The PF-F degasification mechanism removes gases dissolved in liquids through a tube-shaped gas-permeable membrane made of polytetrafluoroethylene (PTFE). Specifically, gases dissolved in the liquid flowing through the tube are removed by the pressure difference of the gases inside and outside of the tube created by a vacuum on the outside of the tube as shown in the diagram below. Watch this video to see how the process works.


Because liquid randomly flows over the hollow fibers during external perfusion, dissolved gasses touch the membrane more frequently. Therefore, degasification performance is higher than in the Internal Perfusion Series (PF Series). Also, a lower pressure drop means that larger modules can be used. Watch this video to see how the process works.
