Zeta potential : +/-200mV Particle size : 1nm - 100µm Resolution : 0,1mV (in water) The WALLIS Wallis an instrument dedicated to Zeta potential WALLIS is an innovative zeta potential analyzer dedicated to the characterization of nanoparticle suspensions. It is based on a revisited and modern version of the Laser Doppler Electrophoresis (LDE) technique oering a unique and unequaled measurement resolution. It is complementary to the Cordouan’s VASCO particle size analyzer to study colloidal solution stability and properties. Particle with negative surface charge Surface potential Zeta...

WALLIS^ technology led to its best Think « out of the box » for high resolution measurement
