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


In certain Indianapolis industries, PurityPlus® cryogenic refrigerators and storage dewars are as much sought after from American Welding & Gas, Inc. as the specialty gases we supply.

As you can imagine, the life sciences depend heavily on this sort of equipment. They use it mainly to preserve precious biological materials – human tissue, stem cells, bone marrow, cord blood, and the like. Medical and pharmaceutical research facilities especially make use of our cryogenic refrigerators and dewars for all kinds 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 paraphernalia are vital. Other PurityPlus® cryogenic refrigerator and dewar customers consist of government and university research facilities as well as various biorepositories devoted to the gathering, processing, inventorying, and distribution of biological specimens.

PurityPlus® cryogenic refrigerators are offered in a variety of models and sizes – the better to enable long-term storage of liquid nitrogen and other cryogenic matter at the most propitious temperature. The availability of differing hold times, work times, evaporation rates, and other traits ensures a refrigerator for just about any cryogenic demand.

Our dewars have vacuum-layered walls that deliver peerless thermal insulation and thus considerably cut the rate at which their contents – either liquid nitrogen or other cryogenic matter – is lost to evaporation.

Besides these cryogenic equipment, we also supply Indianapolis life science enterprises with …

  • a high-quality whisper valve for cryogenic refrigerators and dewars. This device installs with no effort at all on the vent valve of these canisters to quietly reduce the pressure of the compressed gases they hold. Result? Less container damage and fewer lab upsets.
  • a selection of gas cylinder manifold alternatives including those with automatic changeover. These systems facilitate 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 Indianapolis-area industries avail themselves of these products as well. For example, the making of high-end metal products typically requires the use of cryogenics. Utilities use cryogenics too – to cool wires and assist with the smooth transmission of electric power. In the food industry, cryogenic flash-freezing helps protect food nutrients and texture over a longer shelf life. And cryogenic freezing is imperative in the creation of superconductors for, say, MRI machines or use in quantum computing.
