E-Beam Sterilization

The steps to e-beam sterilization: 1. After product is received and checked in, boxes are loaded in a single layer on the carts. 2. Product passes through a curtain of electrons and is sterilized. 3. Product is released per ISO 11137/13485 & FDA guidelines and quickly returned to the customer.


How E-Beam Sterilization Works:

The e-beam is able to penetrate medical devices and pharmaceutical products in their final shipping containers. The e-beam inactivates microorganisms either by causing microbial death as a direct effect of the destruction of a vital molecule or by an indirect chemical reaction. Advanced electronics precisely control the use of electrons in the sterilization of medical devices and pharmaceuticals.

The process involves accelerating a beam of electrons to near light speed where it passes through a scan chamber and then transitions into a curtain of electrons. Materials moving through the chamber on a conveyor system are showered with these high-energy electrons, which penetrate the material with a precise, predetermined dose.



Who E-Beam Sterilization Is For:

E-beam sterilization is a safe, effective, and efficient processing technology used to sterilize a wide variety of disposable medical devices and pharmaceuticals. Processing at E-BEAM is the most cost-effective method for low to medium density products, but not a good fit for extremely dense materials.

As the largest contract electron beam provider in the U.S., we offer capacity for large volume processing and provide a team of experts to deliver support.


Advantages of e-beam over ETO (also referred to as EO, ethylene oxide, ethylene oxide gas):

    • E-beam provides quick-turn terminal sterilization with simple, clean, on/off technology. There is no carcinogenic gas needed and there are no residuals, so product is able to be immediately released for distribution.
    • E-BEAM Services is capable of handling any shipment size, from single boxes to multiple truckloads, and no expensive breathable packaging is required.

Advantages of e-beam over gamma:

    • E-beam provides quick-turn terminal sterilization with simple, clean, on/off technology. There are no radioactive sources needed, so there are no security, transportation or disposal concerns.
    • The supply of electrons will never be in danger of running out, unlike the source of gamma photons, Cobalt 60.
    • E-beam has a faster dose rate than gamma, so there is a reduced risk of product damage. E-beam can even be used on sensitive products like pharmaceuticals and tissue products.
