Hydrogen Peroxide Plasma - Cleaning and sterilization • Advantages and applications
Hydrogen Peroxide plasma is one form of plasma that is utilized in Thierry plasma systems. It is most often used for plasma cleaning and sterilization. Hydrogen Peroxide in liquid form is most known for its cleaning or bleaching properties. When an aqueous solution of Hydrogen Peroxide is dosed into a plasma machine vacuum chamber it evaporates and disperses. Due to the disinfecting properties of Hydrogen Peroxide it kills all bacteria in the chamber and on the surface thus completing one phase of the Hydrogen Peroxide plasma sterilization process. Once the pressure inside the chamber drops more and the particles become excited enough to ionize, the hydrogen peroxide gas turns into hydrogen peroxide plasma. During this part of the sterilization, the hydrogen peroxide plasma breaks down all of the genetic material of any bacteria into smaller molecules, eradicating them and any harmful by-products.
The Advantages and Uses of Hydrogen Peroxide Plasma Sterilization
Hydrogen peroxide plasma sterilization provides a safe, non-toxic method of sterilization. It is a dry, non-thermal process that is environmentally friendly and does not produce any harmful by-products. Objects that are sterilized using Hydrogen peroxide plasma are completely safe to handle right away because there are no chemical residues left over and the process is done using relatively low-temperatures. This process is most often used on devices or materials that can not endure high temperatures associated with many sterilization techniques associated with certain plastics, electrical devices and some metal alloys. Most commonly hydrogen peroxide plasma is used to sterilize medical devices such as catheters and surgical tools.
