Liquid Nitrogen

Liquid nitrogen is inert, colorless, odorless, noncorrosive, nonflammable, and extremely cold. Liquid nitrogen has a boiling point of –320°F (–196°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial. Keeping this surrounding heat from the product requires special equipment to store and handle cryogenic liquids. In its liquid state, nitrogen is used for food freezing, plastic and rubber deflashing and grinding, cooling, metal treating, biological sample preservation, pulverization, and other temperature-related applications.
