What is a Dewar Vessel?

Dewar vessels are specialized types of vacuum flasks (also known as “cryogenic dewar flasks” or “liquid nitrogen flasks”) designed for transportation and storage of large quantities of liquid nitrogen, argon and oxygen. The high construction efficiency of the thermal insulation system guarantees the maximum duration of cryogen storage.

Liquid nitrogen Dewars offer highly efficient cryopreservation combined with low weight and modest space requirements. They would be suitable for use in research labs, spa and beauty centers, healthcare, industrial construction and sports medicine.

Cryomed liquid nitrogen dewar flasks are available in different sizes – small and large: 5; 10; 16; 35; 40; 45 liters volume.
