DynaPro NanoStar II Dynamic Light Scattering Detector

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, viruses, nanoparticles and emulsions. A separate, optimized static light scattering (SLS) channel offers true particle concentration and molar mass measurements.

Offering walk-up, guided operation so even novices can make quality measurements in just seconds, the NanoStar II is among the most sensitive, robust, and reliable DLS detectors available with powerful software that experts will appreciate.
