Excellent instrument for water treatment optimization - great support from Malvern!
Rating: 4.3

  • Application Area: Water Treatment

"Excellent product which we believe has massive potential. The product is relatively easy to use - we have found variable results under certain conditions and are performing research to optimize the measurement for our samples. After a slow start we had really excellent support from Malvern which included a site visit to discuss erroneous readings (Mike Kasuba and Kerry) - this support was hugely appreciated and has given us a springboard for starting the research in earnest. We feel that zeta potential has the potential to become THE method for coagulant dosing control on water treatment works. Whilst our research is ongoing the results to date suggest that the measurement may allow us to be optimized more of the time (providing more robust water treatment processes) whilst potentially saving large amounts of money by reducing chemical dosing."

Good addition to the R&D capabilities
Rating: 3.3

  • Application Area:Measure particles size of emulsion polymers

"Easy to use. Results vs. other equipments are similar when unimodal particle size distribution are measured. Low reproducibility when bi- or tri-modal systems are analyzed. It might be just a matter of dermining the right method"

Manufacturer's Response

Thanks for your comments Luis, You have put that you own a Nano Z, but I assume it’s a Nano S or ZS as you state that you measure particle size. Dynamic Light Scattering is deemed a relatively low resolution technique and as such you may experience more variable results with bi-modal or tri-modal samples and you may not resolve the individual modes if they are closer than 3:1 ratio of sizes. For your multimodal samples you may want to manually increase the measurement time. If you have concerns then please send these along with data illustrating the problem and I am sure we can advise on how to improve reproducibility.

Reproducible results, easy to use.
Rating: 4.0

  • Application Area:Sizing nanoparticles

"The Zetasizer is very easy to use. The only hiccup we've had is in knowing the default applied voltage and how to change that if need be."

Zetasizer Nano Z for zeta potential measurements - Dedicated zeta potential analyzer.

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.


Zetasizer Nano Z Features:

  • 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.
