👉 Nitrogen fluid, or liquid nitrogen, is a colorless, odorless, and highly volatile cryogenic substance with the chemical formula N₂. It exists at extremely low temperatures, typically below -196°C (-320°F), making it a unique and valuable resource. When liquid nitrogen is stored under pressure, it liquefies, forming a fluid that can be easily manipulated and transported. This fluid is widely used in various fields due to its properties: it's non-toxic, non-flammable, and readily available in large quantities. In cryopreservation, it's used to rapidly freeze biological samples like cells and tissues, preserving their viability. In industry, it's employed for cooling superconducting magnets in MRI machines and in cryogenic cooling systems for electronics. Its ability to rapidly cool and its safety profile make nitrogen fluid an indispensable resource in modern technology and medicine.
