BI-OK® biological Indicators are a reliable method to test steam sterilization cycles.

• Self-Contained biological indicator vials for steam
• Vials provide test results in 24 hours
• Vial design prevents premature activation and minimizes risk of breaking

Vials are inoculated with Geobacillus stearothermophilus spores to challenge steam sterilization. Use in steam test pack during cycle, after sterilization cycle activate media by crushing the glass vial with the vial activator and incubate at 57 °C. A color change in the media indicates spore growth and cycle failure.
