Spherical Silica Gel, Premium Rf has a porosity of 70A, particle distribution of 75-200um, and a quantity of 2.5kg. Spherical Silica Gel, Premium Rf when compared to granular silica gels show an increase loading (up to 30% more), greater reproducibility of process, sharper peaks and cost savings (less solvent consumption and labor), longer bed lifetime (decrease cost of labor and silica consumption), and better chromatographic results. This high-purity spherical silica gel is ideal for classical column chromatography, industrial scale LC, and batch adsorption applications. Sorbtech spherical gravity silica gels function through hydrophilic interactions with more polar compounds which are generally retained than more lipophilic substances, making them ideally suited for the purification of chemical synthesis intermediates, oils, fats and natural products (vitamins, flavors, fragrances, etc.)
