High performance, versatile and robust

The new Zetasizer Pro is your go-to instrument to measure a wide range of sample types and concentrations. It offers wide dynamic concentration capability and high sensitivity due to the Non-Invasive Back Scatter (NIBS) optical design.


Even novice users will produce the highest-quality measurements using the Zetasizer Pro, which benefits from:

  • Dynamic Light Scattering (DLS), which measures particle and molecule size, from 0.3 nm to 10 µm  
  • Electrophoretic Light Scattering (ELS), which measures the zeta potential of particles and molecules, indicating sample stability and/or propensity to aggregate  
  • Non-Invasive Back Scatter (NIBS), optics for versatile, high sensitivity, particle and molecular size measurements and molecular weight measurements  
  • M3-PALS with Constant Current Mode, for zeta potential and electrophoretic mobility measurements  
  • ZS Xplorer software suite, for simple and flexible method set-up and data analysis  
  • Adaptive Correlation, for faster, more reproducible sizing measurements with less sample preparation  
  • Deep learning-based data quality system, for assessment of any size data quality issues, with clear advice on how to improve results  
  • Optical filter wheel with fluorescence filter, to allow measurement of fluorescent samples without impairing overall system sensitivity.  Also includes polarization filters for DDLS measurements
