RFID NitroTAG labels are specifically designed for short and long-term storage under ultra-low temperatures and cryogenic environments, including liquid and vapor phase liquid nitrogen (-196°C/-321°F), lab freezers (-80°C/-112°F), and dry ice transportation. They have a strong permanent adhesive to ensure they will stay affixed on cryo tubes & vials*, cardboard and polypropylene cryo/freezer boxes, plastic bags, and triangular cassettes for straw storage. They can be scanned/read without the need for direct line-of-sight, even when in liquid nitrogen** or immersed up to 1.5"/38mm*** in a 37°C water bath. This can help eliminate unwanted freeze-thaw cycles, thus preserving the samples' integrity. They are ideal for biobanks, biorepositories, fertility clinics, and crystallography laboratories.
