The new Zetasizer Ultra is our most advanced system for the measurement of particle and molecular size, particle charge and particle concentration, and represents the most intelligent and flexible instrument in the Zetasizer Advance range.
Our flagship model enjoys all the benefits afforded by ZS Xplorer software, in terms of ease of use, analysis speed and data confidence, and also offers unique measurement capabilities like Multi-Angle Dynamic Light Scattering (MADLS®) and in the Red Label version DLS Particle Concentration, to offer even greater insight into your samples.
The Zetasizer Ultra is the world’s most capable combined DLS and ELS system, incorporating Non-Invasive Back Scatter (NIBS) and, uniquely, Multi-Angle Dynamic Light Scattering (MADLS) technology for the measurement of particle and molecular size. NIBS provides the versatility and sensitivity to measure over a wide concentration range, while MADLS permits a higher resolution view into your sample’s size distribution for those critical measurements.
An extension to MADLS on the Zetasizer Ultra Red Label affords the ability to directly analyze particle concentration. The measurement of particle concentration is suitable for a wide range of materials, requires no or little dilution, and is quick to use – all of which make it ideal as a screening technique. This is a unique capability of the Zetasizer Ultra which can even be applied to samples such as viruses and virus-like particles (VLPs), which were previously very challenging to measure.
Key features of the Zetasizer Ultra include:
