Geobacillus stearothermophilus spore suspensions (# 7953) are used to inoculate complex instruments, carrier material and to monitor the success of hydrogen peroxide sterilization processes. This suspension can also be used to monitor steam and formaldehyde sterilization processes. However the D-value for hydrogen peroxide and LTSF has to be determined at extra cost.

A microbiological laboratory is required for evaluation.

The suspension is available with different populations. The spores are located in 40 % ethanol/water.
