Sterilization Indicator Card

　　The product combines chemical substances with a color‑developing agent and auxiliary ingredients to form an ink, which is then printed onto a specialized cardstock. Under appropriate temperature, humidity, and pressure conditions, the indicator color block provides a quick and intuitive indication of whether the sterilized item has undergone sterilization, and the post‑sterilization color is resistant to fading.

　　It is compatible with various sterilization methods, such as steam under pressure, ethylene oxide, and low‑temperature plasma.
