A biological indicator (BI) is the most direct proof that a sterilization cycle has killed micro-organisms. It carries a known population of highly resistant bacterial spores. After the cycle, the BI is incubated: no growth means the spores were killed and the cycle met its target. Hospital CSSD departments, pharmaceutical plants, cleanrooms and laboratories use BIs for routine monitoring, after repairs, and for sterilizer validation.
What we supply
- Spore strips in glassine envelopes, for steam, dry heat and ethylene oxide (EO) processes.
- Self-contained spore ampoules for steam sterilization, which are incubated directly after the cycle.
- Indicators for vaporised hydrogen peroxide (VHP) decontamination of rooms, isolators and pass boxes.
- Matching chemical indicators, Bowie-Dick test packs and process indicator labels so one supplier covers your whole monitoring programme.
