Sealed EO Sterilisation Vessels
Sealed EO Sterilisation Vessels are core components ensuring efficient sterilisation. Their airtight design locks in EO gas, maximizing penetration into complex packages and large cavities, guaranteeing thorough sterilisation of precision instruments and sealed final products. Operating at 25-65°C, they suit heat-sensitive materials like masks and polymer parts, preventing damage. Enabling sterilisation of final sealed packages, they cut secondary packaging, boosting efficiency and reducing contamination. Compliant with ISO 11135, they ensure safe gas containment and residue control, forming a reliable closed-loop for sterile, high-quality product production.
Features
Hangzhou Riches Engineering Co., Ltd. is one of the leading manufacturers and suppliers of sealed eo sterilisation vessels in China. With abundant experience, we warmly welcome you to wholesale durable sealed eo sterilisation vessels for sale here from our factory.

We provide 3D drawing design services.

Our ethylene oxide sterilizers integrate a complete system, including pretreatment, sterilization, a degassing chamber, an ethylene oxide scrubber, and ethylene oxide energy recovery, ensuring efficient operation throughout the sterilization cycle.
In terms of structural components, the equipment utilizes reinforced carbon steel U-shaped ribs, significantly improving the sterilizer's overall stability and durability, enabling it to withstand pressure fluctuations during the sterilization process and ensuring long-term reliable operation.
To ensure leak-tightness and safety, all gaskets and seals in contact with ethylene oxide gas are made of Teflon or silicone rubber. These materials offer excellent chemical and temperature resistance, ensuring an effective seal during the sterilization process and preventing ethylene oxide gas leakage. The door seal is made of nitrogen-filled silicone rubber, which offers excellent elasticity and sealing properties.

FAQ
1. Ethylene Oxide Sterilization
Ethylene oxide sterilization plays an invaluable role in protecting public health. Ethylene oxide (EtO or EO) is a colorless gas with a wide range of commercial applications, including sterilization of textiles, personal care products, medical devices, cosmetics, and fragrances.
2. Which type of radiation can be used to sterilize sealed medical devices?
Gamma irradiation is the most commonly used form of radiation sterilization for materials that are sensitive to the high temperatures of autoclaving but compatible with ionizing radiation. Exposure occurs when packaging is transported for a specified period of time near an exposed cobalt-60 radiation source.
3. What types of packaging materials can be sterilized with ethylene oxide?
Common materials compatible with ethylene oxide plastics: Many plastics, such as polypropylene, polyethylene, polycarbonate, and polyvinyl chloride (PVC), are compatible with ethylene oxide sterilization.
4. What is the difference between EO and EtO?
Ethylene oxide (also known as EO or EtO) is a low-temperature gaseous process widely used to sterilize a variety of healthcare products, such as disposable medical devices.
