Malvern Zetasizer S and Z

Zetasizer nano
Nanoparticle Size and Zetapotential

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.

The Zetasizer Nano S is for measuring nanoparticles in the range of 3 nm up to 3µm


  • Zeta potential using patented M3-PALS technology.
  • A ‘Quality Factor’ and ‘Expert Advice System’ gives the confidence of having an expert at your shoulder.
  • A standard 633nm laser..
  • Temperature range to 50°C
