Traditional Spore Strips

Crosstex manufactures Biological Indicators (BIs) for use in monitoring Ethylene Oxide (EO) and Dry Heat sterilization processes. Biological Indicator Spore Strips for monitoring EO and Dry Heat processes consist of:

  • An inoculated carrier, 7 mm x 38 mm spore strip, of Bacillus atrophaeus (Cell Line 9372)
  • Primary packaging of a white glassine pouch
  • Products are accompanied by a Certificate of Analysis and are certified with population, purity, and resistance characteristics (value, survival and kill where applicable)
  • A reduced incubation time of 48 hours for Dry Heat Sterilization and 72 hours for Ethylene Oxide (EO) sterilization have been validated when Crosstex Biological Indicator Spore Strips, Discs, Threads and Wires are used in conjunction with Crosstex Prepared Culture Media (GMBTB-100)
