The Use of Liquid Nitrogen in Atlanta, GA Laboratory Research


Sidney Lee Medical & Scientific Gases has been producing PurityPlus® liquid nitrogen for Atlanta, GA-area laboratory use from our startup days. What makes this commodity so advantagous in such a variety of laboratory activities – certainly as a refrigerant – is its capacity to sustain temperatures conspicuously lower than the freezing point of water.

An earlier blog of ours discusses the use of nitrogen in food processing. In its compact, readily movable liquid form (which doesn’t call for pressurization), we offer it for such laboratory uses 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 exceptionally low temperatures in order to revive them and reanimate them at a later date; also as a way to cryoconserve genetic assets;
  • energy storage (serving as a mechanism for it);
  • ensuring that all types of scientific detection instruments work more efficiently and effectively; and
  • achieving lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is principally employed by the laboratories we provision …

  • to achieve superconductivity in high-temperature superconductors;
  • to maintain the liquid helium cooling systems of high-field superconducting magnets, including 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 extremely low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras using CCD image sensors.

These examples, as all-inclusive as they are, hardly cover liquid nitrogen’s use in the laboratory. Our Atlanta, GA customers quite often find their own, distinctive 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 in this area are calling on us for the PurityPlus® nitrogen and liquid nitrogen they must have to accomplish their research goals. They’ve found us to be a trusty, ready 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 competitive prices, and the expert, personalized service of our team.
