The Malvern Zetasizer range provides both exceptionally high performance and entry level systems that incorporate combinations of a particle size analyzer, zeta potential analyzer, molecular weight analyzer, protein mobility and microrheology measurements. Particles and molecules from less than a nanometer in size to several microns can be analyzed by a range of variants to suit your applications and budget.
The systems measure size and microrheology using dynamic light scattering, zeta potential and electrophoretic mobility using electrophoretic light scattering, and molecular weight using static light scattering. In addition the system can be used in a flow configuration to connect to a GPC / SEC system for use as a chromatography size detector.

Many large scale industrial processes (paper production, water treatment and dewatering processes) require de-stabilization or flocculation of dispersed particulates. For other industries and products such as foods, cosmetics, paints and pharmaceutic...
Significant advances have been made in analytical technology for the characterization and identification of particles present in pharmaceutical products. With these advances comes a tremendous amount of new data with which to characterize biologics, ...
Cosmetics, paints, inks, paper, drug delivery, personal care, food or intra-lipid emulsions are made up of multi component chemistries. Most products go through a stage where different phases co-exist such as emulsions, suspensions or dispersions and...
Correctly targeting a drug product’s delivery location and defining its release profile are critical challenges and the subject of a great deal of research. The role of polymers in drug delivery applications is growing, with particular emphasis on ta...
Particle size analysis is important in many industries. Knowledge of particle size is important in the food industry because it affects the production and handling of ingredients and the formulation, processing, and quality control of food and bevera...
Controlling the dispersion or flocculation of colloidal suspensions through zeta potential
(October 20 2016)
Nanoparticle size is an important criterion for our formulations and we routinely measure this with the Zetasizer Nano.
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.

On-line zeta potential measurement is helping us to achieve a more cost-efficient water facility.
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.

Here at IU’s Nanocharacterization facility, the Malvern Zetasizer Nano is the ‘go to’ instrument for characterization of assembled product.

We very much value the customer service and training opportunities from Malvern. In particular, the rapid diagnosis of any issues through direct internet connection with the Malvern customer service team has prevented us from suffering production downtime.

The big plus of an on-line instrument is real-time monitoring, the value of which was really brought home to us during a recent treatment event. The on-line data we collected during the event gave us new insight into a modified operating scheme that we’re now capitalizing on.
The Malvern systems have proved highly effective, allowing us to further demonstrate the stability and purity of our products and how this may be translated into improving liquid biopharmaceutical formulations.
We’ve always been really happy with Malvern and while we’ve tried other companies, the necessary expertise was not there.

The [Zetasizer Nano] instrument is robust, easy to use and data acquisition is straightforward. It is as close to ‘student proof’ as it is possible to be!

The technical support that we’ve received has been a deciding factor in our decision to continue to work with Malvern. Malvern systems also provide the cutting-edge performance and reliability that we need.

The Zetasizer Nano has reliably delivered a substantial portion of data and continues to help drive our research.
As part of the multi-disciplinary lab at QMUL, materials and biomaterials research groups throughout the university, from engineers and chemists through to biologists and physicists, are benefiting from access to analysis using the Zetasizer Nano.
We’ve been running the Zetasizer APS continuously since 2012 and the real beauty is that we simply load the samples in multiwell plates, leave it to run, even overnight, and go back and pick up the results.
