Healthcare, Biotech Firms and Research Facilities Rely on PurityPlus® for More Than Specialty Gases


In various Western Michigan industries, PurityPlus® cryogenic refrigerators and storage dewars are as much in demand from GTW as the specialty gases we sell.

Of course, the life sciences count 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 forth. Medical and pharmaceutical concerns naturally use 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 provisions are essential. Other PurityPlus® cryogenic refrigerator and dewar customers include government and university research facilities as well as various biorepositories that specialize in the gathering, 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 substances at the most beneficial temperature. The availability of various hold times, work times, evaporation rates, and other attributes makes it clear there’s a refrigerator for nearly any cryogenic demand.

Our dewars have vacuum-layered walls that provide superior thermal insulation and thus significantly cut the rate at which their contents – either liquid nitrogen or other cryogenic materials – are lost to evaporation.

In addition to these cryogenic hardware, we also offer Western Michigan life science industries …

  • a top-quality whisper valve for cryogenic refrigerators and dewars. This appliance installs effortlessly on the vent valve of these vessels to near-silently reduce the pressure of the compressed gases they hold. Result? Less container damage and fewer lab disruptions.
  • an array of gas cylinder manifold choices including those with automatic changeover. These systems facilitate a continuous flow of gas while automatically changing cylinder or bank priority from the primary source to an auxilliary supply with no fluctuation in pressure.

As necessary as our cryogenic equipment is to healthcare, medicine, and biotechnology, we supply other Western Michigan-area industries with these products as well. By way of illustration, the fabrication of high-end metal products often warrants the use of cryogenics. Utilities depend on cryogenics too – to cool wires and help with the smooth transmission of electric power. In the food industry, cryogenic flash-freezing helps safeguard food nutrients and texture over a prolonged shelf life. And cryogenic freezing is pretty much mandatory in the development of superconductors for, say, MRI machines or use in quantum computing.
