3M Attest Biological Indicators
1262P
This 3M Attest Indicator is for 132 degrees C vacuum assisted or 121 degrees
C gravity steam sterilizers. It provides assurance of sterility by challenging
the sterilizer with quantifiable, highly resistant spores. Incubation is for 48
hours.
Biological indicators are used for load control monitoring which is the
process by which a load is monitored and released based on the result of a
biological indicator (BI) in a test pack. The self-contained (BI) for 121°
C (250° F) gravity/132° C (270° F) vacuum-assisted steam cycles consist of a
Bacillus 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.
After sterilization, the vial is "crushed" to join the growth media with the
processed spore strip. The BI is incubated for 48 hours for a visual change
readout. A color change to yellow indicates surviving spores and a positive
result.
