    • Osmotic potential was determined on the same leaf with a vapour pressure osmometer, after samples were frozen and thawed.
    • The value of the solution dripping out of the segments was measured periodically with the osmometer.
    • The concentration of the samples exceeded the capacity of the osmometer and therefore were diluted with distilled water (1: 1 or 1: 2 urine: water depending on concentration of sample) prior to the measurement.

Derivatives

  • osmometric

  • adjective
    • The osmometric measurement of molecular weight is based on the fact that the osmotic pressure is proportional to the number of gram-molecules of dissolved material in a definite volume of solution.
  • osmometrically

  • adverb
  • osmometry

  • noun
    • Additionally, sedimentation equilibrium, osmometry, neutron, and x-ray scattering, and self-interaction chromatography have been employed to quantify protein solution nonideality.
      Example sentencesExamples
      • During the past 5 years the pressure-probe technique and picolitre osmometry have been used to study the biophysical limitation of cell expansion in cereal leaves.
      • Other methods of molecular weight determination include gel permeation chromatography, end-group analysis, and osmometry.
      • Osmotic potentials of xylem sap and the external medium were estimated by freezing point depression osmometry.
      • Osmolality was measured by vapor pressure osmometry.
