Silica Gel, Enhanced Grade is a high purity silica 60 for use in the laboratory or in production. The "tight" particle distribution provides a high resolution chromatographic separation. The silica gel has a porosity of 60A, particle distribution of 40-63um (230x400mesh), and a quantity of 5kg. This silica gel is ideal for packing traditional flash chromatography columns. It is commonly used for the purification of natural products, foods, cosmetics, pharmaceuticals, and nutraceuticals.
