Microtrac MRB’s NANOTRAC Flex is a highly flexible nanoparticle size analyzer based on Dynamic Light Scattering (DLS) which provides information on particle size, concentration, and molecular weight. It allows faster measurements with reliable technology, higher precision, and better accuracy. All of this combined into compact a DLS analyzer with a revolutionary fixed optical probe.

With the unique and flexible probe design and the use of the Laser Amplified Detection method in the NANOTRAC FLEX, the user is able to choose an appropriate vessel as a measurement cell to satisfy the needs of any application. This design also allows measurements of samples over a wide concentration range, monomodal or multimodal samples, all without prior knowledge of the particle size distribution. This is made possible through the use of the Frequency Power Spectrum (FPS) method instead of classical Photon Correlation Spectroscopy (PCS).

Key Features

  • Most flexible Dynamic Light Scattering ever
  • Unique external probe design
  • In situ particle sizing and monitoring
  • 180° backscatter DLS setup
  • Turn any vessel into a sample cell – no consumables required
  • External probe allows dip and measure
  • Universal solvent compatibility
  • Small footprint
  • Frequency Power Spectrum calculation model instead of PCS
  • Laser Amplified Detection – high signal to noise ratio
