A simple procedure for making a series of membranes of graded pore sizes is presented with data for permeability of the membrane series to water and to colloidal sols of known particle sizes. A convenient ultrafiltration apparatus for operation under aseptic conditions is described.
Permporometry IS a method by which the characterlstlcs of the mterconnectmg ‘active’ pores of an ultrafiltration membrane can be measured It 1s these ‘active’ pores that are responsible for the actual membrane performance Apphcatlon of permporometry on different membrane types, including ceramic as well as polymeric membranes, shows that the method can provide obJectwe mformatlon on the ‘active...
comIn the case of pharmaceutical processes, the presence of preservatives can be problematic and the quantity is subject to stringent standards. So, the aim of this study is to quantify the removal of glycerin contained in ultrafiltration flat sheet membranes by filtration and soaking. This is carried out over a wide range of membranes with different characteristics. The selected flat sheet mem...
