Permanent direct thermal cryo labels for vials, microtubes, microplates, freezer boxes, and plastic bags. These barcode labels withstand long-term storage in cryogenic conditions.

• Temperature range: –196 to 93 ℃ (–321 to 199 ℉)
• Labels can withstand long-term storage in liquid Nitrogen (–196 ℃), laboratory freezers (–80 ℃, –20 ℃), and transportation in dry ice
• Ideal for the identification of vials, microtubes, microplates, and freezer boxes
• Printable with all major direct thermal printer brands
• No need for extra lamination

These cryogenic barcode labels are specially designed for printing with direct thermal printers. The thermoplastic waterproof labels are specifically designed to permanently adhere to vials, microcentrifuge tubes, microtubes, microplates, glass tubes, freezer boxes, plastic bags, and other specimen containers that will undergo long-term cryogenic and deep-freeze storage.

These labels have a strong affinity for glass, polypropylene, polyethylene, and other plastic surfaces. The cryogenic labels will remain adhered to tubes through multiple freeze-thaw cycles without cracking or peeling off. These direct thermal cryogenic labels are compatible with most cryogenic storage systems without any hindrance or risk of being scraped off. These labels do not require a self-laminate to work.
