The Use of Liquid Nitrogen in Pittsburgh Laboratory Research

 

Greco Gas has been producing PurityPlus® liquid nitrogen for Pittsburgh-area laboratory use since we first set up shop. The one essential characteristic that makes this commodity so advantagous in such a wide range of laboratory applications – certainly as a refrigerant – is its capacity to maintain temperatures conspicuously lower than the freezing point of water.

An earlier blog we’ve posted limns the use of nitrogen in food processing. In its condensed, easily conveyable liquid form (which which doesn’t require pressurizing), we deliver it for such laboratory applications as …

  • cryogenics – involving the realization 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 ”reawaken” them and reanimate them at some point in the future; also as a method of cryoconserving genetic resources;
  • energy storage (serving as a “vehicle” for it);
  • ensuring that all kinds of scientific detection instruments work more effectively; and
  • producing lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is most frequently employed by the laboratories we supply …

  • to effect superconductivity in high-temperature superconductors;
  • to conserve the liquid helium cooling systems of high-field superconducting magnets, e.g. 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 induce especially low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras having CCD image sensors.

These examples, as comprehensive as they are, scarcely account for liquid nitrogen’s use in the laboratory. Our Pittsburgh customers typically have their own, unique 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 depending on us for the PurityPlus® nitrogen and liquid nitrogen they require in order to accomplish their research goals. They’ve found us to be a steady, easily accessible source of these commodities. And they’ve come to rely not only on our providing them when they need them, but also on their demonstrable quality, our affordable prices, and the smart, personalized service of our staff.
