Description

Malvern Instruments Zetasizer Nano-ZS ZEN3600 Particle Sizer Lab

The Malvern Instruments Zetasizer Nano ZS, ZEN3600 provides dynamic light scattering  (DLS) for the measurement of the size of colloids, nanoparticles and molecules, without requiring agitation to make the sample suitable for analysis. From the size, an estimate of the molecular weight can be made, which has the benefit of being faster to confirm oligomeric state than size exclusion chromatography.

Features:

• Little or no dilution required to simplify sample preparation
• Wide range of sample suitability from nanoparticles to emulsions and macromolecules
• MPT-2 Autotitrator to automate pH and ionic concentration trends, improving productivity
• Elimination of cross-contamination using disposable cells to improve accuracy
• Data assessment using quality report and ‘Expert advice’ system
• Can be used as a chromatography detector for on-line size measurement.
• NIBS optics ensures exceptional performance
• Automation of temperature trends
