Liquid nitrogen cylinder description

Nitrogen is colorless, odorless, tasteless, nontoxic, inert and represents 78.08% of the atmosphere. Nitrogen is nonflammable and does not support combustion.

It is slightly soluble in water and most other liquids. Nitrogen does not conduct heat and electricity well.

Applications

1)Carrier gas in gas chromatography.

2)Zero gas in analytical instruments.

3)Freezing and packaging of food.

4)As a reducing gas to provide and oxygen free atmosphere.

5)Liquid nitrogen can be used for freezing of liquids in pipelines for emergencies, low temperature stabilization, prevention of blood, sperm and other biological and refrigeration of food.
