Audited Supplier Liquid nitrogen is a colorless, odorless, and extremely cold substance. It is the liquid form of nitrogen, a naturally occurring element that makes up about 78% of the Earth's atmosphere.
At standard atmospheric pressure, liquid nitrogen boils at a temperature of -195.79 degrees Celsius (-320.42 degrees Fahrenheit). Due to its low boiling point, it can cause severe frostbite or tissue damage upon contact with living tissues.
Liquid nitrogen is commonly used in various applications, including:
Cryogenic preservation: Its extremely low temperature makes it ideal for freezing and preserving biological samples, such as sperm, eggs, embryos, and tissues. It is also used in the preservation of food products, such as ice cream and frozen foods.
Laboratory research: Liquid nitrogen is often used in scientific research, particularly in fields such as chemistry, physics, and biology. It can be used for rapid freezing of samples, creating a cold environment for certain experiments, or as a coolant for sensitive equipment.
Culinary applications: Liquid nitrogen is sometimes used in molecular gastronomy and food preparation. It can be used to quickly freeze ingredients or create unique textures and presentations in dishes like ice creams, sorbets, and cocktails.
Industrial processes: Liquid nitrogen finds applications in various industrial processes, including cooling and shrinking metal components during manufacturing, as a coolant for electronics, and as an inert atmosphere during certain chemical reactions.
It's worth noting that handling liquid nitrogen requires caution and proper safety measures due to its extremely low temperature and potential hazards. Protective gloves, goggles, and appropriate containers are necessary when working with or transporting liquid nitrogen to prevent direct contact and potential injury.
