Dextran is a high-molecular-weight glucose polymer with an average relative molecular mass ranging from several thousand to several hundred thousand Daltons. Low molecular weight dextran typically refers to dextran with a weight-average molecular weight below 20,000 Da, which functions to improve microcirculation, increase plasma colloid osmotic pressure, and exert osmotic diuretic effects. In recent years, to reduce production costs and enhance product quality, novel membrane separation technologies such as hollow fiber ultrafiltration and nanomembrane technology have been applied in the ultrafiltration purification, nanoconcentration, and purification processes of iron dextran hydrolysate.

      Membrane separation technology is a physical concentration technique that performs macromolecular ultrafiltration and impurity removal of iron dextran hydrolysate at the molecular level, achieving product purification and filtration. The refined solution is further purified and concentrated using a nanomembrane filter, enriching the target components while allowing small molecules and inorganic salts to permeate, thereby achieving bidirectional purification. Jiahe Filtration Design provides hollow fiber membrane ultrafiltration systems and nanomembrane concentrators for iron dextran, which can be customized based on user material properties, volume, and processing time requirements. The systems are constructed from SUS304 or 316L materials, complying with SC and GMP certification standards.
