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.

Thank you for taking time to review the Ultra. We normally offer e-learning course places as part of the sale. If you have not received these or would prefer training at our or your site then please contact our US Customer Support Team.
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.

Thanks for taking time to review your Zetasizer Ultra and hope its adding to your formulations capabilities.
Reliable and repeatable results. This equipment makes life easier.
Polymeric nanoparticles, diatoms, silica nanoparticles, magnetic nanoparticles, phase separation
Reliable and repeatable results. This equipment makes life easier when you have to perform hundreds of measurements. The device is simple and pleasant to use, it is easy to teach new people how to use it. Service at the highest level, always ready to help. In addition, the company regularly organizes free webinars with specialists in the operation of the apparatus and the possibilities of its use.

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.
