The BeNano 90 Zeta: A Nanoparticle Size and Zeta Potential Analyzer

The BeNano 90 Zeta is the latest generation of nanoparticle size and zeta potential analyzer designed by Bettersize Instruments. The system is integrated with dynamic light scattering (DLS), electrophoretic light scattering (ELS), and static light scattering (SLS) to deliver accurate measurements of particle size, zeta potential, molecular weight, and rheological properties. Now with The BAT-1 Autotitrator, for analyzing the zeta potential as a function of pH and determining the isoelectric point (IEP) of a colloidal system. 

The BeNano 90 Zeta instrument is extensively used in academic and manufacturing processes of numerous fields, such as biology, chemistry, pharmaceuticals, chemical engineering, materials, food, etc.

  • Fast measurement capability—faster operations and editable results
  • Sensitive optical fiber detection system—effectively boosts signal-to-noise ratio, thanks to the excellent sensitivity of the optical system
  • Intelligent intensity adjustment—the intensity can be effectively adjusted in accordance with the signal-to-noise ratio
  • Disposable folded capillary cell—exceptional repeatability of zeta potential measurements and prevents cross-contamination
  • Phase analysis light scattering—measurement of zeta potential and low electrophoretic mobility
  • Intelligent algorithm of result assessment—intelligent assessment and processing of signal quality prevent the effect of arbitrary events
  • Capillary sizing cell—sample volume as low as 3 to 5μL and higher measurement precision for large particles
  • Multipurpose calculation modes—numerous integrated calculation modes cover various scientific research and application fields
  • Extremely stable optical design—offers highly repeatable results and does not need routine maintenance
  • A broad range of temperature control—modifiable temperature from −10°C to 110°C to fulfill various measurement needs and enable thermal stability analysis of specimens

BAT-1 Autotitrator

The BAT-1 Autotitrator is equipped with three high-precision titration pumps (with precision of 0.28 μL), and a magnetic stirrer, and is in combination with the BeNano series nanoparticle size and zeta potential analyzer for automatic acid-base titration and determination of isoelectric point (IEP). The pinch valve can close the circuit of the sample during the measurement, leading to high efficiency, accurate titration, good repeatability and the results being independent of operators. The disposable sample container can avoid the sample cross-contamination.
