LS Instruments makes high end light scattering instruments for multi-angle Static and Dynamic Light Scattering (MADLS/DLS/SLS) along with microrheology using Diffusing Wave Spectroscopy (DWS). Particle sizing, distribution, molecular weight, G' and G'', rheology, Rg, particle shape, A2, Mw. Small Angle Scattering (SAS) is our newest instrument


  • DWS RheoLab III from LS Instruments
    Optical microrheology has emerged as one of the most important new techniques to study and characterize rheological properties of complex fluids! This commercial automated instrument makes accurate measurements....

  • Measure mechanical properties of natural or formulated polymers, surfactants, micelles, thickeners, etc.

    The DWS RheoLab measures conveniently and quickly using optical rheology. The instrument measures Diffusing Wave Spectroscopy (DWS) to calculate rheological curves that can directly be compared to conventional mechanical rheometer measures in oscillatory mode.

    Fully automated DWS Microrheology
    Applicable to all homogeneous transparent or opaque samples
    Fluid with a large range of viscosities from 0.1 mPa∙s to 1000 Pa∙s can be measured
    Storage and loss moduli G'(ω), G''(ω)  in a frequency spectrum 0.1 Hz to 10 MHz*
    Elasticity range from 1 Pa to 50 kPa
    Computes the mean square displacement (MSD) of particles
    Contact-free. No mechanical force applied to the sample: ideal for stability or shelf life studies
