In order to understand the actual sterilization effect of this type of ethylene oxide sterilizer device, we chose a small desktop ethylene oxide sterilizer, its actual sterilization effect and the concentration of ethylene oxide in the environment during the process of sterilization for experimental observation. The results are reported as follows. The test material was EO-2 type ethylene oxide sterilizer, with a volume of 300L, which was divided into 4 layers and put into the carrier rack.
The working mode of the sterilizer was non-pressure type, and no vacuum treatment was needed in the sterilization process. Ethylene oxide for sterilization is a liquid ampoule preparation, each ampoule contains 20g of ethylene oxide, and the bio-indicator is a self-contained bio-indicator tube made of Bacillus subtilis black variant spores, which is used for simulating the field sterilization test.
