liquid nitrogen dewar tank

Comparative Analysis: Dewar Flasks vs. Modern Low-Temperature Storage Tank Technology

Content

A liquid nitrogen dewar tank is a container designed for the storage and transportation of liquid nitrogen. Liquid nitrogen is the cryogenic liquid form of nitrogen gas, which is extremely cold, with a boiling point of around -196 degrees Celsius (-321 degrees Fahrenheit). These dewar tanks are crucial in various industries and scientific applications where extremely low temperatures are required.
