Pures

Afrox stocks a wide range of scientific pures, with your laboratory needs in mind. The material codes and descriptions listed will guide you to make the right choice.

Acetylene (C2H2, Ethyne)

Acetylene is used as a raw material for the production of electrically conducting plastics, such as polyacetylene.

Synthetic Air (80% N2 + 20% O2)

Synthetic Air is used as zero gas in the running and calibration of environmental monitoring and test measures.

Argon (Ar, R-740)

Argon is used as a carrier gas in sputtering, plasma etching and ion implantations, and as a blanket atmosphere in crystal growth.

Carbon Dioxide Pure

Carbon dioxide is used extensively as a neutralising agent for pH control, for example, in cement curing water treatment and in many other commercial applications.

Hydrogen (H2, R-702)

High purity hydrogen finds widespread usage in the electronics industry as a reducing agent and as a carrier gas.

Nitrogen (N2, R-728)

Nitrogen is used in large quantities in the chemical industry for blanketing, purging and pressure transfer of flammable chemicals.

Nitrous Oxide (N2O, R-744A)

Nitrous oxide is used as a general anaesthetic in both medical and dental surgeries. To be effective as an anaesthetic, nitrous oxide must be inhaled i with air or oxygen.

Oxygen (O2, R-732)

High purity oxygen is used for the formation of silicon dioxide and metal oxide, as an etchant for photoresist and in mixtures with halocarbons for etching silicon.

Propane (C3H8, R-290)

Propane is of interest as a specialty gas mainly in mixtures used to calibrate process control analysers in the petrochemical industry.
