Metal filter, part of copper pressure vessel, used by Frederick Power (1853-1927)

Perforated metal disc, likely a filter and part of copper pressure vessel, used in the laboratory of Frederick Power (1853-1927), American Chemist and Chief Scientist at Wellcome Chemical Research laboratories, 1896-1914

This copper vessel was likely part of distillation apparatus used in chemical laboratory experiments that required heat and pressure. It was used in the laboratory of Frederick Power (1853-1927), an American Chemist who in 1896 became the Chief Scientist at Wellcome Chemical Research laboratories in London. During his career he examined the constituents of plant-based medications including investigating Chaulmoogra oil, which was noted for its use in traditional Indian medicine as a treatment for leprosy.
