Dewar Flasks

Our dewar flasks feature double-walled boroscilicate glass, vacuum pumped and silvered insuring efficient storage, transport and use of liquid nitrogen and dry-ice. Dewar flasks with lids have a vented lid to safely expel evaporating gas. Stainless steel dewar flasks with lids feature lid-clamps to secure the lid for safe transportation and minimizing spillage of contents.
