Partica mini LA-350

Laser Scattering Particle Size Distribution Analyzer

HORIBA's new LA-350 Laser Diffraction Particle Size Distribution Analyzer is the ideal combination of performance, price, and packaging. The LA-350 excels in applications as diverse as slurries, minerals, and paper chemistry. Based on the advanced optical design of previous LA-series analyzers, the LA-350 strikes a harmonious balance between high-functionality, easy operation, low maintenance, and cost-effectiveness.

Bench space is used efficiently due to the LA-350’s compact size (297 mm x 420 mm). The clever design and precision, high quality manufacturing ensure convenient, reliable operation and accurate results, now with a wider size range (0.1-1,000 µm).

In addition, access to world class HORIBA support and training comes with purchase of all HORIBA products. HORIBA offers scheduled service agreements, regular instructional videos, and scheduled classes. HORIBA customers not only have the best analyzers in the business ... they are the best analysts in the business.

Segment: Scientific
Manufacturing Company: HORIBA, Ltd.
  • Range: 0.1 - 1,000 µm which matches the widest range of applications with a performance equivalent to many other full range systems.
  • Compact Size: Crowded lab? Multiple locations? The compact size preserves bench space and makes it possible to transport the instrument to different locations within a facility or ship to remote locations for on-site testing where it is not practical to purchase an analyzer.
  • Fast Analysis: The highly-refined optical design and algorithm provides measurement results in three easy steps: click, add sample, and review data. Data can be obtained in as little as ten seconds.
  • Powerful Software: The LA-350 uses the same fully featured software package as our other LA-series analyzers, providing a wide range of statistical measures, data analysis, and presentation tools.
  • Ease of Use: With automatic alignment, a built-in ultrasonic system for sample dispersion, and a powerful pumping system, combined with the automation features of the software, sample analysis on the LA-350 is extremely easy and straightforward. Sample analysis can be a one-button operation.


  • Flexible Operation: Readily adapt to changing measurement needs with a wider size range and flexible software.
  • Simple Operation: One button operation is possible by using the methods and sequence options built into the software.
  • Fast Analysis: Get answers now with quick measurement and analysis.

Maximizing Soy Milk Quality Attributes through Particle Size Analysis
Maximizing Soy Milk Quality Attributes through Particle Size Analysis
In this note, the final result of soy milk processing is evaluated with particle size analysis. Particle size results give a quantitative measure of the soy milk that can be used to ensure consistent production and product quality.
Milk Homogenization Evaluation by Particle Analysis
Milk Homogenization Evaluation by Particle Analysis
Milk is an emulsion that is homogenized to reduce the average particle size, which improve its consistency and extends shelf life. The homogenization process is expensive and careful control of the process can improve quality and consistency and reduce operating costs.
Particle Analysis of Chocolate
Particle Analysis of Chocolate
Particle size of cocoa powder used in chocolate affects color and flavor strength. The industry refers to “mouthfeel” as a gauge of acceptability or rejection. If the particles are too large, it will not have a consistent creamy taste. Particle size also affects the level of bitterness when tasted.
Particle Characterization of Powdered Sugar
Particle Characterization of Powdered Sugar
Quality control is an essential part of sugar production. In this study, the LA-960V2’s ability to rapidly analyze particle separation and the particle size of powdered sugar at its de-agglomerated state is demonstrated.
