Dataphysics DCAT 11 Dynamic Contact Angle Meter and Tensiometer
WebMay 13, 2009 · Aqueous solution equilibrium surface tension values were obtained by the Wilhelmy plate method using a Dataphysics tensiometer, model DCAT11. The CMC value was taken at the intersection of the linear portions of the plots of the surface tension against the logarithm of the surfactant concentration. Surfactant solutions were prepared with ... WebA Wilhelmy plate (DCAT11, dataphysics, Filderstadt, Germany) was used to measure the interfacial tension. It was determined to 17 mN/m for the low viscosity oil, to 20 mN/m for the medium viscosity oil and to 18 mN/m for the high viscosity oil after a measuring time of 2 h at a temperature of 20 °C. dagleh group pty ltd
