Dewars and Cryogenic Vessels
Cryogenic storage vessels are solutions for the safe handling of liquid nitrogen and other liquid gases. With a high density material construction, the containers have a strong resistance to withstand even chemicals or corrosive liquids. Wide or narrow mouthed openings permit easy transference and pouring without spills. Offered in an array of sizes and handle styles, the cryogenic storage vessels transport dangerous liquids and prevent messes.
