The world’s most widely used particle analyzer!
The Zetasizer Nano ZS is a high performance two angle, particle size, zeta potential and molecular weight analyzer. Ideal for the measurement of small volume samples, samples at very low or high concentration and the detection of aggregates. Using Non-Invasive Backscatter optics (NIBS) it has significantly better performance than systems using 90 degree scattering optics.
