Transparent, durable thermoplastic labels for a wide range of applications, from liquid nitrogen and freezer storage to autoclaving and dry-heat sterilization. Waterproof and wear-and-tear proof, these labels are ideally suited for the identification of cryo vials, tubes, freezer/cryo boxes, and other containers in laboratory freezers (-80°C/-112°F), liquid or vapor phase liquid nitrogen (-196°C/-321°F), and transportation on dry ice. In addition, these weatherproof, clear thermal-transfer labels can also withstand temperatures of up to 150°C (302°F), and are perfect for labeling glass bottles and other surfaces to be used in standard steam autoclave and dry heat sterilization protocols.
