Definition that contains semipermeable membrane
- dialysis separation of substances in solution by means of their unequal diffusion through semipermeable membranes
- osmosis (biology, chemistry) diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
- osmotic pressure (physical chemistry) the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane
- reverse osmosis (chemistry) a method of producing pure water; a solvent passes through a semipermeable membrane in a direction opposite to that for natural osmosis when it is subjected to a hydrostatic pressure greater than the osmotic pressure
- dialyzer a medical instrument for separating substances in solution by unequal diffusion through semipermeable membranes
- pervaporate cause (a liquid) to evaporate through a semipermeable membrane
- pervaporate evaporate through a semipermeable membrane
- dialysis machine a medical instrument for separating substances in solution by unequal diffusion through semipermeable membranes
- pervaporation the concentration of a colloidal solution whose colloid will not pass through a semipermeable membrane; solution is placed in a bag of the membrane and the solvent is evaporated off
