Zetasizer Advance Series Ultra (Red Label) for advanced characterization of nanoparticles and macromolecules in solution.

Capabilities:
-    Particle and macromolecule size.
      Measurement by Dynamic Light Scattering (DLS), ideal for nanoparticles, proteins, aggregates, liposomes.
-    Zeta potential.
      Analysis by Electrophoretic Light Scattering (ELS) to assess surface charge and colloidal stability.
-    Molecular weight.
      Direct determination for proteins and polymers via Static Light Scattering (SLS).
-    Concentration and weak interactions.
      Highly sensitive detection suitable for dilute samples and biological systems.

Applications:
-    Characterization of nanoparticles, extracellular vesicles, and liposomes.
-    Protein aggregation and stability studies.
-    Analysis of polymers and polysaccharides.
-    Development and quality control of colloidal formulations.
-    Monitoring the effect of pH, salts, or additives on the stability of dispersed systems.
