The Gold Standard for Sterility Assurance
Biological indicators (BIs) provide the only direct measure of the lethality of a sterilization cycle. The JPS Self-Contained Steam Biological Indicator contains a standardized, viable population of bacterial spores known to be highly resistant to steam.
If the sterilization cycle is effective, the spores are killed, and the subsequent incubation will show no color change. If the cycle fails, surviving spores will grow during incubation, causing the media to change color (usually from purple to yellow), clearly indicating a failure.
Key Advantages
Direct Lethality Test
Proves the cycle actually killed highly resistant spores, not just reached a temperature.
Self-Contained System
Includes spores and culture media in one vial, minimizing handling errors.
Easy Interpretation
A clear color change in the media indicates a failed cycle after incubation.
Built-in Chemical Indicator
The label on each vial has a chemical indicator to show it has been processed.
Incubation Options
Available in standard (24-48 hours) or rapid readout formats depending on your incubator.
Compliance Guarantee
Essential for load release of implantable devices and routine sterilizer qualification.
Product Features
- High Reliability: Utilizes Geobacillus stearothermophilus spores (ATCC 7953).
- Self-Contained Design: Reduces the risk of post-sterilization contamination.
- Clear Results: Easy-to-read color change in the media indicates spore growth (failure).
- Fast Readout Options: Standard (24/48 hr) and rapid readout versions available.
- Standard Compliance: Strictly meets ISO 11138 standards for biological indicators.
