Key features

  • Measurement: Particle shape, particle size
  • Particle size range: 4 to 400µm
  • Dispersion type: Wet
  • Technology: Automated Imaging


  • Analysis parameters: Particle size distribution, D100, aspect ratio, circularity and radius-thickness ratio.
  • Optimized software: Identify
10,000 particles per minute. Automatic recognition of agglomerated powder further improves accuracy.



  • Sheath flow theory: Ensures each individual particle passes through the focal plane of the cell sequentially, eliminates particle overlapping and defocus issues.
