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).

NANOTRAC FLEX & STABINO ZETA for particle size & zeta potential
In this product brochure, Mictrotrac MRB provides an overview with technical information on the NANOTRAC FLEX & STABINO ZETA for particle size & zeta potential measurements. Microtrac MRB’s NANOTRAC FLEX is a flexible nanoparticle size analyzer based on dynamic light scattering (DLS). It provides information on particle size, concentration, and molecular weight which promises faster measurement with higher precision, and better accuracy. The STABINO ZETA has been designed to provide an accurate determination of the zeta potential, colloidal stability, and fast titrations.
Understanding particle size, zeta potential, and stability in dispersion systems
This whitepaper explains why particle size, zeta potential, and stability must be evaluated together to fully understand and control colloidal systems. Particle size defines the structural framework of a dispersion, while zeta potential provides insight into interparticle interactions and aggregation behavior. However, only direct stability measurements reveal how formulations evolve over time through processes such as sedimentation, flocculation, and phase separation. Discover how by integrating these complementary parameters, researchers can better predict product performance, improve formulation design, and ensure long‑term stability across applications in pharmaceuticals, food, and materials science.
Measuring zeta streaming potential of cannabis emulsions simultaneously with STABINO ZETA and NANOTRAC FLEX
In this application note, Microtrac MRB demonstrates the simultaneous determination of several parameters from cannabis emulsions within a few seconds, including zeta potential, streaming potential, pH, and size range. Dynamic light scattering and zeta potential were used to characterize CBD nanoemulsion that was created using a microfluidizer. Five liquid solutions were involved in the creation of the final nanoemulsion with the desired particle size. The resultant cannabis nanoemulsions were analyzed using both the NANOTRAC FLEX and the STABINO ZETA to determine the surface charge density, stability, zero point of charge, and size distribution.
