Zetasizer range of Light Scattering systems for Colloids, Nanoparticles and Biomolecules

Zetasizer – Unique light scattering solutions for Proteins and Nanoparticles.

The Zetasizer range of instruments uses dynamic, electrophoretic and static light scattering technologies to measure hydrodynamic size, zeta potential and absolute molecular weight.

The Zetasizer series comprises:

• Five systems for characterizing the size and zeta potential of colloids
• Two systems optimized for measuring the size and molecular weight of proteins

Technology - Unequalled sensitivity and versatility are achieved using the latest technology:

• Dilute and concentrated samples can be measured using the patented NIBS optics incorporated into the Zetasizer Nano S and ZS.
• Zeta-potential is measured using the leading technology in the field – M3-PALS.
• Proteins and other biomolecules can be measured with unrivalled accuracy and precision by the Zetasizer μV and APS using a single-mode fibre, high power laser and focussed optics.

Applications:

• Colloids – Measure the size of dilute and concentrated systems plus zeta potential.
• Optimise stability, improve shelf life, speed up formulation development.
• Automated change of pH and conductivity using autotitrator.
  
• Nanoparticles – The sensitivity to measure sizes below 1nm.
  • Study production processes.
    
• Proteins – The ability to measure 2µL of sample AND the sensitivity to measure the size of picograms of material.
  • Determine presence of aggregates, screen for crystallisation conditions.
  • Automated plate sampler system with no compromise in sensitivity.
