How the REVOX Peracetic Acid Solution Offers Medical Manufacturers an Alternative to Hydrogen Peroxide

Hydrogen peroxide (H2O2) is a powerful chemical sterilizing agent, and for more than twenty years hospitals, laboratories, and manufacturing processes have been using it in vaporized form (VHP) for decontamination. It’s a potent oxidant, which means it’s effective in killing a wide range of pathogens, spore-forming bacteria, and other microbes. It also has a shorter cycle time than Ethylene Oxide (EO), which helps it provide greater throughput for sterilizing medical instruments in a hospital setting.

However, when compared to REVOX® Sterilization’s innovative vaporized peracetic acid (VPA) process, H2O2 has some limitations due to the higher temperatures it requires, the types and quantity of materials it can sterilize, and the potential safety risks it poses. REVOX PA® provides an alternative solution that’s just as strong as H2O2, but it acts more efficiently, sterilizes heat-sensitive items, and achieves results more safely.

Lower Temperature

For many manufacturers, the biggest problem with H2O2 sterilization is that it requires the materials to be treated at high temperatures, in excess of 50˚C. While these temperatures are not as high as those used in steam-based sterilization, they can still be too hot for many applications. For example, several high-tech devices in the medical, biological, and drug-delivery fields—including electronic sensors or items with embedded batteries—are sensitive to high or low temperatures, which preclude H2O2 sterilization from being used. By contrast, the REVOX system operates consistently at room temperature (18°C–30°C), making it much more compatible for a variety of materials.

Greater Material Compatibility

While H2O2 is a notably strong chemical sterilant, it is not compatible with some types of materials due to its high (95 percent) oxidizing chemical concentration. REVOX PA® is a proprietary chemical designed to be particularly effective in its vapor form.   With greater materials compatibility, the REVOX sterilization process enables the innovation potential that new materials bring. 

Increased Productivity

The largest VHP systems have sterilization chambers that are 100 liters in total volume. By contrast, REVOX chambers range from 417 liters to 3,000 liters with potential for even larger sizes, which means they can sterilize more product simultaneously, saving time and money, and significantly increasing throughput. A typical REVOX sterilization cycle takes only two to four hours from start to finish, and cycles can be customized to meet specific in-line efficiency objectives.

REVOX Sterilization’s larger capacity chambers and lower temperature operational characteristics mean it can be safely inserted right into the production line, offering increased throughput via in-line sterilization. These characteristics provide a JUST IN TIME™ sterilization process within a JIT manufacturing facility.
