The Foam Dewars offer improved safety, durability, economy and performance.
SpearLab Foam dewars are effective and durable vessels for handling liquid nitrogen and cryogenic materials.
The preferred containers for x-ray crystallography samples, and also are used in a wide variety of other cryogenic applications.
Spearlab foam dewars use a fine closed cell foam for insulation. This foam material is chemically inert and mechanically durable enough to be exposed directly to liquid nitrogen, without leaking or degrading.
