BeNano 180 Zeta Pro

The BeNano 180 Zeta Pro is the 5th generation of nanoparticle size and zeta potential analyzers designed by Bettersize Instruments. The instrument features technologies such as Dynamic light scattering (DLS), phase angle light scattering (PALS) and static light scattering (SLS) to provide accurate particle size, zeta potential and molecular weight data.

The BeNano 180 Zeta Pro can be used to study suspensions such as polymers, colloids, self-assembling systems, macromolecules, proteins, peptides, antigens, antibodies and other nanoparticles.

Features

  • Dynamic Light Scattering (DLS) with top-end components, such as solid state laser source, APD detector and multiple detection angles (12°, 90° & 173°), for highly sensitive measurements of particle size distribution (hydrodynamic diameter) and polydispersity index in low and high concentration samples
  • Phase Analysis Light Scattering (PALS) for average zeta potential and zeta potential distribution measurements in a wide variety of samples such as with low electrophoretic mobility at high salt concentrations
  • Static Light Scattering (SLS) to determine weight-average molecular weight (Mw) and second virial coefficient A2 (B22) and diffusion interaction parameter kD
  • Viscosity measurement of samples through the use of tracer particles, ranging from 0.01 to 100 cP
  • Intelligent intensity and signal adjustment system according to signal-to-noise ratio
  • Wide temperature range from -10 °C to 110 °C ± 1 °C for thermal stability studies such as protein denaturation
  • Research-grade software including general purpose, cumulants and CONTIN analysis algorithms to resolve polydisperse samples with multimodal peaks
  • Variety of low cost disposable cuvettes such as capillary sizing cell that avoids sedimentation to allow the analysis of larger particles up to 15 μm
  • 21 CFR Part 11 compliance


Applications

  • Colloids, nano metals and metal oxides
  • Polymer latices
  • Antigens and antibodies
  • Pharmaceutical and HPC formulations
  • Investigation of temperature-sensitive colloids
  • Paints, coating materials, pigments, inks and toners
  • Study on polymerization process and reaction mechanism
  • Study on kinetics of self-assembly and other processes of macromolecular (de-)polymerization
