Zetasizer Nano ZS by Malvern Panalytical

"I have been using these instruments since 2014. It is working well, the data export and other many options are helpful for the researchers."

"Reproducible results"

"The instrument is used every day by laboratory technicians and Ph.D. students. Sample preparation is very easy and reproducibility of results is guaranteed. Using this instrument, we have developed several studies for chemical companies and published more than 4 articles of research. It's also a precious tool for student demonstrations making it very useful for teaching also. "

"Worked effectively and has good troubleshooting capabilities."

"Excellent size data with various types of particle size distribution e.g. by intensity, by volume and by number. Easy to use"

"High quality data"

"This analyzer is very helpful in drinking water treatment operation. It helps the operators to adjust the coagulant dosage in just few minute. It is user friendly. It was running for 6 years without major maintenance, and it is still give very reliable results"

"The Zetasizer Nano ZS has very intuitive software, samples are easy to manipulate with, and the results of measurements have high reproducibility. Compared to similar devices we have used in other laboratories of our partners, this one is truly the value for money and is much easier to use. Also, it is sample-friendly, due to its NIBS technology."

"The instrument is being applied from 8 am until 8 pm, for students in research work, for PhD students and for technicians. It is very easy to explain to them how it works, and the effectiveness of measurements are of very high accuracy. We have been using this instrument for the last 5 years andvit shows robustness and precision on measuring. Either size diameter, or zeta potential are determined here. In both cases, the instrument works very well."

"Industry standard, easy to use product. Colleagues all accept data generated by this product."

"It is easy to use, but samples need dilution before tests, which makes the zeta potential less accurate. It depends on the sample preparation, so tests results can be quite different."

"We use this product regularly to measure the characteristics of our nanoparticles - surface charge, size, PDI. It's super easy to use; my undergraduate researchers are able to jump right in and analyze their data. The videos through the Malvern website are also very helpful to my students."

"It was very easy to start using the instrument, but you need to be cautious for data misinterpretation with such easy-to-use instruments. Good amount of materials and support available online. Can't imagine working with nanoparticles without DLS anymore."

"Easy to handle instrument that provides a wide spectra of usage. As a newbie you will learn quickly how to take your measurements and after a few runs you will start to learn the mechanics and the possibilities of the machine. The sample preparation is really easy for the zeta sizer. It is highly tolerant to concentration issues and polydispersity. "

"The instrument is easy to use and the support is great. I highly recommend users to attend the seminars that Malvern provides, although this is not necessary to start using the instrument. I would recommend they use a test protein first like BSA, for which lots of data is available from Malvern and others. The Application notes were also very helpful and technical experts were extremely helpful."

"It is an effective product, if used properly. The documentation is wonderful, and does a great job of explaining the science behind the equipment. Unfortunately, it's design is not aligned well with usability, as at the lab I worked in, I was the only one who read the manual, but I was also the only one who used it the way the manual described"

"Such an easy instrument to run nano particles in various dispersants with low volumes for size and zeta potential. Easy use of various cells to cover all categories. The auto titration unit is also very efficient in producing pH, Iso Electric and titration results. The Malvern customer service people are just an email away when help or service is needed. This is one our most used and valued particle analyzers in our lab!"

"The machine is very easy to use. It is easy to set up a new method with the parameters we use for testing. The old results from previous testing is easily accessible to get. The only thing is that the software, whenever I tried to export an excel file, it would never work. Otherwise, the machine works beautifully and I am happy with the test results I have gotten."

"The instrument offers a broad and extensive number of analytical tools that are very useful in nanoparticle R&D. The instrument and software are very user friendly. Result acquisition, analysis, data review and export are consistent, smooth and effective. Measurements are sensitive and accurate, leading to high quality and reproducible results. Settings/format viewing is easily customization for application needs and SOPs are straightforward to create and use."

"Able to receive good quality results. Standard is reproducible on a weekly basis. Bad quality samples are given a quality report that explains why the sample may not have worked on the instrument. Easy prep. Quick analysis time."

"The Zetasizer Nano ZS streamlines particle size testing better than any other instrument on the market. It is a very simple and user friendly instrument. It is incredibly easy to make adjustments on the fly, and the software keeps all of the data and files extremely organized and quite accessible."

"Results and further analyses are easy to perform. Results are reproducible. Relevant cuvettes are prone to scratches meaning not efficient to use for long"

"We've had a Malvern Zetasizer Nano ZS for 2 years. Mainly running liquid nanomaterial samples for particle size and zeta potential analysis. The instrument and software is easy to operate. Most results obtained were reliable. One thing that I don't like is sometimes the software could crash at the beginning of the run. It seems got fixed with new updated version."

"It works well with user-friendly software. Different tabs provide insight about the data, especially when the data does not seem good. Looking into the correlogram and check the expert advisor does help understanding the problem. Also using the trend tab helps to compare different measurements."

"The zetasizer nano ZS gives excellent data and is much easier to use than competitor's instruments. I was blown away by the simple functionaility when I first used the instrument. It is the standard in DLS and zeta potential measurements today."

"I've been using the Malvern nano ZS for almost over 4 years. It is very well known as DLS (dynamic light scattering). My research is biomolecular imaging with several types of nanoparticles. So, I really need the size and zeta-potential data for my research. As I know, most of the researchers are using Malvern DLS instrument. I've submitted several papers and been working on a patent with this instrument. For the science, the essential is the most important. This instrument is the essential of my research."

"Our Zetasizer has been imperative in allowing me to analyze my drug-loaded polymeric nanoparticle formulation batches with consistent results. I have looked at particle size and zeta potential and always received good results, that were comparable to similar formulations. Instrument is easy to use and allows for numerous analytical combinations."

"Used by many researchers, easy to use, robust instrument"

"It is one of the best product from Malvern. It is so simple to use and the performance is excellent and reproducible."

"The easiest most reliable instrument. Never breaks. Simple to use. Zeta potential does have a large error margin but for the ease of use and low cost to operate worth the 2 min to set up a run. Backscatter feature is nice for smaller particles that would otherwise not be seen."

"Easy to use, but could have more technical assistance with setting up parameters for SOPs such as when it might be better to use forward versus backscatter. More expansive refractive index/absorbance preloaded."

"The Nano ZS is user friendly, gives reproducible results, and helps by giving you advice for better sample preparation."

"The instrument produces very reliable data. Performing the measurements as well as the data manipulation is easy and convenient. It can go down to low sizes which was important for my research."

"For years been used in our lab to measure size and surface charge of different nanoparticles as: SLN, liposomes, niosomes, magnetic nanoparticles. Perfectly functioning still. "
