TFF Cassette Holders
To withstand the forces required for tangential flow filtration (TFF), a robust cassette holder is required. The holder and gaskets also help facilitate the flow of liquid through the feed, retentate, and permeate lines.
Sartorius offers a range of TFF holders to accommodate different cassette sizes, flow rates, and membrane areas—from small-scale formats (Sartocon® Holders) to large-scale cubical formats (Sartoflow® Holders).
