The Morphologi G3 provides an advanced yet easy to use particle characterization tool for the measurement of particle size and particle shape from 0.5 microns to several millimeters. In one instrument it offers the flexibility required for R&D and troubleshooting applications, and user-independent results and the validation required for automated QC analysis. The technique is often used in conjunction with laser diffraction particle sizing, to gain a deeper understanding of product or process behavior.


The Morphologi G3 measures the size and shape of particles using the technique of static image analysis. Fully automated and with integrated dry sample preparation makes it the ideal replacement for costly and time-consuming manual microscopy measurements.

  • Automated SOP control for unattended operation and reproducible results boosting productivity
  • Excellent quality microscope images ensuring accurate characterization
  • Integrated dry powder dispersion with accurate dispersion energy control automates sample preparation for repeatable and reproducible measurements of both fragile and robust materials
  • Advanced manual microscope control mode providing increased value as a shared laboratory resource
  • Rapid automatic particle counting on membrane filters
  • Powerful and intuitive software interface making both visual and statistical interpretation of your data easier than ever. 

How it works

The Morphologi G3 measures the size and shape of particles by the technique of static image analysis. There are three essential stages in the measurement process;

  • Sample preparation and dispersion
    This step is critical to getting good results; spatial separation of individual particles and agglomerates is the goal. The Morphologi G3SE has an integrated dry powder disperser which makes preparing dry powder samples easy and reproducible. The applied dispersion energy can be precisely controlled, enabling the measurement process to be optimised for a range of material types. Dispersion is achieved without explosively shocking the particles, avoiding the damage of fragile particles while ensuring strongly agglomerated materials are dispersed. Effective dispersion of fibres can also be achieved.
  • Image capture
    The instrument captures images of individual particles by scanning the sample underneath the microscope optics, while keeping the particles in focus. The Morphologi G3 can illuminate the sample from below or above, while accurately controlling the light levels. Polarizing optics can be used to study birefringent materials.
  • Data analysis
    The instrument measures a range of morphological properties for each particle. Advanced graphing and data classification options in the software ensure that extracting the relevant data from your measurement is as straightforward as possible, via an intuitive visual interface. Individually stored grayscale images for each particle provide qualitative verification of the quantitative results.
