Economic Analysis of Single Use Tangential Flow Filtration for Biopharmaceutical Applications

Tangential flow filtration (TFF) is a common processing step in concentration and diafiltration (buffer exchange) operations in the downstream processing of biopharmaceutical products. Using a pre-sanitised, disposable TFF membrane makes it possible to reduce the number of process steps and thus reduce labor by 50% or more and reduce buffer and water usage by 75% or more. In addition to the cost savings realised from the reduced labor and buffer usage, single use TFF can increase productivity, by >45% in many cases. This article outlines an economic model for comparing the costs of reusable and single?use TFF in biopharmaceutical applications.
