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


In various Portland industries, PurityPlus® cryogenic refrigerators and storage dewars are as much in demand from Cryo-Source as the specialty gases we sell.

As you can imagine, the life sciences depend very much on this type of equipment. They use it primarily to safeguard delicate biological materials – human tissue, stem cells, bone marrow, cord blood, and such. Medical and pharmaceutical concerns specifically make use of 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 dissemination of biological specimens.

PurityPlus® cryogenic refrigerators come in a number of models and sizes – the better to permit long-term storage of liquid nitrogen and other cryogenic materials at the most beneficial temperature. The availability of various hold times, work times, evaporation rates, and other attributes ensures a refrigerator for almost any cryogenic need.

Our dewars are designed with vacuum-layered walls that provide unbeatable thermal insulation and thus markedly limit the speed at which their contents – either liquid nitrogen or other cryogenic matter – is lost to evaporation.

Besides these cryogenic apparatuses, we also offer Portland life science industries …

  • a top-quality whisper valve for cryogenic refrigerators and dewars. This appliance installs with no effort at all on the vent valve of these canisters to quietly relieve the pressure of the compressed gases they hold. Result? Less container damage and fewer lab upsets.
  • a range of gas cylinder manifold choices including those with automatic changeover. These systems provide a continuous flow of gas while automatically changing cylinder or bank priority from the origina[l|ting]92] source to an extra supply with no fluctuation in pressure.

As crucial as our cryogenic equipment is to healthcare, medicine, and biotechnology, we furnish other Portland-area industries with these products as well. Case in point: the making of high-end metal products often requires the use of cryogenics. Utilities make use of cryogenics too – to cool wires and aid in 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 essential in the development of superconductors for, say, MRI machines or use in quantum computing.
