Liquid Nitrogen | Environmental Health and Safety | USU

Liquid nitrogen is inert, colorless, odorless, non corrosive, nonflammable, and extremely cold. Nitrogen makes up the major portion of the atmosphere (78% by volume). Nitrogen is inert and will not support combustion; however, it is not life supporting. When nitrogen is converted to liquid form it becomes a cryogenic liquid.

Liquid Nitrogen Facts, Safety and Uses

Liquid nitrogen consist of pure nitrogen molecules (N 2) in their liquid state. At normal pressure, nitrogen becomes a liquid below −195.8° C or −320.4° F and a solid at −209.86 °C or −345.75 °F. At these low temperatures, it is so cold it immediately freezes tissues. Liquid nitrogen, like solid and gaseous nitrogen, is colorless.

Liquid Nitrogen Treatment | Patient

After a liquid nitrogen treatment, the lump, wart or whatever is being treated will gradually discolour and fall off. The surrounding skin will sometimes become red and swollen and be sore for a day or so. It is similar to a mild burn. Occasionally a blister (sometimes a 'blood blister') forms. If this happens, it is best to pop it with a clean ...

Nitrogen Gas Supplier | Liquid Nitrogen | Air Products

Nitrogen is a non-flammable air gas that forms 78% of the earth's atmosphere. Valued for its inert properties in its gaseous form, nitrogen displaces air and therefore, reduces or eliminates the oxidation of materials. It is also used as an assist gas for laser cutting. Given the extremely low temperatures of its liquid state, nitrogen is an ...

Liquid Nitrogen Temperature

Liquid nitrogen is very cold! At normal atmospheric pressure, nitrogen is a liquid between 63 K and 77.2 K (-346°F and -320.44°F). Over this temperature range, liquid nitrogen looks much like boiling water. Below 63 K, it freezes into solid nitrogen. Because liquid nitrogen in a usual setting is boiling, its usual temperature is 77 K.

Liquid Nitrogen Safety

Liquid nitrogen is extremely cold (–320 °F / –196 °C) and rapidly converts into nitrogen gas at room temperature. In recent years, there have been incidents that have resulted in serious injuries and deaths associated with the use of liquid nitrogen. Anyone who handles liquid nitrogen should be aware of its unique properties and hazards.

Liquid nitrogen

Liquid nitrogen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid nitrogen has a boiling point of –320°F (–196°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial.

How Cryogenic Storage Works with Liquid and Vapor Nitrogen

Vapor freezers can store samples as low as -150℃. In vapor storage freezers, the liquid nitrogen is usually piped into the lower part of the freezer and the vapor is used to cool the upper racks. This can result in temperature gradients within the unit which has the potential to cause biosample degradation.

Liquid Nitrogen

Liquid nitrogen (LN) is an inert cryogenic fluid with a temperature of − 196 °C [− 320 °F]. LN is injected directly into the batch water storage tank, aggregate, or mixer via lances to lower the temperature of the concrete as much as practical without freezing. LN can be stored at the batch plant or on the project site and if used on the ...
