Liquid Nitrogen

Liquid nitrogen is obtained by liquefying nitrogen, a colorless, odorless gas that becomes liquid at low temperatures. It becomes liquid at -196 degrees Celsius and is used in many specialized applications.

Physical Properties
  • Colorless and Odorless: Liquid nitrogen is a colorless and odorless liquid.

  • Liquefaction at Low Temperatures: Nitrogen, which is a gas at room temperature, becomes liquid at -196 degrees Celsius.

  • Intense Cooling Effect: Liquid nitrogen has the ability to cool surrounding objects very quickly.


  • Air Distillation: Nitrogen is liquefied by distilling air from the atmosphere. It is obtained by liquefying nitrogen, the main component of air, at -196 degrees Celsius.


Areas of Use
  • Medical Applications: Used in surgical interventions and medical freezing processes.

  • Industrial Cooling: Used in industrial processes, especially for cooling sensitive equipment.

  • Food Industry: Used for freezing and storage of food products.

  • Scientific Research: Used in experiments requiring low temperatures in laboratories.

  • Electronic Production: Used for cooling in the production of electronic components, especially in the semiconductor industry.


  • Frostbite Hazard: Low temperatures of liquid nitrogen can cause frostbite when in contact with skin. Requires careful handling, protective equipment and training.

  • Ventilation: Good ventilation is important if large quantities are used because vaporization of this gas can reduce oxygen levels.

Liquid nitrogen is a versatile refrigerant and freezing agent with a wide range of applications. However, given the low temperatures and potential hazards of this substance, special precautions must be taken for safe handling.
