⭕ VASCO-3 Dynamic Light Scattering Particle Size Analyzer (1 nm - 6 µm) In as new condition, 18 months old. A unique instrument for nano- to micro- particle size measurements in suspensions. The measurement principle is based on Dynamic Light Scattering (DLS) of backscattered light. Combines back-scattered light detection and ability to control sample thickness avoiding multiple scattering errors for optimal results. Allows for accurate measurements in highly concentrated and dark suspensions. Can be collected or shipping.
