ABOUT THIS PRODUCT

Nitrogen Liquid Gas is a crucial industrial gas widely used across various industries for its unique properties and applications. This high-purity gas is stored and transported in specially designed cylinders to ensure its safety and effectiveness. It is widely used for inerting, blanketing, and cooling in processes like welding, soldering, and semiconductor manufacturing. Liquid Nitrogen is also employed in cryopreservation and cryosurgery, and as a carrier gas in medical equipment.

10 KEY CHARACTERISTICS

1. Chemical Composition: Nitrogen (N2) is a diatomic molecule composed of two nitrogen atoms.
2. State at Room Temperature: Nitrogen is typically a gas at room temperature and atmospheric pressure. However, it can be liquefied at extremely low temperatures.
3. Boiling Point: Nitrogen boils at -196 degrees Celsius (-321 degrees Fahrenheit), making it one of the coldest substances on Earth.
4. Density: In its liquid form, nitrogen is much denser than in its gaseous state, which allows for efficient storage and transportation in specially designed containers.
5. Inertness: Nitrogen is non-reactive and relatively inert under normal conditions. It does not readily react with other substances, which makes it ideal for applications where a non-oxidizing environment is needed.
6. Solubility: Nitrogen is sparingly soluble in water, which means it does not readily dissolve in liquid form, making it suitable for various processes where contact with water is involved.
7. Cryogenic Applications: Due to its extremely low boiling point, nitrogen is used in cryogenic applications for freezing and preserving biological samples, as well as in cooling sensitive electronic components.
8. Pressure and Purging: Nitrogen is commonly used for pressure testing and purging applications in industries such as aerospace, where systems need to be tested for leaks and ensured to be gas-free.
9. Blanketing: It is often used for blanketing or padding purposes in tanks and containers to displace air or other gases, preventing oxidation or degradation of stored materials.
10. Food Preservation: In the food and beverage industry, nitrogen is used for packaging to create a controlled atmosphere that extends the shelf life of perishable goods by inhibiting microbial growth and oxidation.

10 COMMON USES

1. Food Packaging and Preservation: Nitrogen is used to create a controlled atmosphere in food packaging, extending the shelf life of perishable goods by inhibiting microbial growth and oxidative processes.
2. Cryopreservation: In medical and research applications, Nitrogen is used to cryogenically preserve biological samples, tissues, and cells at ultra-low temperatures for long-term storage.
3. Industrial Freezing and Cooling: Nitrogen is employed in various industries, including food processing, to rapidly freeze and cool products like meat, seafood, and electronics components without damaging their structure.
4. Blanketing and Padding: Nitrogen is used to displace air or other gases in tanks and containers to create an inert environment, preventing oxidation, degradation, and contamination of stored materials.
5. Welding and Soldering: In metalworking processes, Nitrogen is used as a shielding gas to protect the weld area from atmospheric contamination, ensuring a strong and clean weld.
6. Semiconductor Manufacturing: Nitrogen is essential in semiconductor fabrication for processes like chemical vapor deposition (CVD) and ion implantation, where a high-purity, inert atmosphere is required.
7. Tire Inflation: Nitrogen is used in the automotive industry to fill tires, reducing pressure loss and maintaining a more stable tire pressure over time compared to compressed air.
8. Chemical and Pharmaceutical Industries: Nitrogen is used for purging and inerting applications, preventing unwanted reactions or degradation of sensitive chemicals and pharmaceuticals during production and storage.
9. Laboratory Research: In scientific research, Nitrogen is used for various purposes, including gas chromatography, sample preparation, and as a carrier gas for analytical instruments.
10. Aerospace Applications: Nitrogen is employed in aircraft tires to prevent combustion in case of a tire fire, as well as for purging and pressure testing of aircraft fuel tanks and systems.
