Steam Adhesive tape used in autoclaving (heating under high pressure with steam to sterilise) to indicate whether a specific temperature has been reached.
Small strips of the indicator tape are applied to the items before they are placed into the autoclave.
The autoclave tape is similar to masking tape but slightly more adhesive, to allow it to adhere under the hot, moist conditions of the autoclave.
Diagonal markings contain an ink which changes colour (usually beige to black) upon heating.
