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 The device is no longer used in practice, having been replaced by osmometers of different designs.
The analysis highlights Measurement, Construction and operation and Significance as prominent areas in the source structure around Pfeffer cell.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
