Particle Size, Zeta Potential and Molecular Weight Analyser

The new SZ-100 dynamic light scattering (DLS) instrument analyses key particle physical properties including size, zeta potential, molecular weight, and second virial coefficient (A2).

Particle size measurements can be made from 0.3nm – 8µm at concentrations from 0.1mg/mL (lysozyme) to 40 wt % depending on sample properties. Zeta potentials from -200 to +200mV can be analysed manually or with the auto titrator. Molecular weight of small particles (<100nm) is measured from 1x103 to 2x107 g/mol. The SZ-100 is the only instrument that measures particle size at both 90° and backscatter (173°). Zeta potential is measured in unique disposable cells using carbon coated electrodes that greatly extend cell lifetime.
