3M Attest Biological Steam Indicators 24 Hour

The 3M Attest 1261 Steam Biological Indicator is a self-contained system for validating gravity displacement steam sterilization cycles at 270°F/132°C. With a 24-hour visual readout and integrated chemical and biological monitoring, it delivers fast, reliable confirmation that sterilization parameters have been met. The color-coded design and built-in Geobacillus stearothermophilus spore strip make it straightforward to identify results—purple to yellow indicates spore growth and sterilization failure, while the chemical indicator transitions from rose to brown/black after processing. Designed for seamless use with the 3M Attest Incubator 116, this indicator supports compliance and infection control standards in hospitals, clinics, and sterilization departments.
