Autoclave Tape

Ever wonder if your spawn bags or jars are really sterile? Don’t second guess if your substrate has been properly sterilized by using our Autoclavable Sterilized Indicator Tape. Simply put a three or four-inch piece of this autoclave tape on each one of your jars or spawn bags. Once you’ve, “cooked” your substrate, if the proper amount of heat and/or pressure has been reached to sterilize, you will see dark lines appear on the white indicator tape, reassuring you that your pressure cooker or steam sterilizer has worked properly.

Commercial grows use this tape daily to help verify sterility.

• The tape is designed for use in a steam autoclave or pressure cooker (dry heat such as inside an over is not acceptable.)
• Dark lines will appear on the white tape after 15 minutes at 121C (250F)
• Will stick to glass, cloth, plastic, and metal without leaving a residue
• Temperature range – 7 to 121C (20 to 250F); Apply at 4 to 49C
• Each roll is 500 inches in length.
