The LA-960 uses Mie Scattering (laser diffraction) to measure particle size of suspensions or dry powders. The speed and ease-of-use of this technique makes it the popular choice for most applications.


This latest evolution in the LA series advances scientific knowledge for tomorrow’s world through intuitive software, unique accessories, and high performance. The LA-960 continues HORIBA’s proud tradition of leading the industry with innovative design.


Performance that matters

  • Measure particle size between 10 nanometers and 5 millimeters
  • State of the art nanoparticle measurement resolves peaks at 30 nanometers
  • Suitable for suspensions, emulsions, powders, pastes, gels, and creams
  • Easy to use dry powder accessory, read the PowderJet page for more information
  • Requires only micrograms* of sample, minimizing cost of analysis
  • Flexible, fully automated measurement sequences maximize precision and method compliance
  • Excellent reproducibility and unit-to-unit agreement, read the Gage R&R Study for more information
  • Measurements in less than 60 seconds boost productivity
  • Based on the ultra-durable LA-950 platform, noted for its reliability

Software that grows to meet your needs
