Nitrogen is a non-flammable, colorless, odorless and tasteless gas slightly lighter than air. It is non-toxic but do not support life and can act as asphyxiant. We offer liquid nitrogen and compressed nitrogen gas of purity 99.999 %. Nitrogen can be used as an agent in cooling, chilling and food freezing. It can be used to freeze and preserve blood tissues and other biological specimens. As an inert gas, nitrogen is used as a blanketing agent to separate sensitive products and processes from air, and as a purging agent in piping and equipment to prevent contamination. As a pressurizing gas, nitrogen can help propel liquids through pipelines. It is also used to shield oxygen-sensitive materials from the air. Another use of Nitrogen is to prevent oxidation in heat-treating processes and welding and metal fabrication. In addition to the above, it is also used to increase reservoir reserves and fracture hydrocarbon-bearing formation in oil production.
