The Use of Liquid Nitrogen in Laboratory Research

Arc3 Gases has been providing PurityPlus® liquid nitrogen for local-area laboratory use from the start. The thing that makes this commodity so useful in such a diverse array of laboratory activities – certainly as a refrigerant – is its ability to hold temperatures appreciably lower than the freezing point of water.

An earlier blog of ours limns the use of nitrogen in food processing. In its dense, easily conveyable liquid form (which which doesn’t require pressurizing), we supply it for laboratory applications as varied as …

  • cryogenics – includeing the production and examination of low temperature extremes and the behavior of materials at such temperatures;
  • cryonics – the long-term protection of biological tissue (blood, reproductive cells, surgical samples, even human bodies) at extraordinarily low temperatures in order to revive them and reanimate them at a later date; also as a means of cryoconserving genetic resources;
  • energy storage (serving as a “vehicle” for it);
  • insuring 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 primarily used by the laboratories we serve …

  • to effect superconductivity in high-temperature superconductors;
  • to sustain the liquid helium cooling systems of high-field superconducting magnets, on the order of 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 cause very low-temperature chemical reactions;
  • in vacuum-pump traps; and
  • in astronomy cameras utilizing CCD image sensors.

These examples, as far-ranging as they are, hardly account for liquid nitrogen’s use in the laboratory. Our customers typically have their own, singular uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also supply.

The truth is, an increasing number of scientific, medical, and industrial research facilities hereabouts are turning to us for the PurityPlus® nitrogen and liquid nitrogen necessary to achieve their research goals. They’ve found us to be a constant, accommodating source of these commodities. And they’ve come to rely not only on our delivering them when they need them, but also on their demonstrable quality, our affordable prices, and the savvy, personalized service of our team.
