Zetasizer Lab
BY
Malvern Panalytical
Description
Our entry-level Zetasizer does not compromise on features. The Zetasizer Lab incorporates Adaptive Correlation, M3-PALS and constant current zeta mode. The Zetasizer Lab also ships with ZS Xplorer, easy-to-use analytical software. ZS Xplorer offers instant feedback on data quality, and guidance on how to improve your results.
Key Differences
The Zetasizer Lab is the perfect entry-level system, offering a wide range of features, including:
DLS analysis: particle size measurements from 0.3 nm to 10 μm
Extended size range analysis offers improved accuracy for particle sizes above 1 μm, and indicative results above 10 μm (using ZSU1002 Low Volume Disposable Sizing Cell)
Zeta potential of nanoparticles and colloids using M3-PALS analysis and constant current zeta mode
Molecular weight using Static Light Scattering at 90°
Supports use of Low Volume Disposable Capillary Cell for size measurements in sample volumes as low as 3 μL
Available in Blue Label and Red Label variants:Choose Blue Label for routine sample investigation such as metallic colloids, metal oxides and pigments
Choose Red Label for more challenging sample types, such as proteins, surfactant solutions and low solid content samples
On-site upgradeability to either Zetasizer Pro or Zetasizer Ultra models
