Duo Spore® Biological Indicators (BI) are prepared from Geobacillus stearothermophilus for steam sterilization and Bacillus atrophaeus for ethylene oxide (EO|EtO) and dry heat applications. Both bacteria are commonly used as biological indicators to ensure the effectiveness of sterilization processes. They can survive in extreme conditions, such as high temperatures and radiation exposure, making them useful for monitoring in all clinical and non-clinical settings.
