Title of Invention

AN INSTRUMENT FOR DETERMINING OSMOTIC PRESSURE, CONDUCTANCE, VISCOSITY AND SURFACE TENSION OF LIQUID SOLUTION

Abstract Oscosurvismeter is made of Borosil glass material for measuring osmotic pressure (n), specific conductance (K), viscosity (q) and surface tension (y) of solutions. Solutions of different strengths are taken in two cells/compartments, partitioned by semi permeable membrane (SPM), respectively. Concentration gradient makes the solvent move towards concentrated solution to establish equilibrium this measures osmotic pressure (TI). The Oscosurvismeter saves time and material, and enhances accuracy and precision in measurements, the instrument consists six parts (1) Survismeter (2) Osmometer (3) Electrode (4) Metallic clamp (5) Semipermeable membrane (SPM) (6) High potential metallic springs. The high accuracies data are noted with the instrument.
