In its liquid form nitrogen is used as a cryogen for many applications where very low temperatures or rapid temperature reduction is required. Liquid nitrogen is produced in large quantities at air separation plants which liquefy and distil air into its constituent parts: nitrogen, oxygen and argon. Most people use a local distributor for one of the large bull semen companies, like ABS or SelectSires, who runs a route and comes by your place and refills your tank on a regular basis. It is delivered to our customers by cryogenic tankers, into onsite storage, for use in high-volume customer applications. In the United States, Air Products or Praxair are manufacturers and distributors. Nitrogen is often used for the storage of semen samples for artificial insemination of cattle. These metals readily form a protective oxide surface layer from the small amount of oxygen in the nitrogen and need no further protection, Nitrogen is used as an assist gas for laser cutting of stainless steel, aluminium and non-metallic materials, 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. You may unsubscribe at any time. At room temperature, nitrogen it is just an average looking clear gas. Click here for more information about Medical Liquid Nitrogen, We offer e-learning courses on using liquid nitrogen safely. You can also buy it from one of the national gas distributors like Airgas or Praxair but you will probably have to pick it up at their plant and the minimum amount could be more than you need. Where to Buy Liquid Nitrogen. For example, most people have … How Cold is Liquid Nitrogen? Liquid nitrogen is transported in pressurized tanks called Dewars. OK, so you now have a liquid nitrogen tank. Since I have dealt with Liquid nitrogen on many occasions, I feel that a warning is necessary! Liquid nitrogen is a form of liquefied atmospheric gas that is used in cryogenics, the freezing of foods for transport, and in medicine and scientific research. The internet is abuzz with videos showing all of the fun things you can do with liquid nitrogen, but where do you even get the stuff? 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, Liquid nitrogen freezes food quickly, producing a higher-quality product compared to to conventional refrigeration. Nitrogen is the most prevalent chemical element in the Earth’s atmosphere and is integral to both plant growth and reproduction. By subscribing, you agree to our Terms of Use and Privacy Policy. It is also used for aluminium-extrusion inerting, 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, 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, Liquid nitrogen is used to shrink components so they are small enough to be inserted into another component, Liquid Nitrogen can be used to store medical or research samples such as blood, plasma and semen – safely, Official BOC UK Online | Industrial Gases | Products & Solutions. Where do you get the LN2 to fill it with? A vacuum is applied to the freezing chamber along with a controlled amount of heat sufficient to drive off moisture by sublimation, Nitrogen and hydrogen are used in the float glass process for manufacturing flat glass. You can contact either company to find their local distributor. Where do you get the LN2 to fill it with? Liquid nitrogen is a form of liquefied atmospheric gas that is used in cryogenics, the freezing of foods for transport, and by auto racers to burn more fuel and air in their cars' internal combustion engines.
