ResumoDextran, a glucose polymer, is used as a blood plasma volume expander and for the production of iron dextran. For the removal of low molecular weight material from dextran aqueous solutions, and the purification and concentration of these solutions, two laboratory-scale and two large-scale ultrafiltration units were used with several membranes. The results showed that low molecular weight dextrans and soluble impurities can be removed successfully from dextran solution by ultrafiltration. Dextran solutions were concentrated from 20 g l−1 up to 350 g l−1.
