Vacuum Pump for Ethylene Oxide Sterilization
What Is Ethylene Oxide Sterilization and How Does It Work?
Ethylene oxide (EO or EtO) sterilization is a low-temperature chemical process used to eliminate bacteria, viruses, fungi, and other microorganisms from heat- or moisture-sensitive medical devices and equipment. It is widely used in the healthcare, pharmaceutical, and packaging industries due to its ability to penetrate complex devices and materials that cannot withstand high temperatures.
How It Works:
- Preconditioning: The items to be sterilized are placed in a chamber where temperature, humidity, and pressure are controlled to prepare them for EO exposure.
- Vacuum Phase: A vacuum pump removes air from the chamber to allow even EO gas distribution and improve penetration.
- Gas Introduction: Ethylene oxide gas is introduced into the sealed chamber at a specific concentration.
- Exposure: The load is exposed to EO gas for a defined period, during which the gas penetrates packaging and device surfaces to destroy microorganisms.
- Evacuation: After sterilization, the EO gas is removed from the chamber using vacuum and flushing cycles.
- Aeration: The sterilized items are moved to an aeration room or chamber, where any residual EO is eliminated before the items are safe for use.
