Efficient separation and cleanliness with tangential flow filtration (TFF)

Tangential flow filtration (TFF)

Tangential flow filtration, or TFF, is used in the biopharmaceutical industry to separate and purify biomolecules such as proteins, DNA and viruses. The method applies pressure to a solution across a membrane, allowing smaller molecules to pass through while retaining larger molecules.

TFF enables the efficient separation of target molecules from impurities, resulting in highly pure products that meet strict quality standards.

Continuous filtration for increased efficiency

One of the main advantages of TFF over other filtration methods is its ability to operate continuously. This leads to higher productivity and shorter processing times. Unlike traditional filtration methods, which can clog or require frequent changes, TFF's tangential flow design minimizes clogging. It also allows for longer operating times. Therefore, TFF is a cost-effective and efficient option for bioprocess applications.

Advanced TFF technology: scalability and automation

Recent advances in TFF technology have focused on improving scalability and automation. Manufacturers are developing TFF systems that can handle larger volumes of biomolecules while maintaining high purity and yield levels. In addition, the integration of artificial intelligence and machine learning algorithms into TFF systems has enabled real-time monitoring and control, optimizing process parameters for improved performance and reproducibility.

Levitronix pumps: Optimal precision and reliability

In the case of tangential flow filtering (TFF), the use of a Levitronix pumping system several advantages. Levitronix pumps are known for their precision, reliability and efficiency, making them ideal for TFF applications. A key benefit of using a Levitronix pumping system in TFF is its ability to provide accurate and consistent flow rates. This is critical to maintaining the optimal conditions required for effective filtration and separation of biomolecules. The precise control offered by Levitronix pumps ensures that the TFF process is carried out with high reproducibility, leading to consistent and reliable results.

Gentle biomolecule handling

Another advantage of using a Levitronix pumping system in TFF is its gentle handling of biomolecules. Levitronix pumps utilize magnetic levitation technology, eliminating the need for mechanical bearings or seals that can cause shear stress or damage sensitive biomolecules. This gentle pumping action helps preserve the integrity and bioactivity of the biomolecules being filtered, resulting in higher product yield and purity.

In addition, Levitronix pumping systems are known for their low maintenance requirements and long service life. The lack of contact between moving parts in Levitronix pumps reduces the risk of contamination and wear, leading to extended pump life and minimal maintenance downtime.
