Sterilization indicator tapes, also known as autoclave indicator tapes, are essential tools for monitoring the discoloration indication during sterilization processes.
1. Apply 5 to 6 cm of steam indicating chemical tape to the package or container. Ensure the cross-wound is at least two weeks for secure fixing.
2. Place in a steam pressure sterilizer at 120°C for 20 minutes, or a 134°C pre-vacuum sterilizer for 3.5 minutes.
Visual Confirmation: The indicator changes from light yellow to grayish black or black, confirming the sterilization meets requirements.
