Products > Analytical > Zeta potential > ELSZ-2000Z
ELSZ-2000Z measures the surface potential of solid samples and concentrated samples. With the electro-osmosis measurement, the zeta potential of solid samples and micro-volume(130μl or more) samples can be precisely analyzed.
If you would like to additionally check the particle size with a single device, please check our ELSZ-2000ZS model.
