Medistri’s EO Sterilisation Validation Flow

An Ethylene Oxide (EO) Sterilization Validation is designed to assist the manufacturer in the development of a sterilization process that delivers the appropriate sterility assurance level and ensures repeatability for each product type developed.


All types of products, whether sterilised in-house or by a contract steriliser like Medistri, must be validated to ensure compliance with national and international standards.







The requirements for an EO Sterilization Validation are outlined in ANSI/AAMI/ISO 11135. Various AAMI TIRs also offer guidance in meeting the requirements of the sterilization standard.


As Europe’s largest independent contract sterilisation company, Medistri partners with our customers through the entire process of sterilisation validation from protocol generation to final report completion.
