WYATT TECHNOLOGY WD3-04 STATIC SMOOTH DRUM ROLLER

The WYATT TECHNOLOGY WD3-04 Static Smooth Drum Roller is a precision instrument designed for advanced characterization of macromolecules and nanoparticles. It operates within a molar mass range of 0.0004409 to 2.2046 GDa and measures molecular sizes with radius of gyration (Rg) spanning 0.0003937 to 0.019685 inches. It supports hydrodynamic radius (Rh) measurements in both flow mode (0.000019685 to 0.011811 inches) and batch mode (0.000019685 to 0.03937 inches). The detector offers exceptional sensitivity, capable of detecting 0.000022046 lb of 100 kDa polystyrene in THF or 0.0004409 lb of BSA in PBS, with a dynamic range of 3,300,000:1. It utilizes a laser with a wavelength of approximately 0.025984 feet and features programmable laser power control from 10% up to 100%. The instrument includes a WRFC Standard flow cell with an internal diameter of 0.047244 inches operating at ambient temperature. Compact in size, it measures 22.83 x 14.17 x 10.24 inches and weighs 46.7 pounds. This device integrates static light scattering technology to accurately determine absolute molar mass, size, and molecular conformation, ideal for research in polymers, proteins, and nanoparticles. Its stable laser source, wide dynamic range, and precise molecular size measurement capabilities make it suitable for detailed macromolecular analysis in various solvent systems and experimental modes. The WD3-04 is widely employed in laboratories for polymer science, biochemistry, and nanotechnology applications where accurate molar mass and size measurements are critical.
