Rapid, automated particle size and particle shape analysis

Morphologi 4 provides detailed morphological descriptions of particulate samples through static image analysis, enabling a greater understanding of both sample and process.  It can equally be used as an R&D tool to investigate challenging applications and in automated QC analysis where generation of robust, user-independent results and validation are required.

  • Broad particle size range, from 0.5 μm to over >1300 μm, enables size measurements of a wide range of samples
  • 20+ morphological parameters deliver a highly-detailed description for deeper understanding of your particulate material
  • SOP control, from sample dispersion to data analysis, provides simple and automated operation for robust, repeatable measurements
  • Automated ‘Sharp Edge’ analysis enables detection of even low contrast particles
  • Advanced manual microscope mode and ability to return to particles of interest enables an even closer examination of unexpected particles
  • High resolution microscope ensures quality particle images for optimum image analysis data
  • Integrated dry powder dispersion unit delivers reproducible sample dispersion, critical to achieving meaningful results
  • Dedicated sample presentation accessories enable measurement of a wide variety of sample types, including suspensions and filters
  • Advanced data exploration tools generate maximum sample knowledge
  • 21 CFR Part 11 software option ensures regulatory compliance
