TFF (Tangential Flow Filtration) cassettes are advanced filtration devices used for separating and purifying biomolecules such as proteins and nucleic acids. Operating by directing the feed solution tangentially across the membrane surface, TFF cassettes minimize fouling and maintain high filtration efficiency. Available in various types, including microfiltration and ultrafiltration, they cater to a wide range of applications in bioprocessing, pharmaceuticals, and research labs. TFF cassettes are valued for their high throughput, scalability, and ability to handle diverse samples and volumes.
