Indicator designed for reliable monitoring for ethylene oxide sterilization process when used in conjunction with an appropriate biological indicator incubator and life science/ industrial sterilization applications.

• 48-hour standard readout
• Self-contained design

This 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. Also verified with a readout or Reduced Incubation Time (RIT) of 48 hours under specific test conditions.
