- Liquid nitrogen is inert, colourless, odourless, non-corrosive, non-flammable, and extremely cold. It is stored and transported in steel Dewar vacuum flasks.

- PrincetonCryo.com offers the finest products, service, and customer support for liquid nitrogen storage systems.

- Liquid Nitrogen is used in high temperature thermometers where mercury cannot be used.

- Liquid Nitrogen Used in making ammonia (NH3) & light bulbs

- Used in missile work as a purge for components, insulators for space chambers.

- Use is explosives. Nitrogen can be used to make four different explosives. One of these is Ammonium Nitrate (N2 H4 O3). *In 1947, a shipload of Ammonium Nitrate went off in the harbour of Texas City, TX. The explosion wrecked the city so badly; it seemed that airplanes had bombed the city.

- The other three explosives made from Nitrogen are Nitroglycerin, Nitrocellulose, and Trinitrotoluene. You probably know Trinitrotoluene better by the initials TNT.

- Surprisingly, Nitrogen is used to make Laughing Gas as well.

- Used by the electronics industry as a blanketing medium when producing transistors, diodes, etc.

- Used in annealing stainless steel and other steel mill products.

- Used in drugs in large quantities.

- The oil industry uses nitrogen to increase the pressure in wells to force crude oil upward.

- Used as a refrigerant both for the immersion freezing of food products and for transportation of foods

- Liquid nitrogen is used in oil fields, to extinguish oil fires.

- Nitrogen is essential for synthesis of proteins in plants. Proteins are essential for synthesis of protoplasm, without which life would not exist

- Used by the chemical, petroleum, and paint industries to provide inactive atmosphere to prevent fires or explosions.

- Nitrogen in the air helps as a diluting agent and makes combustion and respiration less rapid.

- Used in metal working operations to control furnace atmosphere and in metallurgy to prevent oxidation of red-hot metals.

- Used to produce a blanketing atmosphere during processing of food stuff, to avoid oxidation of the food.

- It is also used when food is being canned, so that microorganisms do not grow.

- Nitrous gases are used as an inductive anaesthetic in pregnancy and pain relief such as in burn victims.

- Nitrogen is also an active component in the cyanide compound.

- Used as rocket fuel & propellants

- Used in making fertilizers.

- In ordinary incandescent light bulbs as an inexpensive alternative to argon.

- On top of liquid explosives as a safety measure

- Dried and pressurized, as a dielectric gas for high voltage equipment

- Filling automotive and aircraft tires due to its inertness and lack of moisture or oxidative qualities

- Use in military aircraft fuel systems to reduce fire hazard,

- Used during sample preparation procedures for chemical analysis.

- Nitrogen tanks are also replacing carbon dioxide as the main power source for paintball guns.

- Liquid nitrogen is used in the cryopreservation of blood, reproductive cells (sperm and egg), and other biological samples and materials.

- It is used in cold traps for certain laboratory equipment and to cool x-ray detectors.

- It has also been used to cool central processing units and other devices in computers which are over clocked and produce more heat than during normal operation.

- Liquid nitrogen is used to freeze and destroy skin growths, such as warts, keratoses and pre cancers.

- Liquid nitrogen can be used to cool concrete, which leads to better cured properties.

- Cold nitrogen gas is also used to cool reactors filled with catalyst during maintenance work. The cooling time can be reduced substantially.

- Used as a process gas, together with other gases for reduction of carbonization and nitriding.

- Used to treat the melt in the manufacture of metals.

- Used to maintain a neutral atmosphere in furnaces. Liquid nitrogen does not require pressure vessel storage.

- Some surgeries use a probe chilled with liquid nitrogen to kill small portions of malignant tissue, such as a brain tumour.

- Used to cool off magnets in manufacture of medical isotopes.

- Used in making yummy ice creams by stirring yoghurt under it.

- Used in making chalks.

- Used in high end generators.
