GA International also known as LabTAG, RF3-L2FSA-332NPC1-0.75WH, CryoSTUCK Cryogenic Thermal-Transfer RFID Labels for Frozen Tubes & Vials 2.75" x 1"Recommended Ribbons: RR-Class Smudge and Alcohol Proof Resin Ribbons.RFID CryoSTUCK labels were specifically designed to withstand short and long-term sample storage in liquid and vapor phase liquid nitrogen (-196°C/-321°F), lab freezers (-80°C/-112°F), and transportation on dry ice. They can also withstand temperatures up to +100°C (+212°F) in wet and dry environments, making them suitable for identifying tubes immersed in 37°C or 56°C water baths (can be readable up to 1.5"/38 mm immersion). These cryogenic RFID labels for frozen surfaces are intended for bio-banking, bio-repositories, research organizations, biopharmaceutical companies, hospitals, biotechnology and cancer research centers, molecular diagnostic laboratories, and any facility where frozen sample identification is needed.UHF RFID labels for frozen surfaces can be printed and encoded using dedicated RFID thermal-transfer printers. When printed with recommended smudge-proof RR-class of ribbons, the printout obtained is resistant to most common laboratory alcohols. The passive UHF RFID chip (Class 1, Gen 2) can be encoded with up to 32 hexadecimal characters of information. RFID CryoSTUCK labels are compatible with handheld, fixed, integrated, and cryogenic (Dewar neck) UHF RFID readers. Furthermore, they can be integrated with laboratory information management systems (LIMS) to improve sample identification and traceability, as well as to enhance process efficiency to comply with various regulations. RFID CryoSTUCK labels can also be hand-written with cryo-markers. On vials and tubes, it is recommended that these CryoSTUCK labels are applied with an overlap of at least 0.45" to ensure proper adherence to the frozen surface.Features:The labels can adhere quickly to already frozen vials and tubes (no thawing required)Flexible UHF antenna and adhesive for frozen containers allow excellent adhesion, especially on curved surfaces (cryo vials, microcentrifuge tubes, and conical tubes)Ideal for cryogenic storage, no lag time when scanning/reading multiple items at the same timeIdeal for safely thawing in heated water baths12" omnidirectional read rangeensures quick, easy, and accurate reading from every angle, without direct line-of-sight requiredUnit of measureRoll of 750 labels.
