Recommend for you
Application Area:Analyze partcle size
"I think the particle sizer is very easy to use, and it stays really accurate as long as routine alignment is performed to check the accuracy of the instrument."

Provides rapid data to support process optimization meaning fewer rejected batches.
Application Area:Particle size analysis of nano milled active pharmaceutical ingredients and virosomes.
"This instrument is able to produce reliable and reproduce able results with the minimum of method development. This enables rapid point of use data when the instrument is located in close proximity to the processing equipment. The small footprint and portable mature of the instrument aids this usage. Malverns technical knowledge and after sales assistance is of a high standard and extremely valuable when technical issues with a sample are encountered. The instrument is of a robust nature and required no maintenance or servicing other than periodic verification against a known standard.."

Important piece of equipment.
Application Area:Pharmaceutical Sciences, to determine size and zeta potential of nanoparticles
"Really good analysis. After use support is good. The instrument can be made suitable to needs. One issue that I get is that is really sensitive to impurities or undissolved particles of chitosan."
Manufacturer's ResponseThanks for the review - DLS is sensitive to oversized particles, good sample preparation is the key to good data, if possible centrifuge or filter samples that may have oversized particles present.

Accurate results with minimal work.
Application Area:Analyze particle size of emulsion polymers
"This instrument is the most basic model and is very easy to use. For the emulsions we are analyzing, this model with just the default parameters is sufficient. However, the software is easy to manipulate and has guidance and methods for common chemicals. Malvern technical support can also help you customize parameters for more unique chemicals. The instrument produces high quality, reproducible results. For those new to particle size analysis Malvern has easily accessible information on the website to help you better understand terminology and calculations automatically performed by the software. Software preparation only involves a few clicks of the mouse and can be learned in 5 minutes. The sample is inserted in disposable cuvettes, so clean up takes only a few seconds. The instrument requires 1 service visit per year, but otherwise requires little or no maintenance. The instrument improved our repeatability, was quick to learn and decreased previous clean up time so it was a good value for our lab."

Particle size distribution of clays is very fine and nano range, Zetasizer is very useful for developing nano clay product for our company
Application Area:Dealing with clay minerals and very useful to tool find out the rheological behaviour
"Particle size distribution of clays is very fine and nano range, Zetasizer is very useful for developing nano clay product for our company. Measuring zeta potential of Kaolin & Bentonite using Zetasizer revealed scientific understanding of many properties, which are important with respect to commercial use. Especially rheological behaviour of kaolin clay w.r.to charge and pH is being calculated using Zetasizer."
An entry level system for the measurement of particle and molecular size at a 90 degree scattering angle using Dynamic Light Scattering, and molecular weight using Static Light Scattering.
The Zetasizer Nano S90 is the perfect lower cost solution when the ultimate in sizing sensitivity is not necessary, or where identical results to a legacy system with 90 degree scattering optics are required. The Zetasizer Nano ZS90 incorporates three techniques in a single compact unit, and has a range of options and accessories to optimize and simplify the measurement of different sample types.
