Abstract
Micro and multipurpose analytical tools are in high demand for procuring physicochemical data. Thereby conductance and specific conductance (κ), surface tension (γ) and viscosity (η) of 0.066 to 0.333 mol/kg urea and methylurea, the osmotic pressure (π) for 0.1 to 1.0 mol/kg sucrose with 0.01 mmol/kg aqueous KCl solutions simultaneously were studied with oscosurvismeter. The solutions of different compositions were taken in cells, partitioned by nitrocellulose semipermeable membrane (SPM) for osmotic pressure. Survismeter, osmometer, electrodes, metallic clamp, SPM and high potential metallic springs are key parts of the oscosurvismeter. The conductance data were in close agreement with those of Horiba Conductivity Meter DS-8 M, surface tension data with that of face automatic surface tensiometer, CBVP-Z, Kyowa Interface Science Co. Ltd., viscosity data with survismeter, Spectro Analytical Pvt Ltd. The conductance and viscosities for methylurea are higher than those of the urea with comparatively stronger hydrophobic interaction of the -CH3 group of the methylurea. Statistical analysis of cost involved with oscosurvismeter was 99% less as compared with individual methods.
