Laser Particle Sizer


The FRITSCH ANALYSETTE 22 NanoTec laser particle sizer has a measuring range of 0.01 – 2100 µm that makes it the ideal instrument for particle size analysis, whether is in production, R&D as well as quality control. The instrument is extremely easy to operate and can produce result in a short analysis time.


  • Measuring range 0.01µm to 2,000µm
  • Especially high measurement precision through the analysis of 110 channels
  • Fast and automatic particle size analysis
  • Simple measurement with short measuring times
  • Consistent reproducibility - reliable comparability
  • User-friendly operation
  • Fast and simple cleaning
  • Quick change between wet and dry measurement

The ANALYSETTE 22 NanoTec is the ideal Laser Particle Sizer for the determination of the particle size distributions of powdery samples, of solids in suspensions and of emulsions. The instrument is perfectly suitable for the utilisation in production and quality control as well as in research and development.
