Spearlab Tall Dewar

The tall dewar, can be used as a replacement for upright glass or stainless steel Dewars. This vessel is ideal for short term storage of canes for cryoEM or protein crystallography pucks. Like the standard cryogenic foam dewar, the tall dewar offers durability, safety, and convenience for processing samples, especially when transferring from conventional shipping Dewars. This vessel has a 3.5-inch cylindrical cavity, 12.3 inches deep , which gives it a capacity of 1800 ml liquid nitrogen. The outer profile is a tapered octagon, as shown in the photo.


Spearlab foam dewars are effective and durable vessels for handling liquid nitrogen and cryogenic materials. They have gained acceptance as the preferred containers for x-ray crystallography samples, and also are used in a wide variety of other cryogenic applications. Unlike conventional glass and stainless steel Dewar flasks which depend upon a vacuum layer for insulation, 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.
