A cryogenic storage dewar (or simply dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature. It is named after inventor James Dewar, who developed it for his own work.

Cryogenic storage dewars are specialized vacuum flasks that hold liquid nitrogen or liquid helium (cryogens). Choosing the right dewar that best suits your application is critical. A liquid nitrogen dewar should have the shape, capacity, and material construction to store your sample.

The ideal cryogenic liquid nitrogen dewar for interaction with LN2 liquefiers. Equally good for liquid argon and oxygen. Easy to move and conveniently accessible in multiple sizes and configurations.

2020年9月23日 · High pressure vessels are generally referred to as tanks, whereas Low pressure containers are generally referred to as dewars. Many people use the word “dewar” to describe a “liquid cylinder”, and vice versa. There are some key …

A dewar container—sometimes called a dewar flask or dewar—is a vessel with a vacuum space between a cold liquid and the outside walls of the vessel. One common type of dewar container is a thermos that you might use to keep drinks cold.

2020年2月11日 · In a low-pressure liquid nitrogen dewar, the pressure inside the vessel is maintained through the normal heat-leak of the cylinder. As the liquid warms, it evaporates and expands to almost 700 times its liquid volume, which increases the pressure inside the vessel.

U.S. Solid provides a comprehensive range of dewars engineered for the long-term cryogenic storage of liquid nitrogen and biological samples. Utilizing advanced vacuum technology and superior insulation, our dewars offer exceptional holding times, often exceeding those of …

Our dewar containers and cryogenic tanks are designed to store, transport, and dispense cryogens with minimum loss. See our expertly engineered solutions for liquid helium, liquid nitrogen, liquid oxygen, liquid argon and liquid hydrogen.

2015年3月11日 · Cryogenic storage dewars are tailor-made for liquid nitrogen, providing optimal shape, capacity, and materials for storage. Liquid nitrogen, staying cold without pressurization, maintains temperatures well below freezing, serving various purposes in different fields.
