Process Dialysis
Process Scale Dynamic Dialysis:

Large-volume Process Dialysis is an emerging technology driven by the increasing demand for gentle and consistent multi-batch purification at the production scale. While Laboratory Dialysis for research and analytical testing typically involves static stirring of small volumes for sample prep or solute release studies. Process Dialysis facilitates dynamic buffer flow around the membrane-encased sample to increase purification efficiency and improve large buffer handling for the production of fragile proteins, viscous fluids and polymer gels, such as hyaluronic acid.

Spectra/Por® Products Designed for Process Dialysis

Repligen offers top quality dialysis membrane, Turnkey systems and small volume devices to make sample analysis easy.

Process Scale Dynamic Dialysis Tank Systems

Repligen has developed processing flow-path components that quickly and easily assemble into a complete dynamic dialysis system for handling buffer volumes up to 500 liters. The system was designed to optimize gentle buffer flow and efficiency dialysis
