It is delivered to our customers by cryogenic tankers, into onsite storage, for use in high-volume customer applications. It is stored as a cryogenic liquid in a vacuum-insulated vessel which can provide several days' supply and be used on demand as either a liquid or gas. In its liquid form nitrogen is used as a cryogen for many applications where very low temperatures or rapid temperature reduction is required.

The inert property of gaseous nitrogen enables it to be used for applications where a substance needs to be protected from oxidation or combustion by atmospheric air, or from contamination by moisture.

Application and use In its liquid form nitrogen is used as a cryogen for many applications where very low temperatures or rapid temperature reduction is required. Some common applications where nitrogen is used are: Artificial Insemination Nitrogen is often used for the storage of semen samples for artificial insemination of cattle.

Blanketing and inerting Nitrogen is used to maintain a dry inert atmosphere over chemicals during storage, reaction or processing. Food packaging Used in modified atmosphere packaging, liquid nitrogen can increase the shelf-life without the need for vacuum-packing, artificial preservatives or freezing Freeze-drying In the freeze-drying process, materials dissolved in water or organic solvents are frozen into particles or droplets.

A vacuum is applied to the freezing chamber along with a controlled amount of heat sufficient to drive off moisture by sublimation Glass Nitrogen and hydrogen are used in the float glass process for manufacturing flat glass.

In this process perfectly flat glass with a very high quality is achieved by floating liquid glass on a bath of molten tin Heat treatment Pure nitrogen is used to protect some of the most reactive metals during heat treatment. These metals readily form a protective oxide surface layer from the small amount of oxygen in the nitrogen and need no further protection Lasers Nitrogen is used as an assist gas for laser cutting of stainless steel, aluminium and non-metallic materials Metals Nitrogen is used in iron and steelworks applications for degassing and metal-stirring, purging, cooling, slag splashing, gas knives and as a carrier gas for injecting de-sulphurising compounds.

It is also used for aluminium-extrusion inerting Pipe-freezing Repairs can be made to a pipe containing a liquid by using liquid nitrogen to freeze a plug of liquid on each side of the section of pipe to be opened Purging Applications include inerting reactors and storage tanks, purging vessels and pipelines of flammable or toxic gases and vapours, and the sparging and pressure transfer of liquids Shrink-fitting Liquid nitrogen is used to shrink components so they are small enough to be inserted into another component Sample storage Liquid Nitrogen can be used to store medical or research samples such as blood, plasma and semen — safely.

Nitrogen is often used for the storage of semen samples for artificial insemination of cattle.

Nitrogen is used to maintain a dry inert atmosphere over chemicals during storage, reaction or processing. The atmosphere and ambient temperature surrounding naturally respiring products such as fruit is actively controlled to provide optimum conditions for long-term storage. Used in the inerting of printed circuit board reflow and wave ovens, to prevent oxidation and facilitate the use of weaker fluxes which decompose more easily without leaving a residue.
