Cryo Labels (Extra Permanent)


Please note that our JTT-class of labels will be replaced shortly and gradually (upon remaining inventory sold) by the newly improved JTTA NitroTAG™ class.

labels are ideally suited for storage of small diameter cryotubes & cryovials, polypropylene cryo/freezer boxes, cardboard freezer boxes, cell culture plates, plastic bags as well as other containers in liquid and vapour phase liquid nitrogen (-196ºC), liquid helium (-269ºC) and laboratory freezers (-120ºC, -80ºC, -20ºC).

These cryogenic labels, made of strong thermoplastic film, can be immersed in liquid nitrogen immediately following application, without the need for any additional tape or laminate, due to their design which includes an extra-permanent cryo adhesive (CryoMax).

NitroTAG™ products have been to shown to be waterproof, able to adhere to wet and moist surfaces, as well as durable, capable of withstanding a range of extreme temperatures including multiple freeze-thaw cycles, transportation on dry-ice, and sterilization by Gamma irradiation (tested up to 50 KGy). The labels are also weather- proof and grease-proof, allowing them to be used for outdoor applications such as labelling plants, flowers, gas and oil production equipment, and much more.

These cryogenic labels are also resistant to spraying with various detergents and chemicals including ethanol, isopropanol and other alcohols (further testing recommended), bleach and DMSO. Printing of NitroTAG™ labels with our RR-class resin ribbons provides printout resistance to alcohol and mild solvents.

The labels are resistant to standard ethylene oxide gas sterilization, consisting of a 60-minute exposure to 759mg/L of ethylene oxide gas, at 55oC, and 40-80% relative humidity, followed by a two-hour aeration cycle.

NitroTAG™ cryo labels are compatible with all major brands of thermal-transfer barcode printers including Zebra, Datamax O’Neil, Sato, CAB, Intermec and more. The labels are available in roll format, on 1” and 3” cores.

FDA Compliance: FDA 21 CFR 175.105 for indirect food contact.

RoHS compliant.
