The Malvern Zetasizer Nano ZS (ZEN3600) is a high-performance benchtop analyzer that measures particle size, zeta potential, molecular weight, and mobility using Dynamic Light Scattering (DLS), Electrophoretic Light Scattering (ELS), and Static Light Scattering (SLS). Featuring patented Non-Invasive Back-Scatter (NIBS®) and M3-PALS® technologies, it delivers accurate results even in high-concentration or high-conductivity samples. This 2015 unit (S/N MAL1111230) was lightly used in a biotech lab and remains in good cosmetic and functional condition. Currently idle but powers on and passes self-diagnostics. Ideal for nanoparticle characterization, protein aggregation studies, and formulation development.
Key Features:
- NIBS® optics for high-concentration size measurement
- M3-PALS for accurate zeta potential in conductive media
- 173° backscatter + 13° forward scatter
- Optional flow-mode for SEC/FFF integration
- SOP-driven software with Expert Advice™ quality checks
- Supports MPT-2 autotitrator (not included)
