Spore discs

Spore discs for hydrogen peroxide sterilization processes are inoculated on discs with 7 mm diameter, available on different carriers. They are packaged individually in Tyvek envelopes or in bulk in a blister box. 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.
