Tangential Flow Filtration (TFF) is a widely used separation and purification technology in the pharmaceutical, biotechnology, and life sciences industries. A TFF System enables efficient concentration, diafiltration, and purification of biomolecules while maintaining product integrity and high recovery. Intech Analyticals offers advanced TFF systems designed to meet the growing demands of modern bioprocessing and laboratory workflows.
What Is a TFF System?
A TFF System, also known as crossflow filtration, is a membrane-based filtration technique where the feed solution flows tangentially across the membrane surface. Unlike traditional dead-end filtration, TFF continuously sweeps away retained particles, minimizing membrane fouling and enabling longer, more efficient filtration runs.
TFF systems are commonly used for processing proteins, antibodies, vaccines, enzymes, nucleic acids, and other biological products.
Principle of Tangential Flow Filtration
In a TFF System, the feed stream flows parallel to the membrane surface under controlled pressure. Smaller molecules and solvents pass through the membrane as permeate, while larger molecules are retained and recirculated in the system.
By adjusting parameters such as transmembrane pressure, flow rate, and membrane pore size, TFF allows precise separation and concentration of target molecules. This controlled and gentle process ensures high product quality and reproducibility.
Key Components of a TFF System
A modern TFF System from Intech Analyticals consists of several integrated components that ensure consistent and reliable performance:
-
TFF membranes (ultrafiltration or microfiltration)
-
Pump system for controlled flow
-
Pressure sensors and flow meters
-
Tubing and connectors
-
Filtration cassette or hollow fiber modules
-
Automated control system with data logging
These components work together to deliver efficient filtration with minimal product loss.
