The duration of ETO (ethylene oxide) sterilization can vary depending on several factors, including the size and complexity of the items being sterilized, the load size, the specific sterilization parameters being used, the use of the preconditioning room and Aeration room, the gas you use, double channel or single channel.

When you use bocon eto sterilizer, you can Refer to the following table
