We are a reliable source of metallic mercury for a wide variety of users including chlorine/caustic soda, switch, semi-conductor, fluorescent light and dental amalgam manufacturers, research laboratories, and the process and control industries.We clean our mercury by distilling it four times in continuous stages under high vacuum and controlled low temperatures to achieve the highest commercial grade of mercury available.
