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


In a number of Pittsburgh industries, PurityPlus® cryogenic refrigerators and storage dewars are as much demanded from Butler Gas Products as the specialty gases we supply.

Of course, the life sciences rely heavily on this kind of equipment. They use it mostly to safeguard delicate biological materials – human tissue, stem cells, bone marrow, cord blood, and so on. Medical and pharmaceutical labs especially make use of our cryogenic refrigerators and dewars for all kinds 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 this kind of equipment is critically important. Other PurityPlus® cryogenic refrigerator and dewar customers are government and university research facilities as well as various biorepositories that specialize in the amassing, 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 most beneficial temperature. The availability of various hold times, work times, evaporation rates, and other characteristics ensures a refrigerator for almost any cryogenic application.

Our dewars are built with vacuum-layered walls that give you matchless thermal insulation and thus notably reduce the speed at which their contents – either liquid nitrogen or other cryogenic materials – are lost to evaporation.

Rounding out our line of cryogenic apparatuses, we also offer Pittsburgh life science researchers …

  • a top-quality whisper valve for cryogenic refrigerators and dewars. This appliance installs with no effort at all on the vent valve of these vessels to near-silently reduce the pressure of the compressed gases within. Result? Less container damage and fewer lab disturbances.
  • a range of gas cylinder manifold choices including those with automatic changeover. These systems provide a continuous flow of gas while automatically changing cylinder or bank priority from the starting source to an extra supply with no fluctuation in pressure.

As important as our cryogenic equipment is to healthcare, medicine, and biotechnology, we supply other Pittsburgh-area industries with these products as well. Case in point: the making of high-end metal products generally warrants 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 prolonged shelf life. And cryogenic freezing is pretty much mandatory in the creation of superconductors for, say, MRI machines or use in quantum computing.

Whatever your field, whatever your application, get the favored cryogenic equipment and gases for it from Butler Gas Products , your Pittsburgh PurityPlus® Partner.
