Spore strips

Brand Name:

Spore strips for hydrogen peroxide sterilization processes consist of bacteria spores inoculated on PET plastic carrier with the size of 6 x 38 mm and packaged in glassine envelopes. They are inoculated with Geobacillus stearothermophilus (# 7953) 10^6 CFU/carrier. For resistance determination there is no standard available. The D-value is determined in a resistometer and is specified in the certificate.

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.
