Zeta can be used to calculate zeta potentials for ka>6 from electrophoretic mobilities measured at the stationary level, from apparent zeta potentials displayed by zetameter or from apparent mobilities measured at 3 different levels in a rectangular cell.

Colloidal Dynamics offer laboratory and online instrumentation for direct measurement of particle size and zeta potential in concentrated colloids.
