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


In certain Pittsburgh industries, PurityPlus® cryogenic refrigerators and storage dewars are as much demanded from Greco Gas as the specialty gases we supply.

Of course, the life sciences depend very much on this sort of equipment. They use it most often to preserve precious biological materials – human tissue, stem cells, bone marrow, cord blood, and the like. Medical and pharmaceutical researchers specifically make use of our cryogenic refrigerators and dewars for all manner of medical research, including the making of vaccines. Then, as you’d expect, there are the blood banks, tissue banks, hospitals, and clinics for whom such paraphernalia are indispensable. Other PurityPlus® cryogenic refrigerator and dewar customers consist of government and university research facilities as well as various biorepositories that specialize in the gathering, processing, inventorying, and dispensation of biological specimens.

PurityPlus® cryogenic refrigerators come in assorted models and sizes – the better to permit long-term storage of liquid nitrogen and other cryogenic substances at the proper temperature. The availability of various hold times, work times, evaporation rates, and other attributes ensures a refrigerator for just about any cryogenic demand.

Our dewars have vacuum-layered walls that deliver outstanding thermal insulation and thus strikingly limit the rate at which their contents – either liquid nitrogen or other cryogenic materials – are lost to evaporation.

In addition to these cryogenic products, we also offer Pittsburgh life science enterprises …

  • a top-quality whisper valve for cryogenic refrigerators and dewars. This instrument installs with no effort at all on the vent valve of these vessels to alleviate – almost without sound – the pressure of the compressed gases inside. Result? Less container damage and fewer lab hassles.
  • a variety 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 origina[l|ting]92] source to an extra supply with no fluctuation in pressure.

As indispensable as our cryogenic equipment is to healthcare, medicine, and biotechnology, we furnish other Pittsburgh-area industries with these products as well. For instance, the manufacture of high-end metal products frequently involves the use of cryogenics. Utilities make use of 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 longer shelf life. And cryogenic freezing is imperative in the development of superconductors for, say, MRI machines or use in quantum computing.

No matter your field or application, get the preferred cryogenic equipment and gases for it from Greco Gas, your Pittsburgh PurityPlus® Partner.
