Healthcare, Biotech Firms and Research Facilities Turn to PurityPlus® for More Than Specialty Gases


In certain Southern California industries, PurityPlus® cryogenic refrigerators and storage dewars are as much demanded from WestAir Specialty Gases and Equipment as the specialty gases we provide.

Of course, the life sciences depend to a great extent on this sort of equipment. They use it most often to maintain sensitive biological materials – human tissue, stem cells, bone marrow, cord blood, and so forth. Medical and pharmaceutical enterprises especially use our cryogenic refrigerators and dewars for all manner of medical research, including the development of vaccines. Then, as you’d expect, there are the blood banks, tissue banks, hospitals, and clinics for whom this kind of equipment is indispensable. Other PurityPlus® cryogenic refrigerator and dewar customers consist of government and university research facilities as well as various biorepositories dedicated to the accumulation, processing, inventorying, and dissemination of biological specimens.

PurityPlus® cryogenic refrigerators are offered in assorted models and sizes – the better to permit long-term storage of liquid nitrogen and other cryogenic matter at the most beneficial temperature. The availability of differing hold times, work times, evaporation rates, and other features makes it clear there’s a refrigerator for almost any cryogenic demand.

Our dewars are constructed with vacuum-layered walls that provide exceptional thermal insulation and thus considerably lower the rate at which their contents – either liquid nitrogen or other cryogenic matter – is lost to evaporation.

As a complement to these cryogenic apparatuses, we also supply Southern California life science industries with …

  • a high-quality whisper valve for cryogenic refrigerators and dewars. This device installs with no effort at all on the vent valve of these vessels to near-silently alleviate the pressure of the compressed gases inside. Result? Less container damage and fewer lab hassles.
  • a range of gas cylinder manifold alternatives including those with automatic changeover. These systems make possible a continuous flow of gas while automatically changing cylinder or bank priority from the primary source to an additional supply with no fluctuation in pressure.

As indispensable as our cryogenic equipment is to healthcare, medicine, and biotechnology, we furnish other Southern California-area industries with these products as well. By way of illustration, the fabrication of high-end metal products usually requires the use of cryogenics. Utilities have a need for cryogenics too – to cool wires and facilitate the smooth transmission of electric power. In the food industry, cryogenic flash-freezing helps protect food nutrients and texture over a prolonged shelf life. And cryogenic freezing is a requisite in the creation of superconductors for, say, MRI machines or use in quantum computing.

Regardless of your field or application, get the best cryogenic equipment and gases for it from WestAir Specialty Gases and Equipment, your Southern California PurityPlus® Partner.
