Definition of osmometer in English: osmometernoun ɒzˈmɒmɪtəɑzˈmɑmədər An instrument for demonstrating or measuring osmotic pressure. Example sentencesExamples - Individual cell osmotic pressure is measured using a picolitre osmometer.
- To obtain a direct measurement of the osmolality, 50 randomly selected samples were analyzed with an osmometer.
- 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 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.
adverb 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.
