Sterigenics U.S., LLC products

A form of electromagnetic energy characterized by its deep penetration and low-dose rates, Gamma irradiators are powered by Cobalt-60, effectively killing microorganisms throughout the product and its packaging with very little temperature effect and no residues. The amount of radiation received depends on the type of product and its dose requirements. Dosimetric release allows products to be processed, verified, and immediately released for shipment. Our exclusive ExCell® high-precision irradiator delivers precision dosing to within ±10 percent.

Electron beam (E-Beam) irradiation 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.

Based on a gas diffusion process, Ethylene Oxide (EO or ETO) is capable of sterilizing and rendering products free of viable microorganisms. Sterility occurs when an EO gas molecule reacts with and destroys the microbial DNA. The process requires the simultaneous control of four variables, but interdependent parameters: gas concentration, temperature, relative humidity, and time of exposure. EO sterilization effectiveness depends on its ability to freely diffuse through a product and packaging. All products must be placed in breathable packaging that allows gas to penetrate the sterile barrier and reach all surfaces of the device or product.
