Nitrogen helps create a safe environment in laboratories. As an inert gas, it will not interact with chemicals or substances in the room. Laboratories add nitrogen to the atmosphere to remove oxygen in the air and eliminate the risk of combustion that oxygen poses. Additionally, nitrogen helps regulate the lab’s temperature and humidity to maintain the integrity of sensitive equipment.
Another application of nitrogen in labs is cryogenic freezing. Tissues and other samples must be kept frozen to maintain their quality for analysis. Nitrogen for cryogenic storage may also be used for cold transport applications when samples must move from one facility to another.
