ZPA 20

The Zeta Potential Analyzer ZPA 20 utilises the patented bidirectional oscillating streaming potential method for the measurement of zeta potential of various materials with a high degree of accuracy and precision. Samples with plate shaped geometries, fibres and powders can be easily prepared and measured as well. High precision measuring probes for voltage, current, conductivity, pH value, pressure and temperature are also possible with the system.

  • Based on patented bidirectional oscillating streaming potential approach 
  • Oscillation frequencies of up to 0.5 Hz with use of high performance stepper-motor device 
  • Measuring probes for current, voltage, pressure, conductivity, pH value and temperature are possible
  • Fast measurement time typically under 1 min for a single zeta potential test
  • For automated different pH measurements, optional liquid dosing unit can be added on
  • Different measuring cells for powders, fibres, plate shaped solid samples & granulate materials available for diverse sample types
