"An osmometer is a device for measuring the osmotic strength of a solution, colloid, or compound. There are several different techniques employed in osmometry: • Vapor pressure osmometers determine the concentration of osmotically active particles that reduce the vapor pressure of a solution. • Membrane osmometers measure the osmotic pressure of a solution separated from pure solvent by a semipermeable membrane.
