A Liquid Nitrogen Tank is a specialized container designed to store and transport liquid nitrogen at extremely low temperatures, typically around -196 degrees Celsius (-321 degrees Fahrenheit). These tanks are made from materials that can withstand such cold and are often insulated to minimize heat transfer, ensuring the nitrogen remains in its liquid state. Liquid nitrogen is commonly used in various applications, including cryopreservation of biological samples, such as cells and tissues, and in the food industry for flash freezing. The tanks come in different sizes and are equipped with safety features to prevent pressure buildup and ensure safe handling.
