Zeta Potential Measurement

Surface charge (Zeta-Potential) of particles via Zetasizer Nano ZSP

Zeta potential is a measure of the magnitude of the electrostatic or charge repulsion/attraction between particles and is one of the fundamental parameters known to affect colloidal stability. Its measurement brings detailed insight into the causes of dispersion, aggregation or flocculation, and can be applied to improve the formulation of dispersions, emulsions and suspensions.

Sample Measurements

  • Particle sizes between 5 nm – 10 μm
  • Determination of Zeta-Potential
  • pH Titration of Zetapotential
  • Determination of Isoelectric Points

Sample Requirements

  • Aqueous suspension or dried particles
  • Slow particle sedimentation (size below 10 μm)
  • 0.1 % Solution, minimum amount 1 mg


  • < 10 samples: 120 € / sample
  • ≥ 10 samples: 110 € /sample
