Tangential Flow Filtration (TFF) Market Definition
Tangential flow filtration (TFF), also known as crossflow filtration, is a membrane-based separation technique where a liquid solution flows tangentially across the surface of a filter membrane. This method allows smaller molecules and solvents to pass through the membrane (permeate), while larger particles like proteins, cells, or other macromolecules are retained (retentate). The primary purpose of TFF is to concentrate, clarify, and purify biological products such as proteins, enzymes, antibodies, and cell cultures.
The tangential flow filtration market consists of sales, by entities (organizations, sole traders and partnerships), of tangential flow filtration that are used extensively in biopharmaceutical and diagnostic workflows. TFF is employed during downstream processing of biologics, vaccine manufacture, viral vector purification, cell‑therapy operations and academic research. This technique offers high throughput, scalability, gentle processing and reduced fouling compared to dead‑end filtration.
