Professional Grade Sterility Insurance – 12.5mm x 50m –   Removable with no glue residue

Stop guessing if your pressure cooker reached the core of your spawn bags. This lead-free indicator tape provides a clear visual “pass/fail” for every sterilization run. Unlike other tapes the adhesive on the Autoclave Indicator Tape is easy to remove and leaves no residue – so locate the flaps of your bags to prevent dislodging during autoclave/movement and ensure a perfect auto-seal function of bags after autoclave.

Key Features:

• Visual Confirmation: Diagonal white stripes turn dark black/brown once the target temperature of 121 °C is maintained.

• High-Tack Adhesion: Specifically formulated to stick to Polypropylene (PP) bags even in high-pressure steam environments.

• Clean Removal: Unlike masking or electrical tape, this peels off cooled bags without leaving a gummy residue or tearing the plastic.

• Lead-Free & Non-Toxic: Safe for use in home kitchens and around food-grade gourmet mushroom cultures.
