Spore strips

Spore strips for steam sterilization processes consist of bacteria spores inoculated on filter paper with the size of 6 x 38 mm and packaged in glassine envelopes. They are available in two different populations, inoculated with Geobacillus stearothermophilus (# 7953):

  1. 10^5 CFU/carrier according to EN ISO 11138-1 + 3 and United States Pharmacopeia (USP).
  2. 10^6 CFU/carrier according to EN ISO 11138-1 + 3, USP and European Pharmacopeia (EP), that require a population of at least 5 x 10^5 CFU/carrier for steam sterilization processes.

A microbiological laboratory with sterile work bench is required to aseptically transfer the spore strips into the growth medium after sterilization.

The growth medium for optimized growth of Geobacillus stearothermophilus spore strips is also available from gke.
