The concept of zeta potential was recognized more than 100 years ago, but early instruments were fragile and custom-made. About 50 years ago, we pioneered the development of a simple, reliable instrument to measure electrophoretic mobility and zeta potential. Our Zeta-Meter 4.0 continues this tradition but with improvements that make the determination even more convenient.

Our instruments are reasonably priced and feature low maintenance costs. In addition, careful quality control has enabled us to maintain an excellent reliability record. If your problem involves electrokinetics, then we probably know something about it. If we don't make exactly what you need, then we will recommend a reliable company that does.
