Bionova® Spore Strips for Dry Heat, Steam and Ethylene Oxide
Sterilization Indicators
Spore strips biological indicator for steam, ethylene oxide and dry heat sterilization processes. Geobacillus stearothermophilus (ATCC® 7953) 10⁶ and Bacillus atrophaeus (ATCC® 9372) 10⁶ spores per strip. Readout time 24/48 hours. It is suggested the use of Bionova® MC1020-2 culture medium.

  • Consistent and reliable spore population and D-value
  • Envelope size: 25×70 mm non-absorbent material package
  • Spores carrier inside: 5×25 mm filter paper strip
  • D-ValueSTEAM: Not lower than 1.5 minutes. Conditions: 121 °C
  • Z-ValueSTEAM: Not lower than 6 °C
  • D-ValueEO: Not lower than 2.0 minutes, Conditions: 600 mg/L EO (100%), 60% RH, 54 °C
  • D-ValueDRY HEAT: Not lower than 2.0 minutes, Conditions: 160 °C
  • Z-ValueDRY HEAT: Not lower than 20 °C
  • Shelf-life: 2 years
  • Separate culture medium is required
  • Culture medium MC1020-2 (VWR# 77506-994) and incubation in Bionova dual incubator IC10/20 recommended (VWR part 77506-948)

Designed to control steam (Steam), Ethylene Oxide (EO) and Dry Heat (DRY) sterilization processes. Spore strips should be incubated in an appropriate growth medium for the corresponding Geobacillus stearothermophilus ATCC® 7953 or Bacillus atrophaeus ATCC® 9372 growth. It is suggested the use of Bionova® MC1020-2 for growth of both spores, selective according to the incubation temperature (Geobacillus stearothermophilus 60 °C/Bacillus atrophaeus 37 °C).

If the sterilization process was not successful, MC 1020-2 growth medium will turn to yellow after incubation at the corresponding temperature, thus indicating the existence of living spores on the strips.

If the sterilization process was successful, MC1020-2 indicating medium will remain its original color. A final readout should therefore be performed after 24 hours of growth medium incubation at 60±2 °C for steam sterilization processes control, or 48 hours at 37±2 °C for Ethylene Oxide and Dry Heat sterilization processes control.

T = 10 to 30 °C, RH = 30 to 80%
