Choosing a dialyzer: What clinicians need to know

WebDialysis membranes are the basic element of a hemodialyzer. Synthetic and natural materials characterized by various fiber arrangements are used in their production. The most up-to-date ones are made of synthetic polymers such as polyamide, phosphatidylserine (PS), polyacrylonitrile-based fiber (PAN … WebTools. In chemistry, dialysis is the process of separating molecules in solution by the difference in their rates of diffusion through a semipermeable membrane, such as dialysis tubing. [1] Dialysis is a common laboratory technique that operates on the same principle as medical dialysis. In the context of life science research, the most common ...
