Features
Why Choose Ethylene Oxide (EtO) Sterilization for Medical Devices
Ethylene oxide sterilization is one of the most reliable and widely accepted sterilization methods in the medical device industry. Compared with steam or radiation sterilization, Medical Device EtO Sterilizers offer clear advantages:
Low-temperature sterilization (25–65°C) for heat- and moisture-sensitive materials
Terminal sterilization capability, compatible with final sealed packaging

Excellent gas penetration, suitable for long lumens, porous materials, and complex structures
Broad-spectrum microbial inactivation, including spores, bacteria, viruses, and fungi
As EtO is a flammable and toxic gas, Riches integrates comprehensive safety designs into every medical device EtO sterilizer, including:
EtO leakage detection and alarm systems
Automatic door interlocks and pressure protection
Exhaust gas treatment and aeration systems
Emergency stop and multi-level safety interlocks
These features ensure safe operation for both personnel and facilities.
Residual Gas Control & Efficient Aeration
The system includes optimized aeration processes to reduce ethylene oxide residue levels, helping customers meet international safety standards while maintaining production efficiency.


Applications of Medical Device ETO Sterilizer
Disposable medical consumables
Catheters, tubing, and infusion sets
