3M 1261P Attest Biological Indicators (Blue Cap)

Biological indicators are the only method that indicates the sterilization process was effective and the spores were killed. A nonpathogenic but highly resistant spore, Geobacillus stearothermophilus, is used to provide a maximum challenge to the steam sterilization process. Self-contained biological indicators. Design provides a maximum challenge to various steam sterilization cycles. A spore burden beyond the average bioburden (germ count) provides an extra margin of safety. Optimized media promote rapid growth of spores. Definitive color change of the media indicates sterilization process ineffectiveness. Quick verification time of 24 hours versus one-week, mail-in services.
