ethylene oxide sterilization

- Oct 25, 2018 -

Ethylene oxide sterilization equipment is the key equipment for the production of disposable medical equipment. The installation operation and use management have special requirements. Ethylene oxide is used as a sterilizing agent. Ethylene oxide is a broad spectrum. A sterilizing agent that kills various microorganisms at room temperature, including spores, Mycobacterium tuberculosis, bacteria, viruses, fungi, and the like.

Currently, medical devices are widely sterilized by using ethylene oxide. Ethylene oxide is a flammable and explosive toxic gas with a molecular formula of C2H4O. It has an aromatic etheric taste. The relative density is 0.884 at 4 ° C, the boiling point is 10.8 ° C, and its density is 1.52 g/cm 3 at room temperature. Under conditions, it is easy to volatilize into a gas, which can cause an explosion when the concentration is too high.

The advantages are: l can kill all microorganisms, including bacterial spores. 2 Sterilized items can be wrapped, packaged in their entirety, and kept sterile before use. 3 Relatively speaking, EO does not corrode plastics, metals and rubber, and does not cause yellowing and brittleness of articles. 4 can penetrate irregular shapes and sterilize. 5 Can be used for sterilization of items that cannot be immersed in disinfectant, dry heat, pressure, steam and other chemical gases.
