Hi Joanna

STERRAD is a hydrogen peroxide gas plasma sterilisation process. During
sterilisation the hydrogen peroxide is not a gas state, it is a plasma
state (the so-called fourth state of matter –
http://en.wikipedia.org/wiki/Plasma_%28physics%29). Sterilisation with
hydrogen peroxide plasma has quite different permeation and
sterilisation properties than gas sterilisation like EtO.

> Thanks for your reply Michael. I may have not have written it clearly enough, but my question about the Sterrad relates to whether, in Australia, the Sterrad is considered a gas steriliser. My colleagues and I have always understood that the term gas steriliser refers to processing using Ethylene oxide rather than hydrogen peroxide in a Sterrad. I’m interested to hear others’ views
