A constant-volume ultrafiltration technique is described, and details of its assessment presented. The retention characteristics of two membranes were evaluated using molecules of known molecular weight. The technique is rapid, precise, economical of material and yields equilibrium data. In these respects, it compares favourably with conventional techniques such as equilibrium dialysis.
本文描述了一种定容超滤技术，并给出了其评估细节。使用已知分子量的分子评估了两种膜的保留特性。该技术快速、精确、节省材料，并能得出平衡数据。在这些方面，它与平衡透析等传统技术相比具有优势。
