NettetVirosart ® HF combines the highest level of virus safety with flexible capacities for virus retentive filtration of monoclonal antibodies, antibody fragments or small recombinant proteins. The filter targets both non-enveloped viruses, such as MVM and vesivirus, and large enveloped viruses, such as MuLV, providing the full range of coverage ... 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.
