3M™ Attest™ Biological Monitoring Systems are true biological indicators, in self-contained indicator capsules. They enable checks on the biological reliability and performance of each steriliser without laboratory facilities and laboratory trained personnel.

• Self-contained, reducing the risk of false positives due to contamination
• Colour change gives clear unambiguous, visual indication of PASS or FAIL
• Time saving and results in 24 to 48 hours which require no interpretation
