A staple reagent in organic synthesis and formulation chemistry, Prepacked gravity columns like the Size Exclusion Chromatography Columns Roti ® Dex-25 Medium Grav S, 50 Unit(S) are essential tools for separating and purifying macromolecules based on their molecular weight. These columns utilize a cross-linked dextran matrix with a molecular weight cutoff of 5 kDa and 10 base pairs, allowing for effective separation of proteins and nucleic acids from unwanted low molecular weight factors such as impurities, salts, excipients, and cell debris. With a sample volume capacity of 0.5 ml and an elution volume of 1 ml, these columns offer efficient and reliable purification results. Store them at temperatures between +2 to +25 °C in deionized water with 0.15% ProClin ® 150 for optimal performance.
