Why Manufacturers Use EO Sterilization for Complex and Heat-Sensitive Products

Manufacturers and research facilities need sterilization solutions that protect delicate materials while supporting reliable, efficient operations that comply with regulatory standards. Andersen Sterilizers offers an effective low-temperature method for processing heat- and moisture-sensitive products that may be damaged by conventional sterilization techniques. EOGas 3 Series sterilizers use Ethylene Oxide Flexible Chamber Technology (EO-FCT) to sterilize compatible products with complex designs, including catheters, scopes with long lumens, polymers, and sensitive electronic components. Its flexible chamber design accommodates multiple loads in a single cycle, delivering a practical option for processing medical devices, research materials, and specialized components.

Protecting Complex Devices and Sensitive Materials

Heat, moisture, and other environmental conditions can compromise the integrity and performance of delicate materials, adhesives, electronics, and specialized components. EO sterilization operates at low temperatures and penetrates accessible internal pathways that may be difficult for other sterilization methods to reach. This makes it particularly useful for compatible devices with long, narrow lumens, intricate geometries, and varied material compositions. When supported by appropriate process development and validation, EO sterilization can achieve the required sterility assurance while helping preserve product functionality and material integrity.

Andersen EOGas 3 sterilizers are compatible with:

• Multi-lumen assemblies and long lumens
• Polymer-based disposables
• Electronic surgical devices
• Fiber optics and imaging systems
• Drug-coated implants
• Plastics, cellulose and rubber materials
• Metals, paper, fabric and more

Efficient Sterilization with Reduced EO Use

The EOGas 3 Series uses up to 90% less EO than many traditional rigid-chamber systems. Depending on the configuration, the system uses just 10.5-gram or 17.6-gram EO cartridges. Facilities can also pair the EOGas 3 with an Andersen EO Abatement System, which eliminates more than 99% of EO emissions before they are released into the environment. Using a dry catalyst resin, the abator converts EO into biodegradable organic compounds, helping facilities significantly reduce emissions while supporting compliance with increasingly stringent environmental standards.

Reliable EO Sterilization for Manufacturing and Research

Whether processing medical devices, specialized instruments, prototypes, or research materials, facilities need a sterilization process that fits their products and operational requirements. The EOGas 3 Series provides a low-temperature option for compatible heat-sensitive products, while validated cycles, appropriate aeration, routine monitoring, and documented quality controls remain essential to reliable results. Andersen Sterilizers also offers field service and technical support to help maintain equipment performance and support dependable sterilization workflows.
