Glove Boxes

 Glove Box Manufacturing Applications:

  • Preserve oxygen sensitive materials
  • Monitor the percent oxygen in chambers and/or glove boxes that contain oxygen sensitive components

Gases of Concern:  Argon, Helium, N2, H2

Range of Measurement:  Percent

Oxygen Monitors Used To Ensure The Suitability Of Glove Box Atmospheres

Oxygen monitors and analyzers are often used as a diagnostic tool to ensure the quality of the inert atmosphere within a glove box. Unlike a storage compartment within a car’s dashboard, however, there is another type of glove box used by industry, government institutions, and university laboratories. This “other” type of glove box (A.K.A. dry box) is a sealed enclosure designed to isolate reactive and/or hazardous materials.

Glove boxes are typically fabricated from plexiglas, stainless steel, acrylic plastics, or a combination of the above and have (a) transparent side(s). The enclosures are equipped with gloves fabricated from rubber, Hypalon, or other chemical resistant materials that provide users the ability to manipulate materials within the glove box without risking contamination of the materials and concomitantly protect the user. Glove boxes can be configured as free standing devices or for bench-top use.

When an inert atmosphere is required, the enclosures are normally purged with high purity nitrogen or argon. This inert atmosphere is maintained at a slightly positive pressure to help prevent leakage of air (oxygen contamination) into the glove box. Breathing air contains 209,000 PPM of oxygen. If the leak integrity of a glove box is less than adequate and/or the purge rate of the inert gas is unsatisfactory, oxygen leakage from room air is likely to take place. An infinitesimally small leak of air into a glove box can produce deleterious effects.

Glove Box Oxygen Analyzers

Alpha Omega Instruments manufactures glove box oxygen analyzers and monitors with the assurance that inert atmospheres are devoid of air leaks. The Company’s oxygen monitors and oxygen analyzers can be used to continuously measure oxygen concentrations within glove box atmospheres and can be used to alert users if an air leak were to take place. They include the:

  • OXY-SEN Oxygen Monitor
  • Series 3000 Trace Oxygen Analyzer
  • Series 3520 Portable Trace Oxygen Analyzer
  • Zirconia Oxide Oxygen Analyzer (ZRO 2000)

The OXY-SEN Oxygen Monitor is designed for applications where percent levels of oxygen within the glove box are to be measured.

The Series 3000 Trace Oxygen Analyzer is ideal for atmospheres that must be purged to maintain parts per million (PPM) concentrations of oxygen. The ultra-low range Series 3000 Trace Oxygen Analyzer has the ability to measure oxygen in the parts per billion range.

The Series 3520 Portable Percent Oxygen Analyzer is ideal for circumstances that require accurate and repeatable spot (trace) measurements in a variety of gases.

The Zirconia Oxide Oxygen Analyzer provides high precision oxygen measurements — in parts per billion and percent levels — in a variety of gases.
