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


In certain industries, cryogenic refrigerators and storage dewars are as much in demand from our more than 150 nationwide PurityPlus® partners as the specialty gases we sell.

Of course, the life sciences depend heavily on this kind of equipment. They use it primarily to preserve delicate biological materials – human tissue, stem cells, bone marrow, cord blood, and the like. Medical and pharmaceutical concerns specifically employ 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 equipment is indispensable. Other PurityPlus® cryogenic refrigerator and dewar customers include government and university research facilities as well as various biorepositories that specialize in the collection, processing, inventorying, and distribution of biological specimens.

PurityPlus® cryogenic refrigerators come in a variety 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 attributes ensures a refrigerator for virtually any cryogenic need.

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

Besides these cryogenic products, we also supply life science industries with …

  • a high-quality whisper valve for cryogenic refrigerators and dewars. This device installs easily on the vent valve of these containers to quietly relieve the pressure of the compressed gases within. Result? Less container damage and fewer lab disruptions.
  • a variety of gas cylinder manifold options including those with automatic changeover. These systems provide a continuous flow of gas while automatically changing cylinder or bank priority from the original source to an additional supply with no fluctuation in pressure.

As important as our cryogenic equipment is to healthcare, medicine, and biotechnology,  we supply other industries with these products as well. For instance, the manufacture of high-end metal products often entails the use of cryogenics. Utilities use cryogenics too – to cool wires and aid in the smooth transmission of electric power. In the food industry, cryogenic flash-freezing helps preserve food nutrients and texture over a longer shelf life. And cryogenic freezing is essential in the creation of superconductors for, say, MRI machines or use in quantum computing.
