Nalgene 4150 High Density Polyethylene (HDPE) Dewar Flasks with Lid and Handle are for storing samples in liquid nitrogen, dry ice-solvent mixtures or ice water. High density polyethylene base and HDPE cover with polyethylene coated handle for strong, shatterproof performance. Double-walled sides and CFC-free foam urethane insulation minimize heat leakage so samples stay cold longer. Pour spout and bottom grip area for ease of removal of used liquids. Vented, insulated cover allows for vapor escape but maintains sample temperature. Can be used from -196°C to +100°C.
