ETO sterilization is highly effective because ethylene oxide gas can penetrate deeply into complex structures and packaging, killing all microorganisms—including bacteria, viruses, spores, and fungi.
How the ETO Sterilization Machine Works
The ETO sterilizer typically performs four main stages:
1. Preconditioning
Controls temperature, humidity, and air circulation
Raises product moisture and temperature to improve sterilization efficiency
2. ETO Gas Sterilization
Chamber is vacuumed to remove air
ETO gas (pure ETO or ETO mixed with CO₂/N₂) enters the chamber
Gas penetrates packaging and kills microorganisms
Process is controlled by PLC to ensure accurate pressure, temperature, and exposure time
3. Aeration (Gas Removal)
After sterilization, multiple vacuum and ventilation cycles remove residual gas
Ensures safe ETO concentration before unloading
4. Final Aeration Room (Optional)
Some products require additional aeration in a separate chamber
Reduces residual ethylene oxide to regulatory safety limits
The ETO Sterilization Machine is an essential part of modern medical device production. With its low-temperature processing, deep penetration capabilities, and intelligent control system, it ensures safe, effective, and high-standard sterilization for a wide range of medical products.
