Geobacillus stearothermophilus spore suspensions (# 7953) are used to inoculate complex instruments, carrier material and to monitor the success of steam sterilization processes. This suspension can also be used to monitor hydrogen peroxide and low temperature steam formaldeyhde (LTSF) sterilization processes. However the D-value has to be determined separately.
A microbiological laboratory is required for evaluation.
The suspension is available with different populations. The spores are located in 40% ethanol/water.
