The Use of Liquid Nitrogen in Columbus Laboratory Research


Delille Oxygen Company has been supplying PurityPlus® liquid nitrogen for Columbus-area laboratory use since we first began. The thing that makes this commodity so advantagous in such a variety of laboratory activities – particularly as a refrigerant – is its ability to maintain temperatures appreciably lower than the freezing point of water.

A previous blog we’ve posted outlines the use of nitrogen in food processing. In its condensed, easily transportable liquid form (which needn’t be pressurized), we supply it for laboratory applications as various and sundry as …

  • cryogenics – involving the realization and study of low temperature extremes and how materials behave at such temperatures;
  • cryonics – the long-term protection of biological tissue (blood, reproductive cells, surgical samples, even human bodies) at remarkably low temperatures in order to ”reawaken” them and reanimate them at some point in the future; also as a way to cryoconserve genetic materials;
  • energy storage (acting as a mechanism for it);
  • making all sorts of scientific detection instruments work more effectively; and
  • achieving lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is primarily applied by the laboratories that count on us …

  • to effect superconductivity in high-temperature superconductors;
  • to conserve 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 produce exceedingly low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras using CCD image sensors.

These examples, as comprehensive as they are, scarcely cover liquid nitrogen’s use in the laboratory. Our Columbus customers quite often have their own, singular uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also supply.

The truth is, more and more scientific, medical, and industrial research facilities hereabouts are relying on us for the PurityPlus® nitrogen and liquid nitrogen they must have to realize their research goals. They’ve found us to be a constant, accommodating source of these commodities. And they’ve come to rely not only on our delivering them when they need them, but also on their certifiable quality, our reasonable prices, and the stellar, personalized service of our staff.
