Zetasizer allows quick, low volume measurements for single samples
Nanoparticle characterization
The equipment allows for the measurement of different types of samples with a wide range of concentrations. The use of different cuvettes allows to use as little as 40 microliters of sample which is really good when your samples are precious. Data generated is readily available and the software is fairly straightforward to use although some of the previous versions had features that this one doesn't seem to have like the possibility of correcting sample names in the graphs that was really handy for publications. If you are measuring multiple samples it can be a bit slow so a multi well or cassette system would be very helpful to speed up data acquisition.

Reply for repair took too long
Sample analysis
After training, zetapotential function is not working. It took several weeks before we got answer for repair.

Excellent system for characterizing nanoparticles
Nanoparticles
Excellent system for characterizing nanoparticles in terms of their Physicochemical properties (size, concentration, polydispersity, and zeta potential). I like the system because it consumes only a few microliters of precious samples to determine and analyze all the properties mentioned above. I highly recommend this system for particle analysis.

Thank you for taking time to review us and I am pleased you find the speed and data quality advice useful in your work.
Very good
Particle size distribution and zeta potential measurements are used to study particle synthesis.
We use it to evaluate nano-sized particles that we synthesize ourselves. The use of disposable cells reduces contamination problems. We have been using it for a long time and have not experienced any malfunctions except for the titration device. We are very satisfied.

Excellent device and good support!
Nanoparticle Size and Zeta Potential
Product Review for Malvern Panalytical Zetasizer Ultra Red (Used Device). I recently purchased a used Malvern Panalytical Zetasizer Ultra Red, and overall, I am extremely satisfied with the experience. The decision to buy a used device at a lower price was a fantastic opportunity, especially after receiving a thorough introduction to the product in our lab. The entire purchasing process was smooth, and I felt well supported by the contact person, who was always available and helpful. When the device arrived, I also became the primary user. We initially had some trouble reaching the support person for the user training, but thankfully, our previous contact quickly stepped in and provided us with an impromptu training session. This was handled very efficiently and in a friendly manner, making the process seamless. As for the device itself, we've encountered no issues so far. The only minor difficulty we faced was transferring old data to a new computer. While we did receive assistance with this as well, it would have been helpful to have a more detailed online guide available for such tasks. In summary, my experience with the Zetasizer Ultra Red has been overwhelmingly positive, both in terms of the product and customer support. I would highly recommend it, especially if you have access to the right support team!

Thank you for taking time to review your Zetasizer and I am sorry to hear that our training support was not as seamless as we would have wanted. We will look into this and hopefully learn how we can improve.
Good one
Product quality control analysis
A really good instrument to analyze sizes, one thing I would like to have is the training sessions by the vendor before I start using it.

Reliable results, straightforward and user-friendly software, great technical support
To measure the size, dispersity and surface charge of nanoparticles
We use this device to measure the size, dispersity and surface charge of nanoparticles. The Software is straightforward and user-friendly. The instrument is ultimate, small and portable. The combination of this device with the new autosampler developed by Malvern is a great idea to increase the efficiency of the device and save the user time.

I've been using Malvern Zetasizer's since 2014. I used two other brands of DLS instruments, but none of them were as user-friendly as the Zetasizer. My team recently had two trainings from Malvern. They were really helpful, and it was good to refresh our knowledge.

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.

Dynamic and electrophoretic light scattering and their use in lipid nanoparticle and liposome research
In this application note, examples are presented of how dynamic light scattering (DLS) and electrophoretic light scattering (ELS) can be used in the characterization of liposomes and lipid nanoparticles to understand their suitability for a range of different applications.
Measuring the concentration of adeno-associated virus with multi-angle dynamic light scattering
For virus development and production, it is important to know the virus concentration at different stages of the process, to optimize the clone used as well as the production yields. For example, instances such as clone screening, multiplicity of infection (MOI) optimization and adaptations of cell culture methods are instances when virus concentration, or virus titre as it is also commonly called, is of interest.
