The ESA-9800

Using a patented method called Electrokinetic Sonic Amplitude, the ESA-9800 System achieves remarkable electrokinetic measurement results while eliminating the severe limitations and restrictions of the traditional microelectrophoresis technique. With ESA, particle mobility and Zeta Potential can be measured simultaneously with pH, conductivity, and temperature. Samples can even be titrated during the measurement.

The ESA-9800 enables you to measure aqueous and non-aqueous dispersions in the concentration range of 0.5% to over 40% by volume of the dispersed phase. Systems of particles up to 50 microns in size can be measured without difficulty. Samples can even be vigorously stirred or mixed so particle settling is never a problem. No optical alignment is required. The high frequency electric field is only applied in extremely short pulses, so there is never any worry about the sample being affected by the measurement.

In short, you can take real measurements on real samples
