BeNano series

The BeNano series for nanoparticle analysis

Particle characterization from 0.3 nm to 15 µm in terms of size, molecular weight and zeta potential by means of DLS, SLS and ELS

The BeNano series is the latest generation of nanoparticle size and zeta potential analyzer designed by Bettersize Instruments. Dynamic light scattering (DLS), electrophoretic light scattering (ELS) and static light scattering (SLS) are integrated in the system to provide accurate measurements on particle size, zeta potential and molecular weight. The BeNano series is widely applied in academic and manufacturing processes of various fields including but not limited to: chemical engineering, pharmaceuticals, food and beverage, inks and pigments, and life science.
