Plasma Steriliser takes advantage of Plasma and Hydrogen Peroxide Vapour technology.

As an Sterilant, a hydrogen peroxide chemical is relatively non-toxic, however hydrogen peroxide is a strong oxidant and these oxidizing properties allow it to destroy a wide range of pathogens and it is used to sterilize heat or temperature sensitive articles such as rigid and flexible endoscopes. The biggest advantage of hydrogen peroxide as a sterilant is the short cycle time.
Whereas the cycle time for ethylene oxide (EtO) may be 10 to 15 hours, the reaction of Plasma and hydrogen peroxide vapour allows for a much shorter cycle time.
Some plasma sterilizers have a cycle time as short as 40~50 minutes. On the other hand, Plasma sterilizers have some drawbacks.
Hydrogen peroxide has some limitations because of a process called cellulosic; this is a process whereby hydrogen peroxide may be completely absorbed by paper products.
Nevertheless hydrogen peroxide offers significant advantages in terms of throughput as well as environment-friendliness as it decomposes to form oxygen and water thus leaving no long term residues.
