These silvered and evacuated Dewars feature a rugged outer casing made of galvanized steel plate with a baked enamel finish. An insulated synthetic lid seals the vessel and locks for transport with two spring clips. A detachable bail-type aluminium handle makes transportation easy. The Dewar flask is made of borosilicate glass 3.3 ISO 3585. Ideal for cooling small samples.

Note: For dry ice and liquid nitrogen storage, drill a 2-mm hole in the lid.
