Positive results are reported immediately. This test uses spore strips to measure the effectiveness of sterility procedures. A decade ago, biological indicators (BIs) used a visual readout method to determine if a sterilization cycle successfully inactivated microorganisms. Your results will be mailed upon completion of the incubation period and kept on file in our laboratory. In-house studies show that our media features a higher spore recovery rate, providing for a more dependable test.Ī convenient way to monitor sterilizers in Physician, Dental and Veterinary Offices, as well as Tattoo and Body Modification Parlors: just expose the test strips in your sterilizer and mail them in the included prepaid envelope. Propper manufactures ready-to-use Tryptic Soy Broth (TSB) culture media which is specially formulated for use with biological indicators (BIs). 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. Pharmacopeia (USP) Guidelines.ĭuo-Spore® Biological Indicator Strips are prepared from suspensions of Geobacillus stearothermophilus and Bacillus atrophaeus and encased in a peel-open glassine pouch. Our culture media is manufactured in accordance with Association for the Advancement of Medical Instrumentation (AAMI) ST-79 recommendations and U.S. Duo-Spore® Biological Indicator Strips are certified for Species, Population, D-value, Z-value (as appropriate) and Expiry. For monitoring the efficacy of steam, ethylene oxide gas, chemical vapor and dry heat sterilization processes used in healthcare facilities, body modification parlors and industry.īiological monitoring is recommended weekly, but preferably daily, and with every load containing implants.
