3M™ Attest™ Biological Indicators for 270°F/132°C Gravity Displacement Steam Sterilizers, 1261

• Biological indicator vials are easy to use and interpret with visual color readout in 24 hours
• Self-contained biological indicators significantly reduce possibility of contamination, minimizing false positives and assuring more accurate results

The 3M™ Attest™ 1261 Biological Indicator (blue cap) is designed for monitoring 132°C gravity displacement steam sterilization processes.

The presence of active Geobacillus stearothermophilus spores is detected by a visual color change (media turns yellow). The yellow color change indicates a sterilization process failure. The final readout of a negative result (media remains purple) is made after 24 hours of incubation.
