Vaporized Hydrogen Peroxide is a newer form of sterilization used in medical applications. This process works at lower temperatures than steam, making it an alternative for items damaged by heat. Items must be checked for compatibility with the Vaporized Hydrogen Peroxide, as some materials, such as nylon, can become brittle and unusable after exposure. Tempilinks are most commonly used in producing Type 1 process indicators. They may also be used as elements to help other Types of chemical indicators.
