Tangential Flow Filtration(TFF)

Tangential Flow Filtration (TFF) is widely used in biopharmaceutical processes for sample concentration, buffer exchange, and impurity removal.
By maintaining continuous flow across the membrane surface, TFF reduces membrane fouling and supports high flux, efficient processing, and scalable production.
LePure Biotech provides TFF solutions including PES membrane cassettes and hollow fiber modules, supporting applications from laboratory development to pilot and commercial manufacturing.

  • High Flux and Efficient Processing: Continuous crossflow operation helps reduce membrane fouling and supports stable filtration performance.
  • Low Product Loss：Low protein adsorption, small residual volume
  • Long Service Life：Chemically resistant, reusable
