Liquid Nitrogen, Brand Name : Cryogenics for Laboratory

Liquid nitrogen (LN2) is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air. It is a colorless, mobile liquid whose viscosity is about one-tenth that of acetone (i.e. roughly one- thirtieth that of water at room temperature). liquid nitrogen is widely used as a coolant.
