Produced for stability across temperature-sensitive applications, the Size Exclusion Chromatography Columns Roti ® Dex-25 Medium Grav Xxl offer efficient purification of protein or nucleic acid solutions. These prepacked gravity columns, with a 5 kDa 10 Boiling Point MWCO, utilize a spherical porous gel filtration medium made of cross-linked dextran. The Grav XXL version features particle sizes ranging from 50-150 µm dry and 85-260 µm wet, allowing for a sample volume of up to 10 ml. The elution volume is 14 ml, and the storage buffer is deionized water with 0.15% ProClin ® 150. These columns are designed to effectively remove unwanted low molecular weight factors, such as impurities, salts, excipients, markers, cell debris, etc., ensuring high-quality results within the specified temperature range (+2 to +25 °C).
