S3500 – Particle Size Analyser

The industry preferred laser diffraction analyser, ideal for particle characterisation.

Microtrac-S3500-Laser-Diffraction-Instrument


The Microtrac S3500 is the first particle size analyser that uses three precisely placed red laser diodes to accurately characterise particles like never before. The patented Tri-Laser System provides accurate, reliable and repeatable particle size analysis for a diverse range of applications by utilising the proven theory of Mie compensation for spherical particles and the proprietary principle of Modified Mie calculations for non-spherical particles. The S3500 measures particle size from 0.02 to 2800 microns.

Applications for the Microtrac S3500:

Microtrac S3500 features:

  • Tri–laser, red, multi-detector, multi-angle optical system
  • Algorithms that utilise Mie compensation and Modified Mie calculations for non-spherical particles
  • Measurement capability from 0.02 to 2800 microns
  • Wet and dry measurements
  • Fixed detectors and lasers
  • Enclosed optical path ensures complete protection of the optical components leading to little or no operator intervention
  • Small bench footprint

Microtrac S3500 benefits:

  • Utilising three red lasers, increases the range of measurement, giving you the flexibility to conduct analysis on a wide range of samples
  • Proprietary Modified Mie calculations allow users to accurately measure complex particles that other particle analyser struggle to accurately characterise
  • Seamless transition from wet to dry measurement reduces down time
  • Fixed detectors provide rugged durability and assure proper positioning
  • Small bench footprint reduces demand of valuable laboratory space
