Cryogenic Dewar Flasks


Cryogenic aluminum dewar flasks are specifically designed to safely store cryogens for transport of samples within a facility.  Our LN2 dewar flasks feature a tough, robust and rust-free construction, suitable for liquid nitrogen or dry-ice.  To raise the boiling temperature and thus prevent evaporation, their double-thick walls are vacuum-pumped and provide a thermal insulation between the interior of the cryogenic dewar and the exterior environment.  We have a variety of economical, stainless steel and low profile units available in a wide range of sizes to meet any need.
