Troubleshooting Tangential Flow Filtration
Tangential flow filtration (TFF) is commonly used to concentrate and dialyze solutes. It generally involves the circulation of the feed solution over a filter surface. This article presents a brief overview of the principles governing TFF, and offers an empirical approach to optimizing operating conditions for mammalian cell-culture clarification applications. clarification, this optimization is complicated by the fact that the cells are damaged by high feed flowrates.
