NW Dex Series Gel Filtration Pre-packed Columns

Based on cross-linked porous hydrophilic agarose microspheres, this resin leverages size exclusion molecular sieving effects: large molecules that cannot enter the gel pores elute first, while small molecules that penetrate the pores elute later. Separation is achieved through a purely physical, gentle mechanism driven solely by differences in molecular hydrodynamic radius.

Product Description

NW Dex® G-25 series dextran gels are chromatography media designed for the separation and purification of biomolecules. Produced from dextran and cross-linked to form dextran microspheres, they feature a hydrophilic, porous structure. These resins are commonly used for buffer exchange, desalting, and removal of small molecules from biological samples such as viruses, proteins, polysaccharides, and nucleic acids. They are also suitable for the separation and purification of peptides, oligonucleotides, antibiotics, synthetic drugs, and natural products, as well as for the purification of nanomaterials in chemical processing and wastewater treatment in environmental applications.

NW Dex™ G-25 is available in four types based on gel particle size:

NW Dex® G-25 C (coarse particles)

NW Dex® G-25 M (medium particles)

NW Dex® G-25 F (fine particles)
