Nitrogen Gas

A colorless, odorless, chemically inert gas

Nitrogen constitutes 78% of the atmosphere and is a constituent of all living tissue. Under normal conditions, Nitrogen is a colorless, odorless, and tasteless inert gas which has no toxic properties and is slightly lighter than air. As a liquid at -302°F, it has a water-white appearance and must be handled with care due to its low temperature. Middlesex Gases supplies Liquid Nitrogen to commercial customers in Massachusetts, New Hampshire, Rhode Island, Connecticut and throughout New England.
