The Use of Liquid Nitrogen in Fresno Laboratory Research

 

Fresno Oxygen & Welding Supplies/Barnes Welding Supply has been producing and selling PurityPlus® liquid nitrogen for Fresno-area laboratory use since we first opened our doors. What makes this commodity so beneficial in all sorts of laboratory activities – particularly as a refrigerant – is its capability of holding temperatures conspicuously lower than the freezing point of water.

A previous blog we’ve posted discusses the use of nitrogen in food processing. In its dense, easily movable liquid form (which doesn’t demand pressurization), we supply it for laboratory applications as varied as …

  • cryogenics – includeing the realization and examination 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 ”reawaken” them and reanimate them sometime later; also as a way to cryoconserve genetic assets;
  • energy storage (serving as a mechanism for it);
  • helping all sorts of scientific detection instruments function more efficiently and effectively; and
  • producing lower pressures in laboratory vacuum systems.

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

  • to achieve superconductivity in high-temperature superconductors;
  • to preserve the liquid helium cooling systems of high-field superconducting magnets, such as 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 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, barely scratch the surface of liquid nitrogen’s use in the laboratory. Our Fresno customers commonly discover their own, unique uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also supply.

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 needed to realize their research goals. They’ve found us to be a steady, accommodating 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 deft, personalized service of our team.
