The Zetasizer Nano Z system is dedicated to the measurement of zeta potential and electrophoretic mobility in aqueous and non-aqueous dispersions using Laser Doppler Micro-Electrophoresis. The Zetasizer Nano Z is the perfect system for measuring zeta potential and electrophoretic mobility of colloids and nanoparticles, when the measurement of size or molecular weight is not required. Zeta potential using patented M3-PALS technology. A Quality Factor and Expert Advice System gives the confidence of having an expert at your shoulder. 21CFR part 11 software option to enable compliance with ER/ES. Research software option to give access to further features and analysis algorithms for the light scattering specialist. Automation of measurements using an autotitrator option. Alternative laser, 50mW at 532nm for samples incompatible with the standard 633nm laser. Optical filter option to improve measurements with fluorescent sample. Temperature range extension option to 120°C.
