Dewar vessels are specialized types of vacuum flasks designed for the transportation and storage of liquid nitrogen, argon, and oxygen. Dewars are also known as 'cryogenic Dewar flasks' or 'liquid nitrogen flasks.' Their construction and thermal insulation ensure the temperature inside is low enough to prevent excessive loss of cryogenic liquids, including liquid nitrogen.
Liquid nitrogen Dewars offer highly efficient storage of cryogenic liquids combined with low weight and modest space requirements. They would be suitable for use in spa and beauty centers, healthcare facilities, and research labs.
Cryomed offers liquid nitrogen Dewar flasks with a 10-, 35- and 50-liter capacity.
