Disinfection validation testing with Geobacillus stearothermophilus
Disinfection validation testing using spore strips with Geobacillus stearothermophilus
DioSpore Controller “closed germ-carriers”: Bioindicators with Geobacillus stearothermophilus
German guidelines by Robert-Koch-Institut (RKI), European norms as well as international standards recommend a reliable disinfection validation testing of H2O2 room disinfection procedures with spores such as Geobacillus Stearothermophillus. These spore strips are enriched with blood and also wrapped up in a special membrane in order to prevent operating errors and wrong results.
This microbiological method meets standard DIN EN 11138. 1-3 DioSpore controllers per 15m3 are recommended in order to achieve a gapless validation.
Advantages of disinfection validation testing with DioSpore-Controllers
- A risk of contamination for people who get in touch with the bioindicator is excluded for technical reasons
- The handling of the bioindicators is very easy due to the safe membrane technique
- Storage and transport of the bioindicators are uncomplictated
- The risk of recontamination after use is not possible. This leads to 100% safe disinfection validation results (“closed germ carriers”)
- The placing ot the bioindicators is self-explanatory as they can be put anywhere in the room (also beneath the ceiling through a prefabricated opening)
European certified disinfection validation
Easy, quick, reliable and safe disinfection validation without any risk of recontamination due to “closed germ carrier” concept
Clinically proven and scientfically tested validation method
Disinfection validation according to International standards and European norms
