Tamper-evident cryogenic tape for sealing ultra-low temperature freezer and cryogenic containers such as cryo vials, cryo/freezer boxes, cryo cassettes, and tubes. The continuous tape will tear-up upon any attempt to remove it from most surfaces, indicating whether the contents have been compromised. Durable and waterproof, the tamper-evident tape is available in a range of colors for easy identification. Writable using our permanent cryogenic markers, the cryo tape is suitable for long-term storage in liquid nitrogen (-196°C), laboratory freezers (-80°C), and for transportation on dry ice.
