Hollow Fiber Filter

As an important membrane filtration product, hollow fiber filters can be widely used in various areas of pharmaceuticals and life sciences industry, including antibodies, gene and cell therapy, mRNA, human & animal vaccines, blood products, albumin and recombinant proteins, traditional medicine injections, traditional small molecule drugs, biochemical and tissue extracts. Nowadays, hollow fiber is used more and more in pharmaceutical industry for different development stages, including drug screening, process development, and biologics manufacturing.Hollow fiber tangential flow technology is a form of filtration in which the fluid flows parallel to the membrane to generate longitudinal transmembrane pressure, small molecules pass through, large molecules or particles are carried away by the tangential moving fluid, thus extend the filtration time and increase filtration load. It is an effective method for concentration, desalt and buffer exchange of biomolecular solution. Processing volumes can range from a few milliliters to tens of thousands of liters. Duoning provides hollow fiber filters with various MWCOs/pore sizes, mPES and PVDF membrane materials and surface areas for PD to commercial manufacturing, so meets diversified requirements of different applications and process scales.
