The Use of Liquid Nitrogen in St. Louis Laboratory Research


Cee Kay Supply, Inc. has been providing PurityPlus® liquid nitrogen for St. Louis-area laboratory use since we first set up shop. What makes this commodity so useful in such a wide range of laboratory activities – certainly as a refrigerant – is its capability of maintaining temperatures considerably lower than the freezing point of water.

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

  • cryogenics – involving the production and analysis of low temperature extremes and how materials react at such temperatures;
  • cryonics – the conservation of biological tissue (blood, reproductive cells, surgical samples, even human bodies) at uncommonly low temperatures in order to ”reawaken” 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);
  • making various scientific detection instruments operate more effectively; and
  • achieving lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is most notably 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, 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 intended to cause especially low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras that make use of CCD image sensors.

These examples, as all-inclusive as they are, hardly account for liquid nitrogen’s use in the laboratory. Our St. Louis customers quite often discover their own, unique uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also produce.

The truth is, a growing number of scientific, medical, and industrial research facilities in these parts are turn|look|com]104]ing to us for the PurityPlus® nitrogen and liquid nitrogen they need to accomplish their research goals. They’ve found us to be a trusty, 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 reasonable prices, and the smart, personalized service of our people.
