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.
• Monitoring 270°F/132°C gravity steam sterilization processes
• Use in conjunction with 3M™ Attest™ Biological Indicator Incubator 116
• 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.

Attest™ Biological Indicator for Steam 270ºF/132ºC gravity, 24 hour readout, Blue cap

3M Attest Biological Indicators that monitor the effectiveness of the steam sterilization process and provide results within 24 hours.
3M™ Attest™ 1261 Biological Indicators for 270°F/132°C gravity steam cycles.
Self-contained BI for 270°F/132°C gravity steam cycles consists of a Geobacillus stearothermophilus spore strip; sealed glass ampule with growth medium and a bromocresol purple pH indicator dye system; blue color-coded cap with holes for sterilant penetration and a filter as a 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 spore strip. The BI is incubated for 24 hours for a visual color change readout. A color change to yellow indicates surviving spores and a positive result.
