Description

The 3M™ Attest™ Biological Indicator 1264-S (green cap) is designed for reliable monitoring for Ethylene Oxide sterilization process when used in conjunction with an appropriate Biological Indicator Incubator.

The Attest 1264-S design is comprised of a paper carrier inoculated with a standardized population of Bacillus atrophaeus ATCC® 9372 spores, a glass ampule 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 reddish-brown to green upon exposure to the ethylene oxide sterilization process. The recovery media will produce a pH color change from blue-green to yellow if viable spores are present and incubation conditions are correct. The Attest 1264-S is verified with a readout or Reduced Incubation Time (RIT) of 48 hours under specific test conditions. 3M recommends that the RIT for Attest 1264-S be validated by the end user in their system.
