Permanent Cryo-LazrTAG™- Cryogenic Labels for Laser Printers (PATENTED)


  • Strong permanent adhesive ensures labels won’t wrinkle or peel
  • Resist ultra-low temperatures (-80° laboratory freezers and dry ice transportation)*
  • Available in a wide range of colors, perfect for color-coding
  • Printable by all major desktop laser printers
  • Resistant to gamma irradiation (tested to up to 50kGy)

Coated with a unique cryo adhesive, Cryo-LazrTAG™ thermoplastic waterproof labels are specifically designed to permanently adhere to the caps of 1.5 and 2ml vials and microtubes that will undergo long-term deep-freeze storage. Provided in sheet format for printing with desktop laser printers, these cryogenic tags are wear and tear proof; do not jam printers; resistant to UV and Gamma irradiation.

*Given the small diameter of these dot labels, they are not recommended for liquid nitrogen storage. For labels of the same size and suitable for storage in vapour phase and liquid phase liquid nitrogen, we recommend: NitroTAG®, and writable LAB-TAG™.

Frequently Asked Questions

No, Cryo-LazrTAG labels are designed to be printed using desktop laser printer brands, such as Brother, HP, Canon, and Samsung. Laser labels will not feed through consistently, and may damage inkjet printers.

We supply our Cryo-LazrTAG sheet labels in US letter size (8.5” x 11”), in European A4 (210 mm x x297 mm) and Hagaki (4” x 6”). For more information, please consult our expert technical support team.

See our label templates page to find your appropriate format and download the MS Word template associated with your labels.

Yes, Cryo-LazrTAG labels are designed for on-demand printing, they allow only a few labels to be printed, while saving the rest for later. These laser labels can withstand multiple passes in desktop laser printers, and will not peel-off or jam the printer.

Press the print button, then click “properties” next to your printer’s name. Ensure Media/Paper type is set to “label”. If label is not an option, select “thick paper”. For more help with printer troubleshooting see our more detailed FAQ.

No, special toner is not required for printing Cryo-LazrTAG labels. These labels can be printed using standard laser printer toner, compatible with your printer of choice.

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

No, these Cryo-LazrTAG labels are not removable. For removable cryogenic labels for laser printers, see here.

No, Cryo-LazrTAG labels are best applied at room temperature. For labeling already frozen vials and tubes using laser labels, we recommend our new laser CryoSTUCK line of cryogenic labels especially designed for labeling already frozen surfaces.

Laser labels are waterproof and resistant to long-term storage in liquid nitrogen. However, they have limited resistance to harsh chemicals, so for any cryo containers that may encounter chemicals, we recommend our thermal-transfer cryo labels.

No, these labels are designed for cryogenic use, and are not suitable for high-heat conditions. For autoclave-resistant laser labels see here.

Yes, Cryo-LazrTAG labels can be inscribed using ballpoint pens, permanent cryogenic markers. We recommend our Science-Marker, which are also alcohol and water-resistant.

For office work, and labeling file folders, we suggest our laser and inkjet printable paper labels.
