The Use of Liquid Nitrogen in Pittsburgh Laboratory Research


Butler Gas Products has been providing PurityPlus® liquid nitrogen for Pittsburgh-area laboratory use since we first opened our doors. The thing that makes this commodity so advantagous in all kinds of laboratory situations – particularly as a refrigerant – is its capacity to hold temperatures conspicuously lower than the freezing point of water.

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

  • cryogenics – involving the creation and examination of low temperature extremes and how materials behave at such temperatures;
  • cryonics – the safeguarding of biological tissue (blood, reproductive cells, surgical samples, even human bodies) at remarkably low temperatures in order to resuscitate them and reanimate them at some point in the future; also as a method of cryoconserving genetic materials;
  • energy storage (being a mechanism for it);
  • assuring that all sorts of scientific detection instruments function more efficiently; and
  • generating lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is commonly employed by the laboratories that rely on us …

  • to effect superconductivity in high-temperature superconductors;
  • to conserve 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 extremely low temperature;
  • in cooling baths and other testing situations meant to induce especially low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras that make use of CCD image sensors.

These examples, as all-encompassing as they are, scarcely cover liquid nitrogen’s use in the laboratory. Our Pittsburgh customers quite often find 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, more and more scientific, medical, and industrial research facilities in this area 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, ready source of these commodities. And they’ve come to count not only on our supplying them when they need them, but also on their verifiable quality, our competitive prices, and the expert, personalized service of our team.
