Gamma Irradiation for Single Use Assemblies and Systems

Gamma irradiation is a fast and common practice to sterilize single-use systems for aseptic bioprocess applications. The process parameters are confirmed by dosimetry, and the method is compatible with most plastic materials (except for acetal, PTFE, and unstablized polypropylene). However, the process has to be validated to ensure the products reach desired sterility assurance levels (SAL) after irradiation. Often the validation documents and certification of processing (COP) have to be completed before material usage.


Sterigenics offer full sterilization services, its sterilization technologies include gamma irradiation, electron-beam irradiation, ethylene oxide, and autoclave (steam sterilization).  Customer solutions include Sterigenics GPS™, VeriCycle™ Automated Process, Verification, SteriPro® Consulting and Nelson Labs, etc.
