Description

The 3M™ Attest™ Biological Indicator 1262-S (brown cap) is a reliable and convenient biological indicator for validating and monitoring industrial and pharmaceutical steam sterilization processes.

The Attest 1262-S is a self-contained biological indicator. This design reduces testing time and eliminates the potential for cross-contamination associated with the culturing of conventional spore strips. The Attest 1262-S design is comprised of a paper carrier inoculated with a standardized population of Geobacillus stearothermophilus ATCC® 7953 spores, a glass ampoule containing recovery medium which includes a pH indicator dye, a plastic cap with filter,and a plastic vial. The biological indicator has a chemical process indicator on the label that will change from rose to brown upon exposure to the steam sterilization process. The recovery media will produce a pH color change from purple to yellow if viable spores are present and incubation conditions are correct. The Attest 1262-S is recommended for 132ºC (270ºF) vacuum-assisted and 121ºC (250ºF) gravity steam sterilization processes. The Attest 1262-S could also be used to monitor other steam sterilization processes, such as 134ºC (273ºF), with appropriate testing and validation by the end user. The suitability of the Attest 1262-S for monitoring any steam sterilization process must be verified and documented by the end user.
