Carbon Dioxide (CO2)
Carbon Dioxide Gas
A colorless, odorless, nonflammable, lightly acidic gas
Learn more about Carbon Dioxide gas, a colorless gas with a lightly pungent odor and biting taste. It will not burn, support combustion or sustain life. It is about 1.5 times heavier than air. Normally stored as a liquid, Carbon Dioxide exists only at a solid gas at room temperature. The solid CO2 now transforms (sublimes) directly to a gas without passing through the liquid phase. Middlesex Gases supplies Liquid Carbon Dioxide to commercial customers in Massachusetts, New Hampshire, Rhode Island and Connecticut and throughout New England.
