Miles Scientific Silica Gel G 250um 20x20cm (25 plates/box)
Supplier: Miles Scientific P01011
No organic substances are added to these products, thus making them compatible with sulfuric acid charring visualization. These plates are commonly scraped from the glass backing to isolate separated components for other analytical procedures. They are compatible with all organic solvents however, they are not recommended for use in systems containing greater than 20% water because of the solubility of the gypsum binder in aqueous solutions. The "G" stands for Gypsum and indicates that calcium sulfate hemihydrate (CaSO4·1/2H2O), a refined form of gypsum, has been included in the adsorption formulation. Gypsum functions as a binder, improving the cohesion of the adsorbent particles and increasing the adhesion of the layer to the glass substrate.
