Advantages
E-Beam
E-Beam offers rapid sterilization, with most products receiving their dose in just minutes or even seconds. This speed translates to shorter turnaround times, making E-Beam ideal for fast-paced, high-volume operations.
E-Beam systems can process large volumes of products each day. When medical devices are packaged for optimal E-Beam compatibility, they can achieve superior throughput and often a lower overall cost than EO, which involves more handling and longer processing times.
E-Beam sterilization facilities are stable and long-lived, powered by clean grid electricity. They do not use or produce harmful chemicals like EO, making them a more environmentally friendly option. There’s no need for special handling or aeration processes, which reduces potential supply chain disruptions and improves reliability.
EtO
Probably the best part of EO for most users is that it is gentle on soft polymers such as PTFE (Teflon) and other specialty materials that frequently can be part of modern medical devices.
EO, especially when combined with modest amounts of heat and humidity is an incredibly penetrative gas that can be used to access all of the surface regions in most products.
Most high-volume EO facilities offer multiple chambers capable of processing numerous pallets at once. While the dwell and aeration times for EO are much longer than the processing time required for E-Beam, the highly parallel nature of a large EO facility does offer high levels of throughput.

Frequently Asked Questions About E-Beam & EO Sterilization
EO is a toxic gas and requires careful handling to ensure the safety of workers and the environment. Sterilized products must undergo aeration to remove any residual EO. E-Beam, on the other hand, is a clean process that doesn’t involve harmful chemicals or leave residues behind.
While EO is effective, it carries health risks due to its toxicity and the need for strict ventilation measures. E-Beam is a safer alternative, using only electricity and producing no toxic byproducts.
E-Beam sterilization is much faster, often taking just minutes. EO, by comparison, takes several hours because of the need for exposure and aeration time.
EO works well for materials sensitive to radiation, like certain fabrics and Teflon. E-Beam is ideal for most medical devices and materials, offering rapid processing without the need for chemical sterilization.
EO requires careful disposal of toxic emissions and has a higher environmental impact. E-Beam is more eco-friendly, as it uses clean electricity and produces no hazardous waste.
