Thorough testing of labels in end-use conditions is strongly recommended.
NitroTAG® – Cryo Barcode Labels for Liquid Nitrogen Storage
- Resistant to long-term cryogenic storage in freezers and liquid nitrogen (-196°C/-321°F)
- Perfect for cryovials, tubes, cryo-boxes, freezer-boxes, and many other cryo-containers
- Resistant to spraying and swabbing with alcohol and surface sanitizing wipes
- Require no cure time before liquid nitrogen immersion. Will also adhere to wet surfaces.
- Ideal for serialized data and barcodes, thanks to high-quality thermal-transfer printing
- Available in a large range of sizes, colors, and configurations.
NitroTAG® labels are available in a range of sizes and configurations, perfect for identifying small-diameter cryo vials, microtubes and tube tops, cardboard or polypropylene cryo/freezer boxes, cell culture plates, and plastic bags.
These thermal-transfer cryogenic labels have a strong permanent adhesive that will remain firmly and permanently attached in ultra-low temperatures. They are designed for long-term cryo-preservation under cryogenic laboratory conditions, including in liquid and vapor phase liquid nitrogen (-196°C/-321°F), freezers (-80°C/-112°F), and dry ice transportation.
NitroTAG labels require zero cure time and can be immersed in liquid nitrogen immediately after application without the need for additional tape or lamination. Additionally, these labels are waterproof, weatherproof, and durable. NitroTAG labels will adhere to wet surfaces, resist multiple freeze-thaw cycles, and can withstand elevated temperatures up to +110°C.
They are also resistant to spraying with ethanol, isopropanol, and other alcohols, bleach, and detergents (testing recommended), as well as routine wiping and rubbing with surface sanitizing wipes such as Sani- Wipe™, Eco-Wipe™, and Eco-Wipe™ Duo.
NitroTAG labels can be printed with all major brands of thermal-transfer printers. They are available in a range of colors and sizes and can be printed with alphanumeric text, as well as 1D and 2D barcodes.

Frequently Asked Questions
Yes, NitroTAG® labels are thermal-transfer printable and require a ribbon to be printed. To achieve the proper printout, NitroTAG labels require a RR-class ribbon of the same width or larger.
No, NitroTAG labels are best applied at room temperature. For labeling already frozen vials and tubes, we recommend CryoSTUCK® labels, a line of cryogenic labels especially designed for that purpose.
Please consult our handy sizing guide where you will find recommendations for the most common vial/tube sizes.
Barcoding or label design software can be used to create templates that conform to the size of your label. You can then insert design elements within the template, for easy printing.
Yes, we can provide our NitroTAG cryo labels preprinted with full-color graphics and logos, as well as variable or serialized information from a database. Learn more about our custom printing options.
No, NitroTAG labels are coated with a permanent adhesive, that is not made for easy removal. For removable cryogenic solutions see here.
