Superman's laboratory is one of the most highly advanced science labs in the world. Here he studies the substance known as Kryptonite in the hope of finding a way to reverse its effects on Kryptonian physiology. He also uses the lab in an attempt to cure Daxamite lead poisoning, so that he might one day free his friend Mon-El and from the Phantom Zone. Superman also uses the lab in the hopes of finding a way to restore the people of Kandor to their normal size.
