Application

This test is used for direct inoculation to test critical areas inside of complex hollow instruments at the most difficult penetration location, to test sterility, where usual biological indicators cannot be inserted. The inoculation and the sterility test procedure afterwards is the only possibility to check sterilization inside of complex instruments and sealed areas. The test can be used for all types of steam, formaldehyde or hydrogen peroxide sterilization processes with the enclosed G. Stearothermophilus suspension. In addition the same procedure can be used for ethylene oxide and dry heat sterilization processes if B. atrophaeus suspension is purchased separately. All types of instruments may be tested.
This procedure cannot be used for routine monitoring but only for validation. For routine monitoring of complex instruments, batch monitoring systems (BMS) are recommended.
To check the efficacy of the sterilization procedure, the correct inoculation with a defined population at the worst-case location is necessary. It is important to validate quantitative recovery. Before sterilization. After sterilization the aseptical quantitative microbiological incubation and evaluation is necessary. This whole validation procedure shall be carried out
from an experienced laboratory.
