Dewar Flasks

When it’s necessary to transport or store dry ice or liquid nitrogen, the double-walled, vacuum-pumped Dewar flask is the one designed for this task. Through New Star Environmental, Dewar Flasks are available in varying sizes, fluid capacities, and in your choice of design elements and features. For example, the Blue Enameled Cased Dewar Flask with a handle and lid; the Stainless Steel Cased Dewar Flask with lid clips and handle; low-profile Dewar flasks, and more. These Dewar Flasks are rust- and corrosion-resistant and all feature the silvered borosilicate glass.
