Application:

SurSurPASS is an electrokinetic analyser used to determine the zeta potential (z [mV]) of macroscopic solid surfaces on the basis of the streaming potential principle. It has the ability to work with different cells for the measurement of the potential of materials (granules, fibres, yarns, fabrics and other solid surfaces). Additionally, it is possible to monitor the adsorption of polyelectrolytes/ surfactants to the solid surface in relation to the change od zeta potential.


Technical characteristics:

  • Streaming potential: -2000 mV … +2000 mV
  • Streaming current: -200 μA … +200 μA
  • Cell resistance: 5 Ω … 20 MΩ
  • Differential pressure: -1000 mbar … +1000 mbar
  • Volume flow rate: 10-300 mL/min
