A membrane osmometer is a scientific instrument used to measure osmotic pressure, which is the pressure required to stop the flow of solvent across a semipermeable membrane due to osmosis. Osmosis is the movement of solvent molecules (usually water) from a region of lower solute concentration to a region of higher solute concentration through a semipermeable membrane.
