Product Description
Dextran Gel G-25 is a bead-shaped gel containing a large number of hydroxyl groups, which swells easily in water and electrolyte solutions. The G-type dextran gels have varying degrees of crosslinking, leading to differences in their swelling capacity and fractionation range. Dextran Gel G-25 is available in different particle sizes: superfine particles for high-resolution column and thin-layer chromatography, and coarse and medium grades for preparative chromatography, which allows for high flow rates at lower pressures. Coarse grade is also suitable for batch processes. Dextran gels are insoluble in all solvents (unless chemically degraded) and are stable in water, salt solutions, organic solvents, bases, and weak acids. However, they are hydrolyzed in strong acids, and prolonged exposure to oxidants should be avoided as it can damage the gel. Dextran gels do not melt and can be sterilized in the wet state at neutral pH or autoclaved at 120°C for 30 minutes without affecting their chromatographic properties. When dry, heating above 120°C will initiate caramelization. The mechanical strength of dextran gels depends on the degree of crosslinking.
