Sterilization biological indicator VERIFY™ V24

temperaturemedical

Each indicator is completely self-contained, providing 10 -6 colony forming units (CFU) of Geobacillus stearothermophilus and an ampoule of specially formulated growth medium with a pH indicator. The Verify V24I Self-Contained Biological Indicator is designed to be sealed after processing, reducing the risk of contamination (and consequent false positives) and evaporation of growth medium. A chemical process indicator on each vial provides immediate proof of processing. Following incubation, a vivid color change of the growth media from orange to yellow and/or turbidity gives unmistakable evidence of microbial growth. If no microbial growth occurs, the media remains orange and clear (no turbidity). STERIS has validated a 24-hour incubation time for the Verify V24I Self-Contained Biological Indicator. Sufficient growth medium is provided for incubation up to 7 days, if desired. The HP Activator for VERIFY™ Self-Contained Biological Indicator (one step process quickly seals and crushes the vial preparing it for incubation) and the Incubator are sold separately.
