The Use of Liquid Nitrogen in Northern Illinois Laboratory Research


Weldstar has been producing and distributing PurityPlus® liquid nitrogen for Northern Illinois-area laboratory use from the beginning. The one essential characteristic that makes this commodity so [[desi|[prefe]7]rable in such a wide range of laboratory applications – most notably as a refrigerant – is its ability to hold temperatures appreciably lower than the freezing point of water.

An earlier blog we’ve posted limns the use of nitrogen in food processing. In its compact, easily transportable liquid form (which doesn’t need pressurization), we supply it for such laboratory applications as …

  • cryogenics – involving the realization and analysis 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 especially low temperatures in order to revive them and reanimate them at some point in the future; also as a way to cryoconserve genetic materials;
  • energy storage (being a medium for it);
  • ensuring that all types of scientific detection instruments function more efficiently; and
  • achieving lower pressures in laboratory vacuum systems.

As a coolant, liquid nitrogen is principally applied by the laboratories we serve …

  • to effect superconductivity in high-temperature superconductors;
  • to sustain the liquid helium cooling systems of high-field superconducting magnets, e.g. 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 produce 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, scarcely cover liquid nitrogen’s use in the laboratory. Our Northern Illinois customers frequently find their own, unique uses for it, just as they do for nitrogen in its gaseous state – which, of course, we also provide.

The upshot of it is, an increasing 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 necessary to achieve their research goals. They’ve found us to be a steady, ready source of these commodities. And they’ve come to rely not only on our delivering them when they need them, but also on their verifiable quality, our reasonable prices, and the smart, personalized service of our staff.
