The DynaPro® NanoStar®II is a cuvette-based dynamic light scattering (DLS) instrument used for the analysis of the size and size distributions of peptides, proteins, polymers, nanoparticles and emulsions. A separate, optimized static light scattering (SLS) channel offers true molar mass measurements.
The NanoStar IIis among the most sensitive, robust and reliable DLS detectors available for protein and nanoparticle analysis.
