Verify Biological Indicators

The Verify Self-Contained Biological Indicator (SCBI) is for use in monitoring common steam and ethylene oxide (EO) gas sterilization processes.

Each indicator is completely self-contained, combining a disc inoculated with dual spore species (Geobacillus stearothermophilus and Bacillus atrophaeus) and an ampoule of specifically formulated soybean casein digest growth medium with a pH indicator. The Verify S3060/S3061 SCBI is designed to be sealed after processing, reducing the risk of contamination (and consequent false positives) or of growth medium evaporation.

Chemical indicators on each vial provide immediate proof of processing. Incubation time for steam sterilization is 24-hours for ethylene oxide (EO) is 48-hours Following incubation, a vivid color change from deep blue/purple to bright yellow and/or turbidity gives unmistakable evidence of microbial growth. If no microbial growth occurs, the vial remains deep blue and without turbidity.
