The Malvern Zetasizer series measures particle and molecule size from below a nanometer to several microns using dynamic light scattering, zeta potential and electrophoretic mobility using electrophoretic light scattering, and molecular weight using static light scattering. In addition the system can be connected to a GPC / SEC system to use as a chromatography detector. The system is available in a range of variants that allows you to select the best system for your application and budget, and the philosophy of the design is to ensure exceptional ease of use and give confidence in the results without compromising performance.

This note discusses how DLS-based optical microrheology can be used to determine the rheological behavior of polymer solutions and the impact of tracer particle chemistry on the measured microrheological response.

This presentation discusses the importance of particle size, zeta potential and rheology for a functional suspension, and demonstrates how these properties can be manipulated to induce dispersion stability.
Zeta potential or particle charge is the driving force responsible for the stability and flocculation of particles in a water treatment plant. Neutralization of this charge by oppositely charged coagulants is key for formation of stable, easily filte...
The stability of a protein sample and its tendency to aggregate is explored using a combination of SEC-MALS and DLS
Stability and particle size define material and biomaterial performance and the Zetasizer Nano is perfectly placed to deliver this information within our multi-user environment. The instrument is robust, easy to use and data acquisition is straightforward. It is as close to ‘student proof’ as it is possible to be!
