Matec ESA-8000 Electroacoustic zeta-potential meter
| Located: |
| In the teching lab 323 |
| Principle: |
| Electrokinetic Sonic Analyzator
Principle: A high-frequency electric field is applied on the dispersion. The particles move electrophoretically in the applied field. If the particles' density differs from that of the liquid, the motion generates an alternating acoustic wave. |
| Specifications: |
| Concentration range: 0.5% to 40% vol. (according to manufacturer)
Particle size: up to 50 µm
Volume: Minimum 30 ml, no maximum specified.
Titration: Samples can also be titrated during the measurement. |
| Operation: |
| Applications: For aqueous and non aqueous dispersions.
Measures particle mobility, zeta potential, pH, conductivity and temperature.
Non destructive method. Stirring the dispersion does not affect the measurement. |
| Maintenance: |
| Authorized personell only |
