These patented Cryogenic labels (Cryo-Babies are the small sizes and Cryo-Tags are the larger), are flexible polyolefin labels that withstand conventional and cryogenic storage conditions (vapor and liquid phase nitrogen storage at -196 °C). The labels are chemically inert with a solvent resistant acrylic adhesive that will adhere to all plastics, glass and metal. Cryo-Babies and Cryo-Tags will withstand boiling water baths at 100°C and dry heat up to 150 °C without cracking, peeling or degrading.
