Before buying a Dewar bottle, many people have the question, will Dewar bottles explode when filled with liquid nitrogen? How to ensure the safety of the Dewar bottle?

Liquid nitrogen is -196 degrees Celsius liquid nitrogen, which means that above 196 degrees Celsius liquid nitrogen will continue to volatilize into nitrogen, at this time, if the temperature rises, nitrogen volatilization speed will suddenly become faster, each liter of liquid nitrogen vaporization, the temperature rises 15 degrees Celsius, the volume expansion of about 180 times. This means that the internal pressure of the Dewar bottle becomes larger, potentially leading to the explosion of the Dewar bottle.

Dewar bottles under normal conditions have a special shockproof design and can be transported and used in a filled state, in addition to static storage of liquid nitrogen. However, the Dewar bottle can cause the insulation layer or other parts to break after being subjected to violent collision and vibration, and the external environment can directly affect the gasification material and cause an explosion.

In addition to the risk of explosion of the Dewar bottle itself, if the Dewar bottle is placed in a closed space without ventilation, the continuously vaporized nitrogen will also gradually fill the entire space and reach the explosion limit may also cause an explosion.
