Zetasizer Nano Z by Malvern Panalytical

"I had been working with this equipment for over 7 years and I can only say that it is perfect for characterizing and studying colloidal material for a wide range of materials, and is undoubtedly the gold standard for characterizing colloidal dispersions. Undoubtedly, it is an excellent product, which allows a wide possibility of colloidal studies and provides the characterization of nanomaterials simply and quickly. The software of the equipment is very intuitive and provides a fast characterization for common users, and also allows customization for a wide range of advanced analysis. Malvern's support is excellent, answering questions extremely quickly, as well as the excellent quality of the equipment manual, the technical notes and the webinars that allow a deepening of the user with the technique for better use of the equipment. In general, the equipment has allowed us from the initial characterization of the most diverse nanomaterials, to optimize their synthetic parameters, to specific characterizations and studies for publications in indexed journals. In addition, many companies contact us for sample evaluation by measurements. DLS and zeta potential, so we consider this equipment the gold standard for nanomaterial characterization and colloidal studies in our laboratory because it has fast, repeatable analyzes with excellent quality, and the automation option of the auto titrator facilitates the obtaining of the profiles. zeta potential of the materials as a function of pH and the wide temperature range allows the testing of sample aging or studies of phase transitions in polymers. Because of all these possibilities and facilities, this is undoubtedly a money-saving device and in the long run it is undoubtedly responsible for a great saving of money and time by allowing fast and excellent quality characterizations."
