BeNano 90 Zeta: A Nanoparticle Size and Zeta Potential Analyzer

Bettersize Instruments has designed the next-generation nanoparticle size and zeta potential analyzer, called BeNano 90 Zeta.

The analyzer is incorporated with static light scattering (SLS), electrophoretic light scattering (ELS) and dynamic light scattering (DLS) to provide accurate measurements on particle size molecular weight and zeta potential.

The BeNano 90 Zeta instrument has a brief measurement duration and an easy-to-use interface that make it an extraordinarily robust nanoparticle size and zeta potential analyzer.

The BeNano 90 Zeta analyzer is widely utilized in academic and manufacturing processes of various fields, like pharmaceuticals, chemistry, biology, food, materials, chemical engineering, etc.
