Propper BI-O.K.® Self-Contained Biological Indicator for Vaporized Hydrogen Peroxide (VHP)
Propper BI-OK® Self-Contained Biological Indicators (SCBI) for steam is a biological indicator designed for validation and monitoring of sterilization process in steam sterilizers. The indicator can be used in hospitals, small healthcare clinics, dental offices, scientific and industrial facilities.
Propper BI-OK® Steam Indicators are designed for use with pre-vacuum and gravity-displacement sterilizers in standard sterilization cycles at 121oC, 132oC, 134oC, 135oC. The suitability of use in other cycles should be verified by the end-user.
The biological indicator has been validated using RIT (Reduced Incubation Time) protocol and provide reliable results within 24 hours of incubation. The 24 hours incubation time is also applicable to all BI-OK® Steam vials used in the Propper biological indicator challenge packs. Survival/Kill values are calculated according to a formula in USP and ISO 11138. In case of spore growth the indicator changes color from purple-blue to yellow.
