Trust 3M Attest biological indicators for precise sterilization validation across your steam sterilization equipment. Compatible with vacuum-assisted sterilizers at 132°C and gravity steam systems at 121°C, these self-contained units provide definitive cycle monitoring. The integrated chemical indicator transitions from rose to brown during processing, while the spore strip remains sealed until post-sterilization vial crushing releases the growth medium. Following 48-hour incubation, a yellow color change signals the presence of resistant spores, confirming sterilization inadequacy. This bulk box of 100 indicators supports consistent quality assurance protocols in your facility.

• 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.
• Result verification time of 48 hours

NOTE: Do not use to monitor dry heat, chemical vapor (MDT Harvey® chemiclave) or ethylene oxide (EO) sterilization processes.
