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


In various Columbus industries, PurityPlus® cryogenic refrigerators and storage dewars are as much in demand from Delille Oxygen Company as the specialty gases we produce.

Of course, the life sciences count heavily on this sort of equipment. They use it most often to protect sensitive biological materials – human tissue, stem cells, bone marrow, cord blood, and such. Medical and pharmaceutical entities 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 such apparatus is crucial. Other PurityPlus® cryogenic refrigerator and dewar customers are government and university research facilities as well as various biorepositories that specialize in the collection, processing, inventorying, and dispensation of biological specimens.

PurityPlus® cryogenic refrigerators are offered in various models and sizes – the better to enable long-term storage of liquid nitrogen and other cryogenic matter at the most beneficial temperature. The availability of different hold times, work times, evaporation rates, and other traits ensures a refrigerator for almost any cryogenic requirement.

Our dewars have vacuum-layered walls that give you exceptional thermal insulation and thus considerably reduce 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 Columbus life science enterprises …

  • a top-quality whisper valve for cryogenic refrigerators and dewars. This device installs easily on the vent valve of these containers to quietly reduce the pressure of the compressed gases inside. Result? Less container damage and fewer lab upsets.
  • a selection of gas cylinder manifold choices including those with automatic changeover. These systems enable a continuous flow of gas while automatically changing cylinder or bank priority from the first source to a supplemental supply with no fluctuation in pressure.

As important as our cryogenic equipment is to healthcare, medicine, and biotechnology, other Columbus-area industries employ these products as well. For instance, the manufacture of high-end metal products typically requires the use of cryogenics. Utilities rely on 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 a requisite in the production of superconductors for, say, MRI machines or use in quantum computing.
