The Zetasizer Nano ZS90 is the perfect lower cost solution when the ultimate in sizing sensitivity is not necessary, or where identical results to a legacy system with 90 degree scattering optics is required.

  • Size measurement from 0.3nm (diameter) to 5 microns using 90 degree scattering optics.
  • Zeta potential of colloids and nanoparticles using patented M3-PALS technology.
  • Molecular weight measurement down to 9,800Da.
  • A ‘Quality Factor’ and ‘Expert Advice System’ gives the confidence of having an expert at your shoulder.
  • 21CFR part 11 software option enables compliance with ER/ES.
  • Research software option gives 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 fitted.
  • Optical filter option to improve measurements with fluorescent sample.
  • Temperature range extension option to 120°C.
