Foam Standard Vessel

Holds 800 ml of liquid nitrogen. Teardrop shape with a protruding handle and matching foam lid. Cavity 5.8 inches in diameter by 2.8 inches deep.

Spearlab foam dewars are effective, durable vessels for handling liquid nitrogen and cryogenic materials, widely used for x-ray crystallography samples and other cryogenic applications. Unlike conventional glass and stainless steel Dewar flasks that depend on a vacuum layer, Spearlab foam dewars use a fine closed-cell foam for insulation — chemically inert and mechanically durable enough to be exposed directly to liquid nitrogen without leaking or degrading.
