Particle Size Analyzer - Zetasizer Nano S90

Malvern Panalytical offers a low-cost particle size analyzer called Zetasizer Nano S90. This entry level system is perfect for applications where similar results to a legacy system with 90 degree scattering optics are needed.

The Zetasizer Nano S90 can be used for measuring molecular weight using static light scattering and for measuring molecular and particle size at a 90 degree scattering angle using dynamic light scattering. The system can be used in those applications where the ultimate in sizing sensitivity is not required.

Key Features

The main features of the Zetasizer Nano S90 are:

  • Molecular weight measurement down to 9,800 Da.
  • Size measurement from 0.3 nm (diameter) to 5 µm using 90 degree scattering optics
  • Alternative laser, 50 mW at 532 nm for samples incompatible with the traditional 633nm laser fitted
  • Autotitrator option allows automation of measurements
  • Optical filter option to enhance measurements with fluorescent sample
  • Research software option provides to more features and analysis algorithms for the light scattering specialist
  • 21CFR part 11 software option allows compliance with ER/ES
  • Temperature range extension option to 120°C
  • Systems can be upgraded to include zeta potential

Customer Testimonial

My students have always had great things to say about the Zetasizer Nano. They say it’s very easy to use. The software is very user-friendly and it can accommodate particles of various different sizes, so I have never had reason to evaluate another particle sizing instrument.

What I really like is the ability to look at different size colloids. I will be using the two new instruments with my junior level class in biomedical engineering and materials science. These students will be using the Zetasizer Nano systems to try to figure out which type of colloid is most useful to put onto surfaces for antimicrobial properties.

Our more senior researchers in the Department of Materials Science and Engineering use the Zetasizer Nano to monitor and analyze how particles change or degrade during our experiments. It is important for us to successfully make batches of particles that are consistently below 10 nanometres. The Zetasizer Nano allows us to get quantitative information on the diameter of particles we’re going to utilize for subsequent experiments.
