3M Comply VH2O2 Chemical Indicator Strip
An internal pack process indicator that turns from blue to pink to verify medical instrument exposure to vaporized hydrogen peroxide sterilization.
The 3M Comply VH2O2 Chemical Indicator Strip is used inside instrument packs as an internal process indicator that verifies exposure to vaporized hydrogen peroxide during sterilization. The indicator starts blue and changes to pink once it has been exposed to the sterilant, giving sterile processing staff an immediate, easy to interpret visual signal when the pack is opened at the point of use.
This kind of internal chemical indicator complements the biological indicator testing schedule many hydrogen peroxide sterilization programs already follow, offering a quick pack level check on every single load rather than only on scheduled test days. Facilities running vaporized hydrogen peroxide sterilization typically choose this method for instruments and devices that are heat or moisture sensitive and unsuited to standard steam autoclaving, making a reliable internal indicator an important part of confirming each individual pack was properly processed before instruments are released for patient use.
This strip is used daily by sterile processing technicians in hospitals and specialised reprocessing units running hydrogen peroxide sterilization cycles.
