LabTAG AHA-501NOTC3-0.5 Clear CryoSTUCK - Cryogenic Thermal-Transfer Labels for Frozen Containers 3" x 4.75", Transparent, 3" Core

These labels are designed to adhere directly to already frozen tubes and cryo vials. These labels are perfectly suited for long-term cryo-preservation of cryo tubes and vials in liquid and vapor phase liquid nitrogen (-196°C/-321°F) and laboratory freezers (-80°C / -112°F), as well as transportation on dry ice. An overlap of at least 0.25" is recommended to ensure proper adherence to the frozen surface.
