Oxygen
USW has long been a premier supplier of pure oxygen and bulk storage equipment to medical facilities. Beyond supplying bulk oxygen, USW also:

  • Designs and installs safe, smoothly functioning bulk liquid oxygen storage systems for efficient supply.
  • Familiarizes you and your staff with sometimes confusing federal, state, and local regulatory codes governing oxygen supply installations.
  • Provides minimum 24-hour reserve supplies of bulk oxygen.
  • Installs USW’s computerized remote monitoring system.
  • Ensures that your oxygen supplies are not interrupted during supplier changeover or a new bulk storage installation.
  • For homecare assistance, USW provides three systems which deliver oxygen: concentrators, compressed gas systems, and liquid systems.

Laboratory Gases

  • Instrument gases
  • Clinical stable isotopic gases
    • Carbon monoxide-neon
    • Carbon monoxide-acetylene-helium
    • Carbon monoxide-helium-oxygen
    • Carbon monoxide-acetylene-helium-oxygen
    • Pure gases
    • Acetylene
    • Air
    • Argon
    • Carbon dioxide
    • Helium
    • Hydrogen
    • Methane
    • Nitrogen
    • Oxygen
    • Propane

Sterilant Gases
USW supplies ethylene oxide-based sterilant gases. These gases are used in the sterilization of a variety of medical devices, surgical equipment, and similar materials used in the healthcare industry. Our Specialty Gases operations utilizes special cylinder cleaning and inspection procedures to ensure the purity of these products, minimizing polymer problems.

Liquid Helium
Helium is used as a component of breathing mixtures to reduce the density of the mixture to facilitate breathing under certain physical and physiological conditions.

In Magnetic Resonance Imaging (MRI) machines, helium cools electromagnetic coils to super conductive levels. This decreases the metal’s ordinary resistance to the electrical current and results in high-resolution images.

Nitrogen
Nitrogen is used as a component in many gas mixtures and as a displacement medium for sterile equipment. It is also used as a non-oxidizing displacement medium in pharmaceutical vials and as a propellant in pressurized aerosol type dispensers. Nitrogen provides a source of pneumatic pressure to power gas-operated medical devices and as a coolant for carbon dioxide surgical lasers.

Nitrogen is also used to freeze and preserve blood, tissue, semen and other biological specimens and to freeze and destroy diseased tissue in cryosurgery and dermatology. It may also be used to pre-cool or insulate Magnetic Resonance Imaging (MRI) machines which conserves helium.

Carbon Dioxide
Carbon dioxide is used for close-to-physiologic atmospheres for the operation of artificial organs and in cryosurgery with insufflators during lapriscopic surgery. Carbon dioxide is also used as a component in a mixture of oxygen or air as a respiratory stimulant to promote deep breathing.

Nitrous Oxide
Nitrous oxide is used as an analgesic, often in combination with other agents for the production of anesthesia. Nitrous oxide is also used in cryosurgery.

Medical Air
Medical air is used in respiratory therapy and humidity treatments using nebulizers.

Pure Specialty Gases

USW supplies pure instrumentation gases to laboratories.  As analytical instrument manufacturers continue to push the thresholds of sensitivity and detection limits, so does USW in producing application specific pure gas grades that will meet these stringent specifications. Equally important, USW will help you deliver these critical purities to your instrument applications by assisting with the associated gas handling equipment for assured results.

USW also offers a wide range of pure organic products for the petrochemical industry. These raw materials often have more stringent specifications than other commercially available materials. To meet these more stringent specifications, USW utilizes proprietary purification processes.

USW provides a full line of zero and support gases developed to meet the stringent requirements of each specific environmental application. We offer Continuous Emission Monitoring (CEM) zero grade air and nitrogen; Vehicle Emission Zero (VEZ) grade air, nitrogen and Volatile Organic Compound (VOC) free grade air, helium and nitrogen.

Our highly trained team of field sales representatives, technical service personnel and production chemists provide the guidance and support you need to resolve regulatory, technical and safety issues.

Specialty Gas Mixtures

USW provides the very latest in gas mixture technology for our customers.  USW is a leading supplier of a complete line of exacting, consistent gas mixtures used in environmental, industrial, medical, and scientific applications. We supply mixtures made from 2 to in excess of 40 components and follow rigid safety and quality standards throughout the production process.

Welding & Cutting

USW offers a complete line of specialized shielding and cutting gases required for efficient and high-quality metal fabrication.

Shielding Gases
Argon and other shielding gas mixtures are used during the welding process to shield welds as they solidify, preventing oxidation. These gases significantly improve quality, reduce waste, boost productivity and decrease fumes.
