Bettersize BeNano 180 Zeta 02.11

BeNano 180 Zeta uses Dynamic Light Scattering (DLS), Static Light Scattering (SLS), and Electrophoretic Light Scattering (ELS) techniques to measure particle size, molecular weight, and rheological properties of nanoparticles, as well as zeta potential and its distribution. 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. Scattered light is collected at a backscattering angle of 173° for size and molecular weight measurements. The detection position automatically adjusts according to the sample’s scattering ability, ensuring accurate size measurement across a wide concentration range. Scattered light is collected at 12° in the forward direction for zeta potential measurements. Optical signals are efficiently collected and transmitted through a single mode fiber-based system. The BeNano system applies 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. Particle size: 0.3 nm - 10 μm Zeta potential measurement range: No actual limitation Mobility: > ±20 μm·cm/V·s Molecular weight: 342 Da – 2 x 10^7 Da 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 100 PS cuvettes, 50 caps, one glass cuvette, one capillary sizing cell, and 10 folded capillary cells.
