Precise carbon are supplying to all the leading pharmaceutical companies. Our pinewood charcoal based pharmaceutical grade is best suited for pharmaceutical and bulk drugs industries. Powdered carbon is washed with acid and then repeatedly with water & dried to minimize impurities like ASH contents. IRON contents. ACID soluble. Heavy METALS.Etc. which is extensively used in liquid phase application basically to remove undesired colour, smell and other impurities in many industries such as basic drugs, fine chemicals and pharmaceutical industries. Precise carbon is standards technical specification of washed activated carbon. You are select your require grade and let us know.
