The Nanoparticle Size and Zeta Potential Analyzer Zetasizer Pro provides two light scattering techniques: Dynamic Light Scattering (DLS) and Electrophoretic Light Scattering (ELS). By measuring the frequency and intensity of scattered light, it can determine the size and charge of materials. This information is often used to shorten the development time of colloid (including protein) and emulsion formulations and to enhance their stability, as well as to assess the level of aggregation in the system. The core functions of the device include particle size analysis, zeta potential measurement, and molecular weight determination.

The device is widely used for:

1. Conducting nanoparticle size distribution and stability analysis.

2. Drug development: Evaluating the size and zeta potential of nanocarriers in drug delivery systems.

3. Analyzing the size and charge characteristics of proteins and other biomolecules to optimize formulations and improve stability.

4. Evaluating the properties of colloidal particles and suspensions.

5. Studying the size distribution and stability of emulsions, suspensions, and polymer solutions to optimize processes and product performance.
