Ethylene Oxide Sterilization Machine

The ETO Sterilization Machine is the most widely used sterilizer for disposable plastic medical devices.
ETO gas penetrates deeply into the packaging and materials, making it suitable for heat-sensitive, humidity-sensitive, and complex-structured products.

Main Features

• Low-temperature sterilization (37–55°C), ideal for plastic products like syringes and infusion sets

• High penetration ability, effective even inside long tubes, narrow spaces, and multi-layer packaging

• Programmable PLC control with fully automated cycles

• Multiple safety systems for gas control, pressure protection, and leak detection

• Energy-efficient and cleanroom-compatible design

Typical ETO Process

1. Pre-conditioning – Heating and humidification

2. ETO gas injection

3. Exposure phase – Microbial kill

4. Vacuum removal and air washing

5. Aeration – Removing residual ETO to meet international standards
