Dewar flask
Dewar flask , also known as dewar tank, is a double-walled glass vessel designed to store and transport liquid nitrogen or other cryogenic liquids. It is commonly used in industries such as scientific research, medicine, and cryogenics. The Dewar flask's vacuum insulation helps to maintain the low temperature of the stored liquid for an extended period, making it ideal for preserving biological samples, conducting experiments at low temperatures, and storing liquefied gases. The material of a Dewar flask is typically glass or metal, with a vacuum-insulated design. Dewar flasks come in various sizes and capacities, ranging from small portable ones for laboratory use to larger ones for industrial applications.
