Dewar bottle, using the vacuum layer of good insulation properties to preserve the temperature of the inner layer of objects. Dewar bottle is a double-layer construction, and the difference with the life of the warm water bottle is that it is more sophisticated, double-layer aviation aluminum bile between the vacuum and other aspects of the higher requirements.
The liquid nitrogen Dewar bottle is usually used to preserve the liquid nitrogen for a longer period of time, to use the low temperature of liquid nitrogen to keep the sample inside the bottle active. Because liquid nitrogen will vaporize at -196°C, even in a Dewar bottle it is constantly changing into nitrogen, so a good Dewar bottle can make the liquid nitrogen vaporize more slowly and keep it longer. Each Dewar bottle is carefully manufactured through one process in the factory, and each Dewar bottle has been tested for volatility of liquid nitrogen and is better than the volatility amount specified in the national standard.
