High purity co2 description
Carbon dioxide (chemical formula CO2) is a colorless gas with a density about 60% higher than that of air (1.225 g/L) that is odorless at normally encountered concentrations. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally ingroundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas.

Hazards & Transportation
Carbon dioxide (Refrigerated)
H281:Contains refrigerated gas; may cause cryogenic burns or injury. May displace oxygen and cause rapid suffocation. May increase respiration and heartrate.
Contains gas under pressure; may explode if heated.
Can cause rapid suffocation. Compressed liquefied gas. Direct contact with liquid can cause frostbite.
≤ - 36.0°C
