Biological indicators provide the best assurance of sterility by challenging the steam sterilizer with quantifiable, highly resistant Geobacillus stearothermophilus spores. The system includes Rapid Readout biological indicators, disposable test packs, an auto-reader and log books. Biological indicators are used for load control monitoring which is the process by which a load is monitored and released based on the result of a biological indicator (BI) in a test pack.
3M™ Attest™ 1291 Rapid Readout Biological Indicators for 132°C/270°F gravity displacement cycles
Self-contained BI for gravity displacement cycles consisting of a Geobacillus stearothermophilus spore strip; sealed glass ampule with growth medium and dual indicator system; blue color-coded cap with holes for sterilant penetration and a filter as a bacterial barrier; and a chemical indicator on the label that changes from rose to brown when processed. After sterilization, the vial is "crushed" to join the growth media with the processed spore strip. The BI is incubated for one hour in the 3M™ Attest™ 290 Series Auto-reader for a fluorescent reading.
