nalgene polyethylene dewar flaskarrow12Nalgene® Polyethylene Dewar Flask

High density polyethylene Dewar Flask with vented and insulated HDPE covers. They are unbreakable, chemically resistant, and withstand temperatures from -196 to 100°C (-321 to 212°F). Double walls are filled with foamed urethane to minimize heat exchange. May be used for short term storage of dry ice-solvent, liquid nitrogen, or for use as a hot bath. They are ideal for storing frozen biological specimens. All available sizes feature molded-in-ribs for stability and a carrying handle on the 1, 2, and 4 liter sizes.

arrow12Foam Cryo Dewars

The preferred containers for handling liquid nitrogen and cryogenic materials

These foam dewars are safe, durable, and have superior insulating properties compared to stainless or glass, at a fraction of the cost!

Foam dewars use fine closed cell foam for insulation, which is chemically inert and mechanically durable enough to be exposed directly to liquid nitrogen, without leaking or degrading.

Also, due to the lower thermal mass, foam vessels cause less liquid nitrogen boiloff when filled, and will accumulate less frost. This results in less liquid nitrogen being used.

All vessels feature a foam lid.
