Price of Nano Particle Potential Analyzer

Zeta potential meter is a fundamental property of colloidal suspensions. Basically, it is closely related to the number of charges attached to the surface of particles immersed in the solvent. Therefore, it is associated with particle particle interactions and formulation stability in a very complex way described by physical models such as electric double layer (EDL).
