How It Is Used
Two liquids that do not mix are poured in and left to settle into layers by density. Opening the stopcock drains the lower layer, and it is closed when the boundary reaches the outlet, leaving the upper layer behind. This laboratory separating funnel is used in organic chemistry, forensic and environmental work for extraction and purification.
