The Use of Liquid Nitrogen in Winona Laboratory Research


Mississippi Welders Supply Co., Inc. has been producing PurityPlus® liquid nitrogen for Winona-area laboratory use from our earliest days. What makes this commodity so advantagous in all sorts of laboratory applications – most notably as a refrigerant – is its capability of maintaining temperatures conspicuously lower than the freezing point of water.

A previous blog we’ve posted outlines the use of nitrogen in food processing. In its dense, readily movable liquid form (which needn’t be pressurized), we deliver it for laboratory applications as diversified as …

  • cryogenics – involving the production and study of low temperature extremes and how materials behave at such temperatures;
  • cryonics – the long-term protection of biological tissue (blood, reproductive cells, surgical samples, even human bodies) at unusually low temperatures in order to resuscitate them and reanimate them sometime in the future; also as a way of cryoconserving genetic resources;
  • energy storage (being a mechanism for it);
  • ensuring that all kinds of scientific detection instruments work more effectively; and
  • generating lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is most notably used 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 especially low temperature;
  • in cooling baths and other testing situations designed 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-encompassing as they are, hardly account for liquid nitrogen’s use in the laboratory. Our Winona 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, an increasing number of scientific, medical, and industrial research facilities in these parts are calling on us for the PurityPlus® nitrogen and liquid nitrogen they require in order to realize their research goals. They’ve found us to be a constant, ready source of these commodities. And they’ve come to depend not only on our providing them when they need them, but also on their demonstrable quality, our affordable prices, and the stellar, personalized service of our team.
