    New Size and Shape Particle Analyzer Announced!

    Microtrac announced a new instrument at Pittcon 2018! The new Microtrac Sync will provide customers with more information about their particles than ever before. By integrating the world’s leading laser diffraction technology with the leading dynamic image analysis on the same bench with the same GUI, Microtrac’s Sync is synchronizing size and shape measurement – one sample, one bench, one sample flow path, one sample cell, one analysis. Size alone is not good enough anymore.

    Laser Diffraction Systems

    Since the release of the 7991 in 1974, the first commercially available particle size analyzer, Microtrac has been at the forefront of delivering laser diffraction systems.

    Dynamic Light Scattering Systems

    Since the release of the UPA in 1990, Microtrac would go on to become the preferred manufacturer of Dynamic Light Scattering instruments for nano-particle measurements.

    Image Analysis System

    Whether you are searching for basic image analysis, 3D image analysis, or Online image analysis capability, Microtrac has a particle image analyzer to fit your needs.
