The Use of Liquid Nitrogen in Sioux Falls Laboratory Research


A-OX Welding Supply has been providing PurityPlus® liquid nitrogen for Sioux Falls-area laboratory use from the start. What makes this commodity so advantagous in such a diverse array of laboratory applications – certainly as a refrigerant – is its capacity to maintain temperatures conspicuously lower than the freezing point of water.

We’ve already described the use of nitrogen in food processing. In its condensed, readily movable liquid form (which doesn’t need pressurization), we supply it for laboratory applications as diversified as …

  • cryogenics – involving the realization and examination of low temperature extremes and how materials react at such temperatures;
  • cryonics – the safeguarding of biological tissue (blood, reproductive cells, surgical samples, even human bodies) at extremely low temperatures in order to revive them and reanimate them sometime hence; also as a way to cryoconserve genetic assets;
  • energy storage (acting as a “vehicle” for it);
  • ensuring that various scientific detection instruments perform more effectively; and
  • achieving lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is commonly used by the laboratories we serve …

  • to achieve superconductivity in high-temperature superconductors;
  • to maintain the liquid helium cooling systems of high-field superconducting magnets, including those used in nuclear magnetic resonance spectrometers and magnetic resonance imaging systems, at an exceedingly low temperature;
  • in cooling baths and other testing situations designed to generate especially low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras utilizing CCD image sensors.

These examples, as far-ranging as they are, hardly account for liquid nitrogen’s use in the laboratory. Our Sioux Falls customers commonly discover their own, distinctive uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also supply.

The upshot of it is, more and more scientific, medical, and industrial research facilities hereabouts are turn|look|com]104]ing to us for the PurityPlus® nitrogen and liquid nitrogen they must have to accomplish their research goals. They’ve found us to be a steady, easily accessible source of these commodities. And they’ve come to count not only on our providing them when they need them, but also on their certifiable quality, our reasonable prices, and the savvy, personalized service of our team.
