Ethylene Oxide Sterilisation

The treatment of medical devices by ethylene oxide (EtO) has been the principle method of sterilisation and has become industry standard.

Ethylene oxide processing involves products being exposed to the gas under vacuum in a sealed chamber.  This is achieved in three phases:

Phase 1 Preconditioning

Products are placed in a preconditioning cell that is designed to raise the core temperature, typically to 40-50 degree centigrade and controlled humidity.  This is the first step to optimise the sterilisation process efficiency.

Phase 2 Processing

Products are moved by automatic transfer into the main chamber where the ethylene oxide gas is introduced under vacuum for a predetermined dwell time.  This validated process is designed to deliver the required sterility assurance level in accordance with ISO11135.

Phase 3 Heated Aeration

In the final stage, the product is moved by automatic transfer into a preheated cell which uses circulated air to remove residual ethylene oxide within the products.
