Pfeffer cell

Pfeffer cell (German: Pfeffersche Zelle) is a membrane osmometer developed by the German botanist Wilhelm Pfeffer to measure the osmotic pressure of aqueous solutions. Pfeffer described the design in his 1877 publication Osmotische Untersuchungen. The device is no longer used in practice, having been replaced by osmometers of different designs.
