The BeNano series is the latest generation of nanoparticle size and zeta potential measuring devices. This system combines dynamic light scattering (DLS), electrophoretic light scattering (ELS) and static light scattering (SLS) to provide accurate measurements of particle size, zeta potential and molecular weight. The BeNano series is widely used in both academic and industrial applications in various industries, especially in biotechnology and life science, pharmaceutical, food and chemical industries.
The autotitrator BAT-1 is compatible with the BeNano series and is an ideal option for the automatic determination of the zeta potential of a sample in dependence of the pH value as well as the determination of the isoelectric point (IEP). It is equipped with three high-precision titration pumps with an accuracy of 0.28 μL. The appropriate titrant is automatically selected by the system and the addition volume is continuously adjusted using an intelligent routine.

The DLS Flowmode Option is a special setup for the DLS versions of the BeNano series to measure the particle sizes of individual fractions in high resolution in conjunction with connected separation process equipment (e.g. GPC, FFF). The option is available either only as a flow cell for recording the intensity distribution or additionally with a BFC signal collector for simultaneous recording of the RI or UV curve and thus direct measurement of the volume and/or number distribution curve.
