Liquid-Liquid Porometry of Viresolve® Pro Membrane

A liquid-liquid porometry (LLP) test was developed to characterize the pore size distribution of Viresolve® Pro membrane. Data generated by this test supports the understanding of the size-based virus removal mechanism of the filter. The LLP test also is used at-line during membrane casting. Process control based on LLP results improves membrane consistency.
