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.

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.
