Abstract
RAPIDITY and completeness of dialysis are favoured by a high concentration gradient at the membrane, which, in turn, depends on rapid transport of dialysable material to and from the membrane. At the same time, it is desirable in certain studies to obtain the permeate in the smallest possible volume, to simplify manipulation and to minimize the relative magnitude of analytical blank values. The apparatus is based on these considerations ; it is particularly suited for dialysis of suspended materials and can be used at temperatures between 0 and 100° C. We have employed it in the study of the soluble components of bacteria (in connexion with work conducted under a research contract (NONR-244(00) with the Office of Naval Research), the amount of dialysable material varying between 0.l and 40 mgm. of total nitrogen per experiment.
