Description

High-Resolution Zeta Potential Analysis : 0,1 mV

 

Definition of Zeta potential
 

Particles in solution are surrounded by an Electrical Double Layer (EDL) that characterizes particle-particle interaction. It fully determines the formulation stability. The measurement of Zeta potential is directly related to particle charge environment and then inform about dispersion stability. It is widely use for chemical synthesis, particle functionalization…etc.

 

cordouan wallis cell

Measurement cell

independent electrodes coupling to a standard dip cell

Simple

The dip cell design allows simple and easy sample preparation and prevents bubble formation. It is compliant with standard cuvette and available in different materials: polystyrene, glass or quartz fully compatible with organic solvent.

Robust

The innovative vitreous carbon electrode provides long life, oxidation free electrodes that can be easily cleaned by standard process like ultrasonic bath or acid-base washing. Artefact free

Artifact free

WALLIS optimized dip cell electrodes design prevents from artifact like electro-osmosis effects by suppressing solvent induced displacement along the wall of the cuvette; No software correction is needed to the measured signal

 

WALLIS Key Benefits
 

- Accurate value of zeta potential to predict and monitor dispersion stability

- Useful for formulation work
