We have been serving our clients with a quality tested range of Barium Sulfate Powder in the market. It is a contrast agent. It works by coating the inside of your esophagus, stomach, or intestines that allows them to be seen more clearly on a CT scan or other radiologic (x-ray) examination. Barium Sulfate Powder is used to help diagnose certain disorders of the stomach, esophagus, or intestines.
