Duo-Spore® Biological Indicator Strips
Duo-Spore® Biological Indicator Strips are prepared from suspensions of Geobacillus stearothermophilus and Bacillus atrophaeus and encased in a peel-open glassine pouch. The glassine pouch allows for exposure of the enclosed strip to the sterilant, without exposure to ambient air, moisture and potential contaminants, allowing for worry-free transfer to culture media after cycle completion.
