Zetasizer - Automated Protein Size Measurement

The world’s most widely-used automated protein size measurement systems for nanoparticle, colloid and biomolecular particle sizing and particle charge measurements.

Instruments in the Zetasizer family are used to measure the particle size of dispersed systems from sub-nanometer to several micrometers in diameter, using the technique of Dynamic Light Scattering (DLS particle size analyzer). Zetasizer systems are also used as particle mobility analyzer and charge (Zeta potential) using the technique of Electrophoretic Light Scattering (ELS), and the molecular weight of particles in solution using Static Light Scattering (SLS).

The Zetasizer is available as the Zetasizer Advance range of laboratory benchtop systems (successor to the popular Nano range), and as the Zetasizer WT and AT Process systems.

Zetasizer Advance is the successor to the highly successful and market-leading Zetasizer Nano.

Each of the three models in the Zetasizer Advance Range offers particle size, particle charge analyzer (zeta potential) and molecular weight analysis. In addition, each benefits from advances including Adaptive Correlation, M3-PALS zeta potential analysis, constant current zeta mode and our deep learning-based data quality advice system.

Each of the three models is available as a Blue Label or Red Label variant:

• Choose Blue Label for routine sample investigation such as metallic colloids, metal oxides and pigments
• Choose Red Label for more challenging sample types, such as proteins, surfactant solutions and low solid content samples

All Zetasizer Advance systems offer on-site upgradeability with minimal downtime. Should your needs change, your Zetasizer can adapt to new challenges.
