Celerity™ 20 STEAM Biological Indicator for IUSS

The Celerity 20 STEAM Biological Indicator (BI) for IUSS is a fast read 20-minute BI used for monitoring and qualification testing of commonly used gravity immediate use steam sterilization (IUSS) cycles.

Per AAMI ST79:2017, BIs within process challenge devices (PCDs) should be used at least weekly, but preferably every day the sterilizer is used. This standard also applies to monitoring Gravity IUSS Cycles. Sterility assurance monitoring requires the use of products that are specifically validated for use in gravity IUSS cycles.

How the Celerity 20 STEAM BI for IUSS Works

After a gravity IUSS steam sterilization cycle (previously referred to as flash sterilization) the color changing process indicator on the vial cap will provide immediate proof of exposure in the autoclave. The glass-free BI, containing Geobacillus stearothermophilus spores, is then activated using an easy twist and flick motion, eliminating need of a second activator. The activated BI is then incubated using the Celerity STEAM Incubator with results in just 20 minutes.

Why the Celerity 20 STEAM BI for IUSS?

• Fast results and quick device turnaround with an industry leading 20-minute incubation time
• Uses the same incubator as the Celerity™ 20 STEAM BI
• Easy electronic documentation of lot numbers and expiration dates with scannable barcode
