Autoclave tape

Definition

Autoclave tape is a specialized adhesive tape used to indicate whether items have been correctly sterilized in an autoclave. It changes color when exposed to specific temperatures and pressures.

5 Must Know Facts For Your Next Test

1. Autoclave tape contains chemical indicators that change color after exposure to the conditions necessary for sterilization.
2. It is typically placed on the outside of packages or containers to ensure they have undergone the autoclaving process.
3. The color change on the tape signifies that the autoclave reached the required temperature, usually around 121°C (250°F) with high pressure.
4. Autoclave tape does not confirm sterility but only indicates that the necessary conditions for sterilization were met.
5. It is commonly used in laboratories, medical facilities, and research institutions dealing with microbial control.
