Liquid Nitrogen
Nitrogen Food Grade & Commercial Grade
Liquid Nitrogen
Liquid nitrogen is the liquid form of nitrogen gas that makes up about 78% of the Earth’s atmosphere. Nitrogen gas is typically obtained through a process called fractional distillation, in which air is cooled and compressed to separate its various components, including nitrogen, oxygen, and other gases.
When nitrogen gas is cooled to a temperature of -196 degrees Celsius (-321 degrees Fahrenheit), it condenses into a liquid state and becomes liquid nitrogen. At this temperature, liquid nitrogen is extremely cold and has a boiling point of -196 degrees Celsius, which makes it useful for a variety of industrial and scientific applications that require extremely low temperatures.
Properties:
Boiling point: The boiling point of liquid nitrogen is -195.79°C (-320.4°F), which makes it an extremely cold substance.
- Density: The density of liquid nitrogen is 0.807 g/cm3, which is less than that of water.
- Solubility: Liquid nitrogen is relatively insoluble in water and other common solvents.
- Thermal conductivity: Liquid nitrogen has a very low thermal conductivity, which makes it a good insulator.
- Expansion ratio: Liquid nitrogen expands to about 696 times its original volume when it vaporizes.
- Chemical properties: Liquid nitrogen is a relatively inert substance and is non-toxic, non flammable, and non-explosive.
Uses
Liquid nitrogen has a wide range of practical applications in various industries and
scientific fields. Some of its main uses include:
- Cryopreservation: Liquid nitrogen is commonly used for the long-term storage of biological samples, such as cells, tissues, and organs. This is done by cooling the samples to extremely low temperatures, which slows down their metabolic processes and prevents decay.
- Food and beverage industry: Liquid nitrogen is used as a cryogenic agent in the food and beverage industry to freeze and preserve food products. It is also used to create novel textures and presentations for food items, such as frozen cocktails or ice creams.
- Medical applications: Liquid nitrogen is used in dermatology to treat skin lesions and warts. It is also used in cryosurgery to destroy abnormal tissue, such as cancerous cells.
- Welding and metalworking: Liquid nitrogen is used in welding and metalworking to cool and shrink metal parts, which facilitates their assembly and reduces the risk of distortion.
- Electronics and semiconductor manufacturing: Liquid nitrogen is used to cool and stabilize electronic components during manufacturing, which improves their performance and reliability.
- Energy storage: Liquid nitrogen is used as an energy storage medium in some renewable energy systems, such as cryogenic batteries, which can store excess energy generated from renewable sources.
- Research and development: Liquid nitrogen is widely used in scientific research for a variety of purposes, including cooling samples, preserving biological materials, and studying the properties of materials at extremely low temperatures.
Handling and storage:
Ammonia must be handled with care due to its toxicity, flammability and corrosiveness.
It should be stored in a well-ventilated area, away from heat sources and flames.
Ammonia should be transported in specially designed containers, and the cylinder valves should be closed and not leaking before transporting.
It is important to follow the safety guidelines and regulations for the handling, transportation and storage of Ammonia, as well as wearing personal protective equipment like mask, goggles, gloves, and more.

Food Grade Nitrogen
Food grade nitrogen is a form of nitrogen that is used in the food industry for packaging, preservation, and other applications. It is highly pure and meets the standards set by regulatory agencies such as the FDA and USDA. Food grade nitrogen is used to preserve the freshness and quality of food products by slowing down the oxidation process and extending the shelf life of the products.
Food Grade Nitrogen
Food grade nitrogen is typically supplied in high-pressure cylinder or as liquid nitrogen, and can be used in a variety of applications including:
- Packaging and preservation of fresh and processed foods.
- Inert gas blanketing to protect sensitive products such as coffee, tea, and spices.
- Modified atmosphere packaging (MAP) to extend the shelf life of fresh produce, meats, and dairy products.
- Freezing and chilling of food products.
- Carbonation of beverages.
Kindly Note
It’s very important to note that the safety regulations and handling of Liquid Nitrogen is different, so it’s necessary to follow the safety guidelines and regulations for the handling, transportation and storage of the product.
