™ Vapourized Hydrogen Peroxide Tri-Metric Chemical Indicator is a Type 4 indicator as categorized by ISO 11140-1:2014. It is the first and only Chemical Indicator in the FDA’s newly-created multivariable indicator category for chemical vapour sterilization, as it independently verifies that the stated values of the three critical parameters of exposure time, temperature, and concentration of vapourized hydrogen peroxide have been met.
The 3M™ Attest™ Vapourized Hydrogen Peroxide Tri-Metric Chemical Indicator verifies that the stated values for the three critical parameters of exposure time, temperature, and amount of vapourized hydrogen peroxide have been achieved within a package or containment device (i.e. wrapped trays, rigid containers, sterilization pouches, and other types of packs) and/or at a specific location within the load or empty chamber. Upon exposure to vapourized hydrogen peroxide, the colour of the coated indicator strip progressively changes from blue toward pink along the strip. The progression of the blue to pink colour change along the strip is visible through a window with marked “REJECT” and “ACCEPT” zones. The extent of the progression depends on exposure time, temperature, and amount of vaporized hydrogen peroxide.
Suggested Applications
- For use as an internal pack monitor in vapourized hydrogen peroxide sterilizers. For more details, review the Instructions for use
