GA International also known as LabTAG, UC-7C3-5WH, Thermal-Transfer Cryogenic Label for Frozen Vials & Surfaces - 1" x 0.5", CoreFeatures:Ultra-resistant adhesive ensures no flagging or detachment when stored in liquid nitrogenThermal-transfer printable for the best printout and barcode qualityIdeal for labeling ambient temperature as well as frozen surfaces without thawing firstNo overlap or wrap-around required for proper adhesionWide temperature range resistanceCircle labels are suitable for cryo vial caps, even when already frozenThese cryogenic labels provide an all-in-one solution for cryo storage as they firmly adhere to both ambient and already frozen surfaces (as low as -80°C/-112°F) without the need for thawing, cure time, or any other special treatment. They maintain excellent long-term adhesion when stored under cryogenic conditions. Due to their special adhesive and conformable design, these cryo labels can be applied onto both flat and curved surfaces, ideal for identifying cryo vials, microtubes, as well as cardboard and polycarbonate storage boxes destined for long-term storage in liquid nitrogen tanks (-196°C/-321°F), ultra-low temperature freezers (-80°C) and dry ice transportation. Perfectly suited for identifying vials destined for immediate immersion in liquid nitrogen as well as labeling already frozen vials without having to thaw them first, thus preserving the biological integrity of the frozen specimens. These permanent cryo labels will also resist elevated temperatures up to +121°C/+249°F and are perfectly suitable for identifying containers destined for heated water bath thawing directly after removal from ultra-low temperature storage. Furthermore, these durable labels resist standard steam autoclave sterilization conditions (+121°C/+249°F, 16 psi, 20 minutes).
