Why 50% of Medical Devices Rely on EO Gas Sterilization
环氧乙烷 (EO or EtO) is a colorless gas known for its unique molecular instability. While this makes it highly reactive, it is precisely this reactivity that allows EO to penetrate deep into complex medical devices and disrupt microbial DNA through alkylation, effectively preventing reproduction and ensuring 100% sterility.
Low Temperature Efficacy
Ideal for heat-sensitive plastics, polymers, and electronic components that would melt or degrade in steam autoclaves.
Deep Penetration
EO gas excels at reaching the interior chambers and long lumens of devices, even when they are inside their final breathable packaging.
Broad Compatibility
Safely sterilizes everything from implantable heart valves and pacemakers to delicate fiberoptics and surgical wound dressings.
The Precision Gas Sterilization Process
To ensure maximum safety and effectiveness, the EO process follows a rigorous four-stage sequence within a sealed vacuum chamber:
1
Breathable Barrier Packaging: Products are sealed in Tyvek or medical paper, which allows gas diffusion while blocking microorganisms.
2
Preconditioning: Humidity and temperature are raised to “soften” the microbial cell walls, enhancing the gas penetration.
3
Gas Injection & Exposure: Under vacuum, EO gas is vaporized and injected, maintaining controlled concentrations for a specific “dwell time.”
4
Degassing & 通风: A series of nitrogen washes and air inbleeds remove residual EO, making the product safe for patient use.
