The Use of Liquid Nitrogen in Indianapolis Laboratory Research


American Welding & Gas, Inc. has been producing and selling PurityPlus® liquid nitrogen for Indianapolis-area laboratory use from the beginning. What makes this commodity so useful in such a variety of laboratory applications – particularly as a refrigerant – is its ability to retain temperatures considerably lower than the freezing point of water.

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

  • cryogenics – includeing the creation and study 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 tremendously low temperatures in order to revive them and reanimate them at some point in the future; also as a way to cryoconserve genetic materials;
  • energy storage (serving as a “vehicle” for it);
  • making various scientific detection instruments perform more effectively; and
  • achieving lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is primarily applied by the laboratories we provision …

  • to effect superconductivity in high-temperature superconductors;
  • to maintain the liquid helium cooling systems of high-field superconducting magnets, on the order of those used in nuclear magnetic resonance spectrometers and magnetic resonance imaging systems, at a very low temperature;
  • in cooling baths and other testing situations meant to generate especially low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras that make use of CCD image sensors.

These examples, as far-ranging as they are, hardly account for liquid nitrogen’s use in the laboratory. Our Indianapolis customers quite often have their own, unique uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also produce.

The upshot of it is, a growing number of scientific, medical, and industrial research facilities in these parts are calling on us for the PurityPlus® nitrogen and liquid nitrogen needed to achieve 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 verifiable quality, our competitive prices, and the stellar, personalized service of our team.
