how long does eto sterilization tak.png

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

Sterilization time calculation (N20)
N20 Process:Use the nitrogen gas (100%EO+N2) to get more safety
PC:preconditioning room, AR:Aeration room
		single channel, no PC and AR	single channel, have PC and AR	double channel, no PC and AR	double channel, With PC and AR
