Malvern Panalytical Introduces New Zetasizer Pro And Zetasizer Ultra


Malvern Panalytical has announced two new additions to its Zetasizer range, the Zetasizer® Pro and Ultra systems.

Designed to increase confidence in decision-making within key analytical workflows associated with product development and quality control, the new systems have been built on the heritage of the market-leading Zetasizer Nano range, and are already the proud recipients of a Red Dot 2018 design award.

These new flagship instruments deliver significant improvements in the quality and speed of particle size, molecule size and zeta potential measurements, using the techniques of dynamic and electrophoretic light scattering.

Nanomaterials product manager at Malvern Panalytical Darrell Bancarz said: “The Zetasizer Pro and Zetasizer Ultra are the result of extensive customer understanding, research and testing, which has enabled us to develop a more intelligent and intuitive way of making light scattering measurements.

“We’ve introduced capabilities that halve sample preparation and measurement times, while providing more stable and reliable results. The application of revolutionary new measurement approaches delivers extended materials insight, enabling true product and process optimisation.”

Developer and manufacturer of high-performance nanoparticles and microparticles Blacktrace Holdings was clear about the impact of the new technology on its work. Head of particle works Pavel Abdulkin said: “The Zetasizer Ultra has dramatically increased our sample throughput, enabling us to accelerate our particle development cycle from 12 months to around a month.”

The Zetasizer Pro and Ultra systems are controlled by groundbreaking ZS Xplorer software, introducing new sample-centric workflows, which make method design and data analysis more straightforward for new users, while preserving full accessibility for users experienced in the application of light scattering methods.

New analysis capabilities answer, for the first time, key issues associated with the presence of dust or aggregates when applying dynamic light scattering for particle and molecular characterisation, filtering these from the results to give a truer overall picture of the sample. This is supported by integrated, deep-learning empowered data quality guidance, offering the user instant feedback on their results and providing actionable advice on how to improve poor quality data.

A key differentiator of the Zetasizer Ultra is its patented Multi-Angle Dynamic Light Scattering (MADLS®) technology, which automates multiple-angle size measurements, providing higher resolution and more complete particle size distributions.

MADLS also enables calibration-free particle concentration analysis for a wide range of materials, resolving the individual concentrations of different size populations.

The new disposable capillary sizing cell provides the ultimate in non-destructive, low volume (3μl) analysis, extending the upper range to 10μm and delivering high-quality data while reducing cost.

The Zetasizer Ultra’s speed and ease-of-use are uncompromised by these unique and powerful capabilities, making it the most advanced light scattering system available.

Zetasizer systems are used across many industry sectors worldwide, delivering value in the control and optimization of processes, and the improvement of product quality, stability and performance. They are ubiquitous in academic settings, indispensable in a wealth of application spaces and referenced in tens of thousands of peer-reviewed publications.
