  "term": "Osmometer",
  "field": "Chemistry",
  "definition": "An instrument designed to measure the osmotic pressure of a solution, typically used to determine the number-average molar mass of polymers. It operates by separating a polymer solution from a pure solvent with a semipermeable membrane, measuring the pressure difference required to prevent solvent flow. Common types include membrane osmometers and vapor pressure osmometers.",
