Zetasizer Nano Series

The new Zetasizer Nano series allows the measurement of the three most important parameters in colloids and polymers: particle size, zeta potential, and molecular weight.
These instruments incorporate advanced technology, offering excellent sensitivity and diverse features. Malvern’s patented NIBS light technology is applied to the Nano Z and Nano ZS, enabling sample measurement without dilution or with slight dilution. The Zetasizer Nano ZS is the best instrument in the Malvern Zetasizer Nano series, capable of measuring all three parameters without performance adjustment.

The Nano ZS, Z, ZS90 instruments all use Malvern Instrument’s unique disposable zeta potential cells to prevent sample contamination.

     * Particle size – The NIBS technique allows the measurement of particle and molecular sizes between a maximum size range of 0.3nm and 10µm.

     * Zeta potential – The M3-PALS technique accurately measures the zeta potential of samples in both aqueous and non-aqueous dispersants.

                       
     * Molecular weight – Provides the sensitivity and stability required for absolute molecular weight measurement by using Avalanche Photodiode detectors and optical transmission equipment.
