Electron Beam Sterilization

Electron Beam Sterilization, also known as E-Beam Sterilization

Electron beam (E-Beam) sterilization is a form of ionizing energy that is characterized by its low penetration and high-dosage rates. The beam – a concentrated, highly charged stream of electrons – is generated by accelerators capable of producing continuous or pulsed beams. As the product/material being sterilized passes the E-Beam, energy from the electrons is absorbed, altering various chemical bonds, damaging the DNA, and destroying the reproductive capabilities of the microorganisms. Sterigenics provides a portfolio of high-energy electron accelerators for industrial applications including the IMPELA(R) accelerator.

Electron Beam, or E-Beam Sterilization is Best Suited For

Low-density, uniformly packaged products
Polymer modification
Cross-linking/branching
Semiconductor enhancement
Customized dose ranges
Biologics and tissue

Key Benefits of E-Beam Sterilization

While most materials manufactured for use in sterile health care products are formulated for radiation stability, some materials – certain polypropylenes, for example – experience less breakdown and long-term aging effects as a result of E-Beam’s shorter exposure time. Other benefits include:

High-Speed, High-Capacity Accelerators
Sterilizes low-density, uniformly packaged products quickly and effectively
Dosimetric Dosing
Eliminates post-sterilization testing and expedites distribution logistics
Material Modification
E-Beam sterilization processing can be used to modify polymers, improve semiconductor switching speeds, and change or enhance many other material properties
