Bettersize BeNano 180 Zeta Max 02.18

BeNano 180 Zeta Max uses Dynamic Light Scattering (DLS), Static Light Scattering (SLS), Electrophoretic Light Scattering (ELS), sedimentation-based sizing, optical refraction, and Light Extinction-Dynamic Light Scattering (LEDLS) to measure particle size, molecular weight, rheological properties, zeta potential and its distribution, particle concentration of nanoparticles, and liquid refractive index. 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 both 173° and 90° for size and molecular weight measurements. The 173° detection position automatically adjusts according to the sample’s scattering ability to ensure accuracy across a wide concentration range, while the 90° optics allows size measurements with as little as 3 μL of sample. Scattered light is collected at 12° in the forward direction for zeta potential measurements. The BeNano system applies Phase Analysis Light Scattering (PALS) technology, combining fast-field reverse (FFR) and slow-field reverse (SFR) data to obtain both the average zeta potential and its distribution. Measurements are performed using disposable folded capillary cells to avoid cross-contamination. Optical signals are efficiently collected and transmitted through a single mode fiber-based system. A 0° module equipped with a PD detector and a CMOS detector enables particle concentration, refractive index, and sedimentation-based size measurements. Particle size: 0.3 nm - 15 μm Zeta potential measurement range: No actual limitation Mobility: > ±20 μm·cm/V·s Molecular weight: 342 Da – 2 x 10^7 Da Refractive index: 1.2 - 1.6 Particle concentration: 1x10^8 particles/mL - 1x10^12 particles/mL Sedimentation-based size: 1 μm - 50 μm 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, one RI cuvette, and 10 folded capillary cells.
