The "Why" and "How" - Low temperature sterilization with the STERRAD™ Systems

Why do I need a Low Temperature Sterilization System in my hospital?

right arrow

Most medical and surgical devices are made of material compatible to high temperature and thus can undergo heat and primarily steam sterilization reprocessing. The last decades though has been a significant increase in the design and production of medical devices and instruments made of materials that require low temperature sterilization.

Among the different choices of low temperature sterilization technologies are systems using Ethylene Oxide (EtO), Formaldehyde (FO), Paracetic Acid (PAA) and Hydrogen Peroxide (H2O2).1

Some of these technologies are related to potential hazards to patients and staff as well as lengthy cycle times, higher costs and resources involved.

How does the Hydrogen Peroxide gas plasma sterilization work?

right arrow

A solution of hydrogen peroxide and water (59% nominal hydrogen peroxide by weight) is delivered to the sterilizer. Then, the hydrogen peroxide is further concentrated.

The hydrogen peroxide solution is afterwards vaporized into a gas and transferred to the chamber, where it surrounds the devices and creates a biocidal environment that inactivates microorganisms with chemical interactions, applying a strong electrical field then creates hydrogen peroxide gas plasma.

The plasma is a “cloud” of highly energized species.

Once the electrical field is turned off the energized species recombine, turning the hydrogen peroxide into water and oxygen.2

In comparison to EtO and FO, H2O2 is a non-carcinogenic, non-mutagenic sterilant, which is broken down into non-toxic by-products (water and oxygen) when used as a gas plasma.

Patients and staff are therefore protected from being exposed to unnecessary health risks3.
