Vaporized hydrogen peroxide (VHP®) is a vacuum sterilization process that operates under low-temperature conditions and has traditionally been used for small objects such as reusable medical instruments, pharmaceutical containers, pre-filled syringes, electronic medical devices, and moisture or temperature-sensitive materials. But in an ever-growing market, VHP® sterilization applications can range from:
- Single-chamber units for small objects
- Pass-through chambers for transferring objects between areas in the pharmaceutical industry
- Mobile cart units for decontaminating small to medium-sized spaces or rooms up to complete facilities
- Complete integrated systems for bio-decontamination of large spaces, or complete facilities.
The fast-paced progression of VHP® is due to its ability to break down hydrogen peroxide (H2O2) into environmentally safe by-products (water H2O, oxygen O2), and the potential health hazards associated with the alternative method of Ethylene Oxide (ETO) gas sterilization.
The VHP® process has three phases: conditioning, sterilization, and aeration/post-conditioning. These phases occur in a single chamber under deep vacuum conditions usually in the range of 1-10 millibar (0.03-0.3 inches Hg), with a typical temperature range of 28-40°C (82-104°F). The total cycle time varies depending on several factors including cycle temperature, the type of object (component, assembly, material, etc.), and the weight of the load.
Finding critical components with exceptional accuracy and repeatability for monitoring and controlling the process variables through all phases that occur in VHP® Sterilizers.
Precise, consistent control and monitoring of variables such as temperature, vacuum pressure, RH, and H2O2 (Hydrogen Peroxide) vapor delivery is required for an effective vaporized hydrogen peroxide sterilization process. A simplified graphic example is shown below.
