Chemical/physical sterilization process indicator

Chemical/physical sterilization process indicators are single-use devices placed inside sterilization chambers to confirm whether the sterilization cycle has been completed successfully. They visually or physically change—such as through color shift or material transformation—to indicate exposure to the required conditions (e.g., heat, steam, or ethylene oxide), ensuring sterile medical instruments or supplies are safe for use.

These indicators are regulated as medical devices and are typically classified based on their role in ensuring sterilization integrity. They are often supplied as part of a sterilization validation system and must comply with relevant safety and performance standards to guarantee accurate process verification. Availability may vary by region, and their use is mandatory in many healthcare settings to prevent contamination risks.
