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


In various Atlanta, GA industries, PurityPlus® cryogenic refrigerators and storage dewars are as much demanded from Sidney Lee Medical & Scientific Gases as the specialty gases we produce.

Of course, the life sciences count very much on this type of equipment. They use it most often to maintain delicate biological materials – human tissue, stem cells, bone marrow, cord blood, and so on. Medical and pharmaceutical concerns specifically employ 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 this sort of equipment is vital. Other PurityPlus® cryogenic refrigerator and dewar customers consist of government and university research facilities as well as various biorepositories that specialize in the collection, processing, inventorying, and dissemination of biological specimens.

PurityPlus® cryogenic refrigerators come in assorted models and sizes – the better to permit long-term storage of liquid nitrogen and other cryogenic materials at the most propitious temperature. The availability of various hold times, work times, evaporation rates, and other characteristics ensures a refrigerator for just about any cryogenic requirement.

Our dewars have 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.

Besides these cryogenic products, we also offer Atlanta, GA life science firms …

  • a top-quality whisper valve for cryogenic refrigerators and dewars. This device installs easily on the vent valve of these vessels to near-silently alleviate the pressure of the compressed gases inside. Result? Less container damage and fewer lab upsets.
  • a range 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 starting source to a secondary supply with no fluctuation in pressure.

As important as our cryogenic equipment is to healthcare, medicine, and biotechnology, we supply other Atlanta, GA-area industries with these products as well. By way of illustration, the fabrication of high-end metal products typically entails the use of cryogenics. Utilities make use of 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 longer shelf life. And cryogenic freezing is imperative in the development of superconductors for, say, MRI machines or use in quantum computing.

Whatever your field, whatever your application, get the favored cryogenic equipment and gases for it from Sidney Lee Medical & Scientific Gases, your Atlanta, GA PurityPlus® Partner.
