PurityPlus® Oxygen 5.0: The Preferred Ultra-High-Purity, Research-Grade Oxygen in Portland


Cryo-Source is a vital player in producing PurityPlus® research-grade oxygen. It’s designated as Oxygen 5.0. With a 99.999% purity rating, it’s the finest grade of oxygen PurityPlus® manufactures. That makes it unreservedly appropriate for use in all kinds of critical Portland laboratory and industrial applications.

In laboratories, PurityPlus® Oxygen 5.0 is normally used as either a bleaching or an oxidizing agent, as a combustible for flame ionization detectors, and in analytical or developmental applications that profit considerably from oxygen of such purity.

Industrial uses for PurityPlus® Oxygen 5.0 range far and wide. This, for example, is the principal gas for laser-etching silicon substrates in the manufacture of semiconductors. It also serves quite often as an element in gas mixtures used to encourage industrial hygiene and safety.

[[Beyond that, you’ll find PurityPlus® Oxygen 5.0 used heavily in …

  • gas welding, gas cutting, and other such industry applications;
  • the steel industry – primarily to elevate combustion temperatures in blast and open-hearth furnaces;
  • oxidation processes critical to the chemical, pharmaceutical, and petroleum industries;
  • glass and ceramic manufacture;
  • pulp and paper manufacturing – mainly as a bleaching chemical in the manufacture of top-quality bleached pulp;
  • the medical and healthcare industries – where the greatest purity is critical, say, during surgery, for intensive-care treatment, and for inhalation therapy;
  • waste-water treatment plants.
