Tough-Tags are chemically resistant, flexible, polyester labels that can withstand autoclaving, boiling water baths, freezing to -40°C, or heating up to 121°C without peeling, cracking, or falling off. They adhere strongly to plastics and other materials.

Tough-Tags will accept any marking instrument. Lab markers dry instantly and stay on permanently. Tough-Tags are thin and will not stop tubes from fitting into centrifuge rotors. 1000 labels/roll.
