High Purity Carbon dioxide (CO2) Gas
Liquefied, colourless gas. Asphyxiant in high concentrations. Gas density is heavier than air.


1. Carbon dioxide is used in many consumer products ranging from aerosol packaging to air guns that require pressurised gas because it is inexpensive and non-flammable; in the operation of pneumatic equipment and for the transfer of hazardous and flammable liquids.
2. A substantial volume of carbon dioxide is used for carbonating beverages such as beer and many soft drinks and conservation of wine, unfermented grape juice and various fruit juices.
3. Carbon dioxide is used to modify atmospheres, for example in green houses where it increases plant growth rates or combined with nitrogen to prolong quality in food packaging applications (MAP - Modified Atmosphere Packaging).
4. Carbon dioxide is used as media for supercritical fluid extraction (SFE) in sample preparation and as a carrier gas for analytical and preparative supercritical fluid chromatography (SFC).
5. Liquid carbon dioxide is becoming increasingly used as a refrigerant in mechanical refrigerating systems due to its environmental credentials. It has the ASHRAE number R-744. "Dry ice", or solid CO2 is commonly used for refrigeration.
6. Liquid/solid carbon dioxide is used for cooling gas chromatography ovens.
