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


In various Northern Illinois industries, PurityPlus® cryogenic refrigerators and storage dewars are as much demanded from Weldstar as the specialty gases we manufacture.

Of course, the life sciences count to a great extent on this sort of equipment. They use it principally to preserve sensitive biological materials – human tissue, stem cells, bone marrow, cord blood, and so on. Medical and pharmaceutical researchers especially make use of our cryogenic refrigerators and dewars for all sorts 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 such apparatus is indispensable. Other PurityPlus® cryogenic refrigerator and dewar customers comprise government and university research facilities as well as various biorepositories devoted to the accumulation, processing, inventorying, and dissemination of biological specimens.

PurityPlus® cryogenic refrigerators are offered in a range of models and sizes – the better to enable long-term storage of liquid nitrogen and other cryogenic materials at the proper temperature. The availability of various hold times, work times, evaporation rates, and other characteristics ensures a refrigerator for practically any cryogenic application.

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

As a complement to these cryogenic products, we also supply Northern Illinois life science firms with …

  • a high-quality whisper valve for cryogenic refrigerators and dewars. This appliance installs effortlessly on the vent valve of these containers to quietly relieve the pressure of the compressed gases they hold. Result? Less container damage and fewer lab upsets.
  • a range of gas cylinder manifold choices including those with automatic changeover. These systems allow a continuous flow of gas while automatically changing cylinder or bank priority from the starting source to a supplementary supply with no fluctuation in pressure.

As necessary as our cryogenic equipment is to healthcare, medicine, and biotechnology, other Northern Illinois-area industries use these products as well. By way of illustration, the fabrication of high-end metal products often 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 an extended shelf life. And cryogenic freezing is a requisite in the creation of superconductors for, say, MRI machines or use in quantum computing.
