The Malvern Panalytical Zetasizer Ultra (Red Label) is an advanced light scattering system designed for comprehensive characterization of particle and molecular size, zeta potential, and particle concentration. Engineered to analyze a wide variety of materials, including challenging samples such as viruses and virus-like particles (VLPs), the instrument delivers highly accurate measurements with minimal or no sample dilution. By integrating Non-Invasive Back Scatter (NIBS) and Multi-Angle Dynamic Light Scattering (MADLS®) technologies, the system provides enhanced particle size characterization over a broad size range while supporting low sample concentrations and sample volumes as small as 3 μL. Its combination of high sensitivity, measurement flexibility, and advanced analytical capability makes the Zetasizer Ultra an excellent solution for research, formulation development, and quality control laboratories.
