Malvern Panalytical Zetasizer Advance Series - Lab (Red) ZSU3105

Zetasizer Advance Series - Lab (Red) ZSU3105 is a laboratory benchtop light scattering instrument for measurement of particle size, zeta potential and molecular weight in dispersed systems. The Zetasizer Lab (Red label) performs dynamic light scattering (DLS) size measurements (90° side-scatter), electrophoretic light scattering (M3-PALS and constant current zeta mode) for particle charge, and static light scattering for molecular weight, and is supplied with ZS Xplorer analytical software for data acquisition and quality feedback. The instrument supports low-volume measurements using the ZSU1002 capillary sizing cell and is intended for challenging sample types such as proteins, surfactant solutions and low solid content samples.

Key Features:

• Model: ZSU3105 (Zetasizer Advance Series, Lab, Red label)
• Particle size (DLS) range: 0.3 nm to 10 μm
• Zeta potential: M3-PALS analysis and constant current zeta mode
• Low-volume capability: compatible with ZSU1002 low volume disposable capillary cell (sample volumes from 3 μL)
• Includes ZS Xplorer analytical software with instant data-quality feedback

Advantages:

• Enhanced measurement reliability via Adaptive Correlation and M3-PALS zeta analysis
• Ability to analyse challenging, low-concentration or protein-containing samples using the Red label configuration
• Low-volume sampling reduces sample consumption (down to ~3 μL) for precious or limited samples
• Integrated user guidance from ZS Xplorer improves data quality assessment and workflow efficiency
