Cryo-Babies are ideally used for 0.5ml and 2.0ml tubes and Cryo-Tags are used for general-purpose applications. Cryo-Babies and Cryo Tags can withstand freezer temperatures down to -196°C (liquid and vapor phase nitrogen), boiling water baths (100°C), autoclaving and moderate oven temperature (150°C). They will resist water soaking for at least 24 hours at room temperature and water vapor (100% relative humidity) at 35°C for at least 24 hours. These are chemically inert labels and resist most organic solvents and caustic agents. Made with a flexible, polylefin label material and acrylic adhesive. This unique combination expands and contract together with temperature fluctuations resulting in strong adhesive bond.
