IntroductionThe ODBA-1M is an advanced measurement module for the PAT-1M. By combining direct capillary pressure measurement with controlled oscillations of pendant drops and buoyant bubbles, the module enables precise characterization of dynamic interfacial rheological properties.
Measurement principleThe module applies controlled oscillatory deformation to pendant drops or rising bubbles while recording capillary pressure and optical geometry in real time. Analysis of the synchronized signals yields interfacial viscoelastic parameters (elastic and viscous moduli) and surface tension dynamics.
