⭕ VASCO-3 Dynamic Light Scattering Particle Size Analyzer (1 nm - 6 µm) In like New condition. Unit is less than 18 months old. Checked, Tested and everything is in full working order. 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 arrange shippings.
