Intended Use

The Celerity 20 HP Biological Indicator (BI) is intended for routine monitoring of the following sterilizer cycles: Lumen, Non Lumen, and Flexible Cycles of the V-PRO® Low Temperature Sterilization Systems. STERRAD® 100S Sterilizer (Default Cycle) Standard and Advanced Cycles of the STERRAD® NX Sterilizer Standard, FLEX, Express and DUO Cycles of the STERRAD® 100NX Sterilizer When used in conjunction with the Celerity HP Incubator for the Celerity 20 HP BI provides a fluorescent result within 20 minutes.

Device Story

Biological indicator (BI) for monitoring vaporized hydrogen peroxide (VHP) sterilization cycles; consists of Geobacillus stearothermophilus spores and nutrient media in a plastic vial. Device placed in sterilizer; after cycle, BI inserted into Celerity HP Incubator. Reporter enzyme produced by surviving spores reacts with fluorogenic substrate in media to produce fluorescent signal. Incubator detects fluorescence within 20 minutes. Used by healthcare personnel to confirm sterilization efficacy. Output provides binary result (growth/no growth) to verify sterilization process success; enables rapid release of sterilized instruments.

Clinical Evidence

Bench testing only. Performance validated via RIT testing (meeting >97% alignment with 7-day conventional incubation), resistance testing (D-value, survival/kill times), and simulated use testing in V-PRO and STERRAD cycles. All tests met acceptance criteria for growth inhibition and sterilization monitoring.

Technological Characteristics

Self-contained biological indicator; Geobacillus stearothermophilus spores (1.0-4.0 x 10^6/BI); fluorogenic enzyme-substrate detection system. Plastic vial packaging. Requires Celerity HP Incubator for automated fluorescence detection. Operates at 55-59°C. Includes VHP-sensitive chemical indicator ink.

Indications for Use

Indicated for routine monitoring of vaporized hydrogen peroxide sterilization cycles in healthcare facilities using V-PRO and STERRAD sterilization systems.

Regulatory Classification

Identification

Biological sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor adequacy of sterilization. The device consists of a known number of microorganisms, of known resistance to the mode of sterilization, in or on a carrier and enclosed in a protective package. Subsequent growth or failure of the microorganisms to grow under suitable conditions indicates the adequacy of sterilization. Physical/chemical sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor one or more parameters of the sterilization process. The adequacy of the sterilization conditions as measured by these parameters is indicated by a visible change in the device.
