MATHESON Compressed Gas Notes
Gas Sterilization with Ethylene Oxide Mixtures The science of sterilization has been changing over the past few years. Gone is the necessity of lengthy exposures to high heat to insure effective sterilization. Heat and moisture-sensitive items, often ruined by long exposures to steam, can now be effectively and completely sterilized by the turn of a valve. T h e valve is on a cylinder of sterilizing gas called by different proprietary names, but consisting of Ethylene Oxide plus a n inerting non-toxic, non-flammable gas to render the total mixture either non, or less flammable. For most sterilizing purposes, Ethylene Oxide concentrations of 450 to 1000 milligrams per liter of chamber space will be sufficient to provide a 100% km.

Eductor tube
Mixtures The sterilizing mixture can be compounded in a number of ways to render the mixture more or less concentrated in Ethylene Oxide, or to have higher or lower cylinder pressure to suit the needs of the sterilizer function and design. The Matheson Compressed Gas Catalog lists sterilizing gas mixtures available from stock from all 3 Matheson plants. Special mixtures of any concentration of Ethylene Oxide are available from Matheson.

be rendered non-flammable. Convenient to handle. Easy storage. Gas completely removed by aeration; no residue. Noncorrosive.
Typical Applications Here are a few of the items that have been effectively sterilized with sterilizing gas containing Ethylene Oxide: Plastic bandages, polyethylene bottles, packaged catheters, penicillin, surgical sutures, blankets, leather, wool, cotton, nylon, paper, plastics, foodstuffs, glassware, airplane cabins, railroad cars and buses. We are equipped to supply sterilizing gases in regular or special formulations, in a variety of cylinder sizes. Our Sales Engineering Department will be glad to furnish further details and quotations concerning your needs. We will welcome your inquiries on gas sterilization. Ethylene Oxide In addition to sterilizing mixtures Matheson distributes Ethylene Oxide in quantities ranging from an 8 oz. Lecture Bottle to 400 lb. steel drums. Available from all three Matheson plants. Our Ethylene Oxide Bulletin gives Specifications and physical constants. Mail coupon for free copy.
