Ethylene Oxide Gas Sterilization

Low-Temperature Sterilization for Heat and Moisture Sensitive Devices

An **ETO sterilizer** uses **Ethylene Oxide (EtO) gas** to sterilize medical equipment and other sensitive materials that **cannot withstand high heat or moisture**. This gas effectively **penetrates packaging and complex devices**, eliminating **bacteria, viruses, fungi, and spores** at **low temperatures**.

**ETO sterilization** is crucial for items like **plastics, electronics, and complex surgical instruments**, requiring a **controlled cycle** of temperature, gas concentration, humidity, and time, followed by a critical **aeration phase** to remove residual EtO gas and ensure device safety.

Advantages for Healthcare Providers

• Material Compatibility: Ideal for materials that would be damaged by steam sterilization (e.g., polyurethanes, PVC, certain metals).
• Deep Penetration: Gas penetrates deeply into the lumens of complex catheters and intricate instruments.
• High Sterility Assurance: Achieves a high Sterility Assurance Level (**SAL**), confirming the elimination of all viable microorganisms.
• Safety Features: Modern machines include advanced leak detection and automatic gas disposal systems to ensure operator safety.
