Liquid nitrogen dewar and cryogenic nitrogen dewars
Liquid nitrogen dewar also known as a cryogenic dewar or LN2 dewar, is a specialized container designed for the storage and transportation of liquid nitrogen (LN2) at extremely low temperatures. Liquid nitrogen is a cryogenic liquid with a boiling point of around -196 degrees Celsius (-321 degrees Fahrenheit) at atmospheric pressure. Due to its extremely cold temperature, it requires specialized storage solutions to prevent rapid evaporation and maintain its cryogenic properties. Here are some key points about liquid nitrogen dewars: Design and Construction: Liquid nitrogen dewars are typically constructed from materials with low thermal conductivity, such as stainless steel or glass-reinforced plastic, to minimize heat transfer from the environment. They consist of an inner vessel to hold the liquid nitrogen, an insulating vacuum layer to reduce heat transfer, and an outer protective casing.
