Excellent System!
Application Area: Nanoparticle characterization
"This system is very user friendly compared to other particle sizers I have used previously. The method builder allows you to easily analyze several characteristics of our nanoparticles. I would highly recommend this product."

Can't work with nanotechnology without this instrument.
Application Area:Analyze nanoparticles characteristics
"Super easy to use the product. The software is very simple, although they should add a standard values table for the materials instead the user has to search the values on literature. A super useful instrument for nanoparticle characterization."

No complaints.
Application Area:Particle size analysis
"No complaints - documentation for hourly qualification could be beefed up a little."

Manufacturer's ResponseReply, thanks for the review, however, we are a little bemused by the “hourly qualification” phrase could you contact us to explain further at https://www.malvernpanalytical.com/en/about-us/contact-us/? It’s not normally necessary to perform qualification at such a high frequency. Stay safe.

Easy-to-use yet powerful instrument.
Application Area:Raw material analysis for R&D
"The ZetaSizer Ultra is a dynamic, user-friendly instrument useful for a variety of applications. Malvern provides in-person training on the instrument and its theory that is very useful for newcomers to DLS and ELS measurements. There is a support team that consistently answers quickly with questions regarding interpreting data or other issues with the instrument. All and all a quality instrument and company to work with."

Fantastic bit of equipment. Go for the Ultra not the Pro version.
Application Area:Monitoring protein aggregation
"A very useful piece of equipment. representing good value for money. Had some zeta potential problems during first use but that was down to my sample preparation."

Manufacturer's ResponseMany thanks for the feedback, if you have any particular feedback on our after sales support we would love to hear from you further.
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 affords the ability to directly analyze particle concentration. The measurement of particle concentration is calibration-free, 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 VLPs, which were previously very challenging to measure.
The Zetasizer Ultra also provides the highest sensitivity zeta potential and electrophoretic mobility measurements using M3-PALS technology. Our affordable disposable folded capillary cells enable measurements in extremely low volumes, without direct sample-electrode contact, using our patented diffusion barrier method. The information provided by these measurements is an excellent indicator of sample stability and/or propensity to aggregate.
The addition of Constant Current Mode for measuring electrophoretic mobility and zeta potential in high conductivity media reduces errors that can be associated with electrode polarization at higher ion concentrations.
