Zetasizer Nano ZSP by Malvern Panalytical

"This is a great particle size analyzer. Straight forward and a great purchase for solution particle size determination."

"Great instrument and reproducible results. Looking for integration of new features, like Nanosight for number of particles measurement, in one instrument."

"This instrument is easy to use and the data is reproducible."

"It works well, but after one year it started giving bad measurements. Just to came and take a look to the instrument is 5000 dlls."

"Highly reproducible results obtained. Very easy to train for simple results interpretation. SOP's easy to export to replicate results at alternative sites"

"Very easy to use, needs more explanation on the PDI value and how to improve it."

"Its simple to use this instrument, but the results are great. There is a rudge number of available analysis. I recommend everyone working with nanoparticles."

"It is very easy to use and the manuals are well written"

"Good easy to use. Measure the size appropriately. Software is really helpful."

"The products we receive from Malvern are high quality and arrive at our lab in no time at all! The products fit well with each instrument and easily can be used for analysis. Malvern also provides many online tutorials and services, that we use regularly to ensure quality in our formulations and our research. i would recommend Malvern Instruments and products to any of my colleagues."

"It is an easy to use instrument. we obtained reproducible results. we recommend this system for nanoparticle characterization."

"Used a wide range of products from Malvern, ZetaSizer Nano for both size and zeta potential, FPIA for particle size and shape, MasterSizer for particle size analysis from nano to millimeter. All super amazing instruments."

"Easy to use Reproducible results Export reports with ease"

"The Malvern Zetasizer is very easy to setup and use. the SOP style walks through the pertinent parameters ensuring nothing gets missed. The software is very user-friendly, and allows for multiple levels of control (CFR 21/11). We have had very few problems with our instrument over the 10+years we have had it, and the few we have had were quickly addressed by Malvern. still a workhorse in our lab, and we continue to find new ways to incorporate the capabilities into our testing."

"The results are consistent with what we would expect from this instrument. The software is both intuitive and robust."

"The Malvern Zetasizer nano is a great piece of equipment (especially considering it is a "black box" that does most of the difficult stuff -- i.e. power settings, laser height, count rate monitoring -- for you). It's nice that there are some "advanced" features that allow you more control over these normally set features, and that built in macros allow you access to raw data such as the correlation and size distribution if you wanted to do your own fit. Some additional features which I think could be quite helpful would be to include not just a cumulant fit, but a CONTIN analysis (better for a greater variety of systems, especially polydisperse), and also the ability to select from the correlation data a range to analyze. For example, if the correlation data is perfect with a baseline at zero, and you know there is dust or other particulates in your sample that is causing this, to be able to "chop" the data where the exponential decay ends and have a fit of only that data."

"very easy to use, very important tool but way too expensive, results for polydispersed samples are hard to get and usually the results are very confusing..."

"The results are not stable. Many factors might affect the results."

"Zeta size range is good for measuring, Zeta potential, Microrheology, Protein mobility, Particle size, Molecular size and Molecular weight particularly of proteins. It will show you the aggregation status of your protein. I recommend it to be used for measuring, Zeta potential, Microrheology, Protein mobility, Particle size, Molecular size and Molecular weight."

"It provides the particle size distribution and changes of zetapotential of nanoparticles during experiments."
