Liquid nitrogen Dewar vessels are open-neck vacuum flasks for safe day-to-day handling and decanting of LN2 in laboratories, clinics, and field work. The wide neck makes filling and withdrawal straightforward while the vacuum jacket limits evaporation.
Selection is built around capacity, neck diameter, outer dimensions, and static holding time. Carrying handles, roller bases, withdrawal devices, and phase separators are matched to how the nitrogen is moved and dispensed.
Often searched as an LN2 dewar flask, liquid nitrogen container, or cryogenic dewar, this vessel serves laboratories, hospitals and clinics, cryopreservation, universities, and field service. Cryofortune supplies open-neck liquid nitrogen dewars worldwide in a range of capacities, with export packing and English-language support.
