– 3M Attest biological indicators that monitor the effectiveness of the steam sterilization process and provide results within 48 hours
– The self-contained BI for 250F/121C gravity and 270F /132C vacuum-assisted steam cycles consist of a Geobacillus stearothermophilus spore strip.
– Sealed glass ampule with growth medium and a bromocresol purple pH indicator system; brown color-coded cap with holes for sterilant penetration and a hydrophobic filter as a bacterial barrier and a chemical indicator on the label that changes from rose to brown when processed.
