TFF Cassettes
Cobetter Consieve®️ Cassettes have high retention efficiencies and are easy to install and clean. Available in a wide range of configurations. The design allows easy scale up per specific process requirements.
Overview
What is Tangential Flow Filtration?
Tangential flow filtration is a membrane technology for concentration, dialysis and separation, usually retaining the molecular weight range of 1-1000kDa. Unlike traditional vertical filtration, in tangential flow filtration, the fluid flows tangentially across the membrane surface and the transmembrane pressure difference created by the fluid presses a portion of the solution against the filter membrane, while the retained portion circulates back through the system.
During the whole process, the liquid flows continuously through the membrane surface, so that the membrane surface is not easy to form a gel layer, the particles in the liquid will not quickly block the membrane, maintaining a stable filtration speed.

How to use a TFF Cassette?
Rinse before use
Before using a new or used-and-stored cassette, rinse the storage solution from the TFF cassette first.
Measuring Water Flux
Measuring water flux involves measuring the flow of water through the TFF cassette’s membrane under controlled conditions. Convert the measuring value into standard water flux, which is an indicator of the performance of the TFF cassette.
Integrity Test
Before using your TFF cassette and holder to process product, test the cross-flow system to ensure it does not leak. Then make the integrity test of the cassette.
