DynaPro NanoStar II Dynamic Light Scattering Detector by Wyatt Technology Corp.

The DynaPro^® NanoStar^® II is a unique cuvette-based DLS instrument used for the analysis of proteins, gene therapy vectors, viruses and virus-like particles, promiscuous inhibitors, micelles, liposomes, lipid, and metallic nanoparticles, and more. To accommodate scarce and precious samples, specially designed quartz cuvettes afford robust, accurate measurements with as little as 2 µL of solution, while our proprietary disposable cuvettes provide comparable sensitivity with as little as 4 µL

Walk-up operation with DYNAMICS^® Touch™

The NanoStar is the only DLS instrument to provide a fully integrated, walk-up measurement experience. No need to boot up your lab PC, launch the DLS software, connect to the instrument and worry about where your data files are stored. DYNAMICS Touch is an intuitive—yet capable—DLS measurement app that resides right on the NanoStar. Via the full-size touch screen display, DYNAMICS Touch guides you through the entire setup and measurement process. It tells you if the data quality is sufficient for confidence in the results, and displays them instantly. Data files and concise PDF reports can be stored on the instrument, transferred via the network or downloaded to a flash drive. You can even send the report to your phone!
