Dynamic dialysis systems

Dynamic dialysis is an exciting new technology driven by increasing demand for gentle and consistent multi-batch large-volume purification. It aims to facilitate dynamic buffer flow around the membrane-encased sample to increase purification efficiency and to improve large buffer handling. Ideal for the production of fragile proteins, viscous fluids and polymer gels, such as hyaluronic acid, dynamic dialysis products include lab-scale to process-scale recircualtion tanks, systems, membranes and tubing.
