WebTraditional dialysis is an alternative buffer exchange technique; however, it has several drawbacks: It relies on slow diffusion and difficult-to-handle dialysis tubing or cassettes. In many cases, during the course of dialysis, the volume in the dialysis tubing increases as a consequence of osmosis, further diluting the sample and requiring a ... WebEquilibrium dialysis uses size-defined membranes to separate the free molecules (i.e., those molecules not bound to plasma proteins at equilibrium state). This type of dialysis mimics an in vivo environment.
