How to measure the porosity of hollow fiber membrane

NettetThree primary means of integrity determination are as follows: A.Close the air/gas inlet, then monitor the pressure gauge for a significant decrease in pressure. B.(For cartridges with clear housings) Observe the evolution of a steady stream of bubbles when the cartridge is filled with liquid. Nettet27. mai 2024 · About. Focusing on solutions for the pharmaceutical industry globally and bridging the gap between manufacturers and end … NettetHollow fiber (HF) ultrafilters are integrity testable using a constant air pressure diffusion test. Diffusion testing checks the integrity of the membrane but not the pore size. Diffusion testing measures the amount of air (cc/min) that diffuses through an integral “wetted” membrane of given area, thickness and porosity. human rights regulations dbhds
