Malvern Panalytical Zetasizer Advance Series - Ultra (Red) ZSU3305

Zetasizer Advance Series - Ultra (Red) ZSU3305 is a bench-top light scattering system for measurement of particle and molecular size, particle charge (zeta potential) and particle concentration. The instrument uses Dynamic Light Scattering (DLS), Multi-Angle Dynamic Light Scattering (MADLS) and Electrophoretic Light Scattering (ELS) with M3‑PALS and constant-current zeta modes to characterise nanoparticles, colloids and macromolecules. The Red Label Ultra model adds particle concentration capability and is supplied with ZS Xplorer software for guided acquisition, analysis and data-quality feedback.

Key Features:

• Model: ZSU3305 (Zetasizer Ultra, Red Label)
• Measurement techniques: DLS, MADLS and ELS with M3‑PALS and constant‑current zeta mode
• Particle size measurement range: 0.3 nm to 10 µm
• Particle concentration measurement capability (Red Label only)
• Supports low-volume disposable capillary sizing cell for sample volumes from 3 µL
• Includes ZS Xplorer software with data quality advice and analysis tools

Advantages:

• Most advanced Zetasizer platform for deeper sample insight through MADLS and concentration measurements
• High data confidence and user guidance via ZS Xplorer’s data‑quality advice system
• Accurate zeta-potential analysis using M3‑PALS and constant‑current zeta modes for challenging samples
• Low-volume measurement capability (from 3 µL) reduces sample consumption for precious or scarce samples
• Sample throughput and workflow efficiency improved through optional Sample Assistant and automated accessories
