The Use of Liquid Nitrogen in Cincinnati Laboratory Research


Wright Brothers has been providing PurityPlus® liquid nitrogen for Cincinnati-area laboratory use from our earliest days. What makes this commodity so beneficial in all kinds of laboratory activities – particularly as a refrigerant – is its ability to sustain temperatures markedly lower than the freezing point of water.

We’ve already described the use of nitrogen in food processing. In its dense, easily transportable liquid form (which doesn’t need pressurization), we deliver it for such laboratory uses as …

  • cryogenics – includeing the creation 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 remarkably low temperatures in order to ”reawaken” them and reanimate them at some future date; also as a way to cryoconserve genetic resources;
  • energy storage (acting as a medium for it);
  • assuring that all types of scientific detection instruments function with greater efficiency; and
  • effecting lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is most frequently applied by the laboratories we serve …

  • to effect superconductivity in high-temperature superconductors;
  • to sustain 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 especially low temperature;
  • in cooling baths and other testing situations designed to produce extremely low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras using CCD image sensors.

These examples, as comprehensive as they are, hardly account for liquid nitrogen’s use in the laboratory. Our Cincinnati customers quite often find their own, singular uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also provide.

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 require in order to accomplish their research goals. They’ve found us to be a constant, 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 competitive prices, and the stellar, personalized service of our people.
