osmometer
measurement instrument
Quick Summary
An osmometer is an apparatus used to measure osmotic pressure. Osmotic pressure is the force required to prevent the movement of a solvent across a semipermeable membrane from a less concentrated solution to a more concentrated one. This phenomenon, known as osmosis, is crucial in biological systems for regulating water uptake in plants and maintaining cell size. It also has industrial applications, such as in desalination. The term "osmometer" was first used in 1854.12
