STERIS Spordex Self-Contained Biological Indicator Ampoules

The Spordex® Self-Contained Biological Indicator (SCBI) Ampoule (NA500) is for use in monitoring common steam sterilization processes. The Spordex SCBI Ampoule (NA500) is manufactured and tested in accordance with ISO 11138. Each indicator is completely self-contained, combining a spore species (Geobacillus stearothermophilus) and a specifically modified soybean casein digest growth medium with pH indicators in a glass ampoule. Following incubation, a vivid color change from red/pink to bright yellow and/or turbidity gives unmistakable evidence of microbial growth. If no microbial growth occurs, the media remains red/pink and without turbidity. The ampoule has been validated for a 48-hour reduced incubation time to shorten holding time for product release.
