NitroTAG® with SnapPEEL™ Technology – Cryo Barcode Labels for Liquid Nitrogen Storage (Patent Pending)

NitroTAG® labels with SnapPEEL™ technology represent an innovative and ergonomic advance in identifying cryo vials. The unique CirTANGO™ shape, consisting of an adjoined circle-and-rectangle, allows the cap and side of vials to be efficiently labeled seamlessly and effortlessly. Typical circle and rectangle labels require a separate, two-step action to affix the labels, with the dot labels often being difficult to peel and apply accurately. NitroTAG labels with SnapPEEL technology allow the circle to be precisely affixed on the vial cap; the rectangle portion can then be easily snapped off and applied on the side of the vial. This significantly increases labeling efficiency and reduces excessive manipulation and unnecessary contact with the adhesive.

Our NitroTAG series of 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), laboratory 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, and 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.


  • Increases the speed and efficiency of repetitive cryo vial labeling
  • Allows for bird’s-eye view of labeled vials
  • Require no cure time before liquid nitrogen immersion and adhere to wet surfaces
  • Ideal for printing high-quality serialized data and barcodes

Frequently Asked Questions

Yes, CirTANGO™ is an innovative new shape design that consists of an adjoined circle-and-rectangle. This allows the cap and side of vials to be efficiently labeled seamlessly and effortlessly.

Yes, these labels are thermal-transfer printable and require a ribbon to be printed. To achieve the proper printout, NitroTAG labels require an RR-class ribbon of the same width or larger.

Yes, the unique CirTANGO design allows the cap and vial to be labeled in one smooth, continuous motion, unlike traditional circle + rectangle labels requiring each label to be peeled and applied separately.

Peel the printed label set from the liner by holding the rectangle portion. Affix the circle over the cap, then snap it off and place the rectangle on the side of the vial.

No, NitroTAG labels are best applied at room temperature. For labeling already frozen vials and tubes, we recommend our CryoSTUCK® labels, a line of cryogenic labels specially designed for that purpose.

No, NitroTAG labels have a permanent adhesive that is not made for easy removal. For removable cryogenic solutions, see here.

Please consult our handy sizing guide, where you will find recommendations for the most common vial/tube sizes.

No, NitroTAG labels are meant to be printed using a thermal-transfer printer with a ribbon. Find our selection of thermal-transfer printers here. You can also consult our printer buying guide or contact our technical support team, who will be glad to help you find the right one.

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.

Yes, we can provide our NitroTAG cryo labels in different sizes, configurations, and colors. Moreover, we can incorporate SnapPEEL technology into different circle/rectangle sizes and combinations. Learn more about our custom options.
