Bettersize BeNano Zeta 02.13

BeNano Zeta uses Electrophoretic Light Scattering (ELS) to measure zeta potential, zeta potential distribution, electrophoretic mobility, and conductivity of nanoparticles. The system is equipped with a 50 mW, 671 nm solid-state laser (10 mW, 633 nm He-Ne laser available upon request) and an APD detector, collecting scattered light at a forward angle of 12°. Optical signals are efficiently collected and transmitted through a single mode fiber-based system. The BeNano system adopts Phase Analysis Light Scattering (PALS) technology, combining fast-field reverse (FFR) and slow-field reverse (SFR) data to determine both the average zeta potential and its distribution. Measurements are performed using disposable folded capillary cells to avoid cross-contamination. Zeta potential measurement range: No actual limitation Mobility: > ±20 μm·cm/V·s A high-performance Peltier temperature control module precisely regulates the cuvette temperature between -15°C and 120°C. The BeNano research-grade software provides over 100 output parameters, standardized SOP programs, statistical reporting, and an integrated report designer. The software is backward compatible. The main unit includes 10 folded capillary cells.
