LabTAG offers a wide selection of permanent cryogenic labels for identifying small diameter cryo vials, microtubes, 2D-barcoded tubes, cryo/freezer boxes, metal racks, and vitrification devices. Available for printing with thermal-transfer, direct thermal, DYMO, and laser printers, these cryo labels have a strong adhesive designed for long-term storage in vapor phase and liquid phase liquid nitrogen (-196°C), and ultra-low temperature laboratory freezers (-80°C). Writable color dots and rectangles are also available for color coding and quick identification.
