Beckman Coulter LS™ 200 Series


LS™ 200 Series

The Beckman Coulter LS 200 Series is a system of multifunctional particle characterization tools. Its patented state-of-the-art, laser-based technology permits analysis of particles without the risk of missing either the largest or the smallest particles in a sample.    
The LS technology is based on theories of light scattering. The LS differs from other laser-based instruments by virtue of its wide dynamic size range, number of size channels and sample measurement options.
