Malvern Panalytical offers the Zetasizer Nano Z system, which is exclusively designed for measuring electrophoretic mobility and zeta potential of nanoparticles and colloids through Laser Doppler Micro-Electrophoresis. The system is suitable for those applications where measurements of molecular weight or size are not needed.

The Zetasizer Nano Z system comes with a wide range of reusable and disposable cells to improve the measurement in terms of flow measurement, sample volume and concentration. Accessories include MPT-2 Autotitrator and SV-10 viscometer.

Key Features

The main features of the Zetasizer Nano Z system are:

  • Zeta potential using patented M3-PALS technology
  • Research software option provides access to additional features and analysis algorithms for the light scattering specialist
  • 21CFR part 11 software option allows compliance with ER/ES
  • Autotitrator option allows automation of measurements
  • Temperature range extension option to 120°C
  • Optical filter option to enhance measurements with fluorescent sample
  • Alternative laser, 50 mW at 532 nm for samples incompatible with conventional 633 nm laser

Customer Testimonial

The Zetasizer Nano is so easy to use. All my students can familiarise themselves with it very quickly. As a result, we are purchasing a second instrument to ensure we have enough capacity for our expanding research programme in this area. // We are making block copolymer nanolatexes directly in water using a very versatile and efficient aqueous dispersion polymerisation formulation. By targeting an appropriate block composition, we can prepare spherical nanoparticles of pre-determined diameter within the technologically important 25 to 100 nm size range at relatively high particle concentrations. Recently, we have extended our formulation to prepare worm-like polymer particles and hollow particles known as vesicles.
