Products from LS Instruments

  • LS Spectrometer

    Product LS Spectrometer

    Dynamic and static light scattering for powerful particle characterizationThe LS Spectrometer is a goniometer based multi-angle static light scattering (SLS) and dynamic light scattering (DLS) instrument for particle characterization. It is a modular platform enabling a high degree of customization. Even in its basic configuration, the LS Spectrometer is one of the most sophisticated instruments on the market and is particularly well suited as an entry-model. Should your demands on the device increase over time, the LS Spectrometer can easily be upgraded to the 3D LS Spectrometer configuration at any time. Our patented modulated 3D Cross-Correlation technology opens up the world of error-free particle characterization of even highly concentrated samples.

  • NanoLab 3D

    Product NanoLab 3D

    Error-free particle sizing even at high concentrationConventional DLS instruments carry the risk that multiply scattered light can lead to incorrect particle size measurements without ever warning you. Especially with concentrated samples, complex sample preparation and dilution is necessary. This is exactly where our NanoLab 3D comes in.

    The NanoLab 3D is a compact DLS instrument for particle sizing that is based on the groundbreaking and patented Modulated 3D Cross-Correlation technology. It efficiently suppresses multiple light scattering and therefore sample dilution is no longer required for most samples.

  • RheoLab

    Product RheoLab

    Advanced optical rheologyThe DWS RheoLab is an optical rheometer. It provides access to the sample's viscoelastic properties over an unmatched frequency range and enables the study of textures and microstructures while requiring only small sample volumes. Since the measurements are contact-free and non-destructive, the use of a tightly sealed sample cell allows studies of stability or shelf-life over long periods for highly viscoelastic and fragile microstructures. Based on the powerful DWS Microrheology technique, the RheoLab is ideally suited for a wide range of viscoelastic samples, including polymers, microgels, protein solutions, emulsions, particle suspensions, dairy, and cosmetic products.
