These labels are intended for identifying already frozen vials and tubes under deep-freeze conditions (−80 °C) prior to storage in ultra-low temperature lab freezers and liquid nitrogen tanks (−196 °C).

• Temperature range: −196 to 110 °C (−321 to 230 °F)
• Labels can adhere to already frozen vials (no thawing required)
• Ideal for long-term storage in cryogenic conditions (−196 °C)
• Ideal for safely thawing in water baths
• Printable with all major thermal-transfer printer brands

An ideal solution for bio-banks and bio-repositories that need labeling or relabeling of already frozen samples (plastic and glass vials and tubes) inside liquid nitrogen tanks and freezers as this task proves challenging due to extremely low temperatures, frost, and moisture accumulated on the surface of these cryogenic containers. These cryogenic labels can be applied on −80 °C surfaces and then stored back in laboratory freezers or liquid nitrogen to preserve the integrity of the sample. Available in roll format for thermal transfer printing, which provides a smudge-proof printout even in extreme low temperatures. On vials and tubes, it is recommended that those labels are applied with an overlap of at least 0.25" to ensure proper adherence to the frozen surface.
