At what concentration is ethylene oxide used for sterilization?

Ethylene oxide is commonly used for sterilization because it effectively kills a wide range of microorganisms, including bacteria, viruses, and fungi. The concentration for ethylene oxide sterilization is typically in the range of 450-500 ml/L. This concentration is effective because it ensures that the gas penetrates the materials being sterilized while also reducing the risk of toxic residues that may be left if the concentration is too high.

In a sterilization process, achieving the right concentration is crucial for both efficacy and safety. If the concentration is too low, it may not adequately sterilize the items, while a concentration that is too high could lead to medical device damage or produce harmful byproducts. The chosen concentration of 450-500 ml/L strikes a balance, allowing for efficient sterilization while minimizing these risks. This is an important aspect of sterile processing in healthcare settings, where the safety of patients and the integrity of the equipment are paramount.
