The Use of Liquid Nitrogen in Denver Laboratory Research


Rocky Mountain Air Solutions has been providing PurityPlus® liquid nitrogen for Denver-area laboratory use from our startup days. What makes this commodity so advantagous in all kinds of laboratory activities – particularly as a refrigerant – is its capacity to sustain temperatures markedly lower than the freezing point of water.

We’ve already discussed the use of nitrogen in food processing. In its compact, easily movable liquid form (which which doesn’t require pressurizing), we deliver it for laboratory applications as varied as …

  • cryogenics – involving the realization and analysis of low temperature extremes and the behavior of materials at such temperatures;
  • cryonics – the safeguarding of biological tissue (blood, reproductive cells, surgical samples, even human bodies) at especially low temperatures in order to resuscitate them and reanimate them sometime later; also as a way to cryoconserve genetic materials;
  • energy storage (being a mechanism for it);
  • assuring that all kinds of scientific detection instruments function more efficiently; and
  • creating lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is principally used by the laboratories that count on us …

  • to accomplish superconductivity in high-temperature superconductors;
  • to conserve the liquid helium cooling systems of high-field superconducting magnets, for instance those used in nuclear magnetic resonance spectrometers and magnetic resonance imaging systems, at an extremely low temperature;
  • in cooling baths and other testing situations meant to precipitate extremely low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras that make use of CCD image sensors.

These examples, as all-inclusive as they are, hardly account for liquid nitrogen’s use in the laboratory. Our Denver customers quite often have their own, distinctive uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also deliver.

The truth is, more and more scientific, medical, and industrial research facilities hereabouts are calling on us for the PurityPlus® nitrogen and liquid nitrogen needed to realize their research goals. They’ve found us to be a steady, ready source of these commodities. And they’ve come to depend not only on our having them when they need them, but also on their certifiable quality, our reasonable prices, and the stellar, personalized service of our people.
