Unlike conventional glass and stainless steel Dewar flasks which depend upon a vacuum layer for insulation, closed cell 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. Unique design makes the foam dewar easier to handle and safer to use than a traditional glass Dewar. The lower thermal mass of the foam dewar will cause less liquid nitrogen boil off when it is filled. It also will accumulate less frost during regular use. The end result is that less liquid nitrogen is consumed.
