This opportunity seeks a Dynamic Light Scattering Instrument with specified capabilities, including zeta potential measurement from 5 nm to 100 µm, sub-micron particle sizing, compatibility with mining and battery materials, and auto-titration with degassing across a pH range of 1 or lower to 13 or higher. The auto-titration must support step sizes smaller than 0.25 pH, and the software must be Windows-compatible with data logging and customizable analytical procedures. The award will be based on the lowest price technically acceptable methodology. Proposals must include a fully executed ANL-70 Request for Quotation, the ANL-70A Representations and Certifications, and the equipment's country of origin. Questions should be directed to the Contracting Officer.
