Advance with Confidence

The new Zetasizer Ultra is our most advanced system for the measurement of particle and molecular size, particle charge and particle concentration, and represents the most intelligent and flexible instrument in the Zetasizer range. 

This flagship instrument enjoys all the benefits afforded by ZS Xplorer software, in terms of ease of use, analysis speed and data confidence, and also offers two unique measurement capabilities: Multi-Angle Dynamic Light Scattering (MADLS®) and Particle Concentration, to offer even greater insight into your samples.

Advanced

The Zetasizer Ultra is the ultimate companion for fast yet accurate particle and molecule sizing, particle charge and particle concentration measurements, and represents the most intelligent and flexible instrument in the Zetasizer range.
This powerful system has the unique capacity to perform calibration-free particle concentration measurements with ease, even deep into the nano size range.

Assured

Alongside Malvern Panalytical’s NIBS (Non-Invasive Back-Scatter) technology, the Zetasizer Ultra offers Multi-Angle Dynamic Light Scattering (MADLS®). This ground-breaking technique provides high resolution angle-independent size measurements, meaning no more worry about missing particles in your sample. With MADLS, you can be sure that all angles are simultaneously covered.

Expert

Pushing the upper analytical size range higher than ever before, the Zetasizer Ultra is designed to provide data you can trust to help you make those important decisions to improve your products and processes. Despite its unique capabilities, the Zetasizer Ultra’s speed and ease-of-use are uncompromised, making it by far the most advanced and powerful light scattering system available.

Key features

  • Multi-Angle Dynamic Light Scattering (MADLS) for high resolution angle-independent size measurements offers greater insight into the size distribution of your sample
  • Disposable capillary sizing cell provides the ultimate in non-destructive, low volume (down to 3 μL) analysis, with an upper size range that extends to 10 μm
  • Simple, calibration-free measurement of particle concentration in homogeneous sample types, covering a wide range of materials
  • Electrophoretic Light Scattering (ELS) measures the zeta potential of particles and molecules, indicating sample stability and/or propensity to aggregate
  • Sample-centric ZS Xplorer software enables flexible, guided use, and the capability to build complex methods with ease
  • Optical filter wheel offers a fluorescence filter and both vertical and horizontal polarizers for analytical flexibility
  • NIBS (Non-Invasive Back-Scatter) technology maximizes the dynamic range, providing the highest sensitivity for even the most concentrated samples
  • The deep-learning empowered Data Quality System assists users in understanding which of their size data might be poor, and why. This intelligent neural network system also suggests how to improve results, helping even less-experienced users generate excellent quality data
  • Adaptive Correlation produces reliable and repeatable data over twice as quickly, providing a truly representative view of the sample
  • M3-PALS with Constant Current Mode measures electrophoretic mobility and zeta potential in high conductivity media
