Spearlab Foam Large Vessel

A slightly bigger version of the standard vessel. Cavity 6.3 inches in diameter by 3.8 inches deep, holding 1400 ml.

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.
