ETO Gas Sterilization Equipment
ETO Gas Sterilization Equipment is a low-temperature sterilization system that uses ethylene oxide (EO) gas to eliminate microorganisms by disrupting their DNA and cellular metabolism. This technology is internationally recognized as one of the most effective sterilization methods for heat- and moisture-sensitive products, making it a standard solution in the medical device, pharmaceutical, and healthcare manufacturing industries.
Features
Low-Temperature Sterilization for Sensitive Materials
ETO gas sterilization is ideal for products that cannot withstand high temperatures, such as plastics, rubber, polymers, optics, and electronic components. The gentle process preserves mechanical strength, flexibility, and functionality.
Exceptional Penetration Capability
Ethylene oxide gas can penetrate sealed packaging, porous materials, narrow lumens, and complex assemblies, ensuring complete sterilization even in hard-to-reach areas where other methods fail.
A standard ETO gas sterilization cycle typically includes the following stages:
1. Pre-Conditioning
Temperature and humidity are adjusted to optimize microbial susceptibility and improve sterilization efficiency.
2. Vacuum & Gas Injection
Air is removed from the chamber, and ETO gas is introduced under controlled conditions to ensure uniform distribution and deep penetration.
3. Gas Exposure Phase
Products are exposed to ETO gas for a defined period, allowing complete microbial inactivation across all surfaces and internal structures.
4. Evacuation & Aeration
Residual ETO gas is removed through vacuum and aeration cycles, reducing gas concentration to safe levels before product unloading.
