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


In various Winona industries, PurityPlus® cryogenic refrigerators and storage dewars are as much sought after from Mississippi Welders Supply Co., Inc. as the specialty gases we provide.

As you can imagine, the life sciences count heavily on this type of equipment. They use it principally to safeguard precious biological materials – human tissue, stem cells, bone marrow, cord blood, and so forth. Medical and pharmaceutical research facilities especially make use of our cryogenic refrigerators and dewars for all manner of medical research, including the creation of vaccines. Then, as you’d expect, there are the blood banks, tissue banks, hospitals, and clinics for whom such tools are crucially important. Other PurityPlus® cryogenic refrigerator and dewar customers comprise government and university research facilities as well as various biorepositories dedicated to the gathering, processing, inventorying, and distribution of biological specimens.

PurityPlus® cryogenic refrigerators come in assorted models and sizes – the better to enable long-term storage of liquid nitrogen and other cryogenic substances at the most beneficial temperature. The availability of various hold times, work times, evaporation rates, and other characteristics makes it clear there’s a refrigerator for practically any cryogenic requirement.

Our dewars have vacuum-layered walls that give you peerless thermal insulation and thus notably reduce the rate at which their contents – either liquid nitrogen or other cryogenic materials – are lost to evaporation.

Rounding out our line of cryogenic apparatuses, we also offer Winona life science firms …

  • a top-quality whisper valve for cryogenic refrigerators and dewars. This instrument installs easily on the vent valve of these containers to quietly reduce the pressure of the compressed gases within. Result? Less container damage and fewer lab disruptions.
  • a number of gas cylinder manifold choices including those with automatic changeover. These systems permit a continuous flow of gas while automatically changing cylinder or bank priority from the origina[l|ting]92] source to an auxilliary supply with no fluctuation in pressure.

As essential as our cryogenic equipment is to healthcare, medicine, and biotechnology, other Winona-area industries benefit from these products as well. Case in point: the making of high-end metal products usually requires 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 imperative in the development of superconductors for, say, MRI machines or use in quantum computing.
