99% Pure High Purity Nitrogen Gas N2
99% pure High purity nitrogen N2
Use cylinder: 10L or 15l or 20L or 40L or 50L
Product Information:
1, nitrogen, chemical formula for N₂, colorless odorless gas. Nitrogen chemical property is very inactive, can react with hydrogen gas to produce ammonia gas under high temperature and high pressure and catalyst conditions;
2. Nitrogen can be combined with oxygen to produce nitric oxide under the condition of discharge; Even active metals such as Ca, Mg, Sr and Ba can react with them only when heated.
3、Nitrogen is the 30th most abundant element on Earth. Considering that nitrogen makes up four-fifths of the air mass, or more than 78% of the atmosphere, we can use almost unlimited quantities of it.
4、Aliases:High purity Nitrogen gas, N2 gas, Niitrogen gas, High purity N2 gas, 99% pure gas
5, storage: the use of seamless steel cylinders: such as 40 litres, 50 litres, 60 litres, 68 litres, 70 litres, 80 litres and so on.

Nitrogen is often called an inert gas and is used in certain inert atmospheres for metal processing and in light bulbs to prevent arcing, but it is not chemically inert.
It is an essential element in plant and animal life and is a component of many useful compounds.
Nitrogen combines with many metals to form hard nitrides that can be used as wear-resistant metals. A small amount of nitrogen in steel inhibits grain growth at high temperatures and also improves the strength of some steels.
It can also be used to create a hard surface on steel. Nitrogen can be used to make ammonia, nitric acid, nitrate, cyanide, etc.
In making explosives; Fill high temperature thermometer, incandescent bulb; An inert material is formed to preserve material for use in a drying box or glove bag.
Liquid nitrogen in food freezing process; Used as a coolant in the laboratory.

At room temperature and pressure, nitrogen is a colorless, odorless and tasteless inert gas. Nitrogen makes up about 78.1% of air. Liquid nitrogen is also colorless, odorless and lighter than water. It burns in the air.
use Chemical fertilizer, ammonia, nitric acid and other compounds manufacturing, inert protection medium, frozen food, low temperature grinding refrigerant, coolant, electronic industry epitaxial, diffusion, chemical vapor deposition, ion injection, plasma dry engraving, photography, etc., but also used as standard gas, rectification gas, zero gas, balance gas, etc.
Nitrogen must be stored in steel pressure cylinders and liquid nitrogen must be transported in insulated containers and tankers. Nitrogen is not corrosive. Carbon steel, stainless steel, copper, copper alloy, aluminum and other common metal materials and common plastic materials can be used at room temperature. For liquid nitrogen, nickel steel (90% nickel), stainless steel, copper, brass, and silicon bronze can be used. Teflon and PTFE can be used at low temperatures.
