Pure Gases


From acetylene to xenon, Airgas, an Air Liquide company, provides nearly 50 different pure gases for all your laboratory needs.

Keep purity on-point

For argon, helium and nitrogen, we also offer BIP® Technology, featuring a built-in purifier. More efficient than traditional point-of-use purifiers, the BIP purification process takes place in the high-pressure, lower-velocity environment within the cylinder—more thoroughly exposing the purifier medium to any impurities.

The right supply modes

You can count on Airgas to meet your gas supply needs safely and reliably with a full range of supply modes, including:

  • High- and low-pressure cylinders
  • Portable liquid dewars
  • Airgas MicroBulk
  • On-site tube trailers
