HORIBA’s ground breaking optical design perfects the static light scattering particle sizing technique.

Advanced Detector Design

The number of detectors, angular range, and layout each contribute to overall system performance. 

Superior Instrument-to-Instrument Precision

The LA-960V2 is designed and built to provide the same experience regardless of manufacture date, operator skill, or geographic location.  Achieve unmatched instrument agreement without the hassle of correlation.

Automatic Laser Alignment in Seconds

Always make perfect measurements with computer-controlled laser alignment.  The alignment process is finished in only a few seconds with HORIBA's innovative approach.

Guaranteed Accuracy and Precision

The LA-960V2 is a highly refined particle size analyzer capable of accurately measuring NIST-traceable size standards within 0.6% of specification. Fully compliant with ISO 13320 recommendations regarding the measurement of materials on the D10, D50, and D90.

State of the Art Sampling Systems

Wet Measurement

Sample-to-sample analysis in less than 60 seconds

The HORIBA LA-960V2 wet circulation system is an easy, fast and very powerful dispersion system.  The standard  wet system offers a full package of a dispersant fill pump, liquid level sensor, circulation pump, 30 W in-line ultrasonic probe,
and drain valve, which is all software-controlled for true one-button operation.
This advanced design provides highly reproducible particle size results.

Dry Measurement

Automated, powerful dry powder dispersion

The LA-960V2 Powder Jet combines several unique and patented features to provide the most reproducible dry measurements.  Use the Auto Measurement function to control vacuum, air pressure, powder flow, start/stop conditions, measurement duration, and data processing. Designed to handle every application including small sample amounts, friable powders, and highly agglomerated materials.

  • Smart Scans – Trigger function
    This function allows for very precious materials to be measured accurately.
    When the sample amount is limited or low flow ability, the Trigger functions perfectly start and stop the measurement.
  • Self-Adjusting Powder Flow
    Historically, the biggest challenge in dry powder measurement involved establishing an even powder flow.
    The LA-960V2 Powder Jet has solved that challenge with a self-adjusting feedback loop to maintain a constant laser transmittance.
    This is a crucial factor in creating reliable, reproducible dry powder size measurements.
