Size Exclusion Column

Description

G Biosciences offers this Size Exclusion Column for chromatographic separations based on molecular size. Also known as gel filtration or gel permeation chromatography, this technique is used to fractionate biomolecules like proteins, nucleic acids, and polysaccharides, or to separate polymers. The column is packed with a porous stationary phase. Larger molecules that cannot enter the pores elute first, while smaller molecules that travel through the pore network elute later. This process is primarily used for purification, buffer exchange, desalting, and molecular weight estimation. The column is compatible with standard liquid chromatography systems and is suitable for analytical or preparative-scale applications in biochemistry, molecular biology, and polymer science.
