Partica LA-960V2 – Horiba

Price Range: $60,000 – $105,000 (Estimated New)

Best For: High-End Throughput

The Horiba Partica LA-960V2 remains a dominant force in the high-end sector, known specifically for its ability to handle difficult, large-particle samples that other systems struggle to circulate. While an established platform, its continuous software updates and raw hardware power keep it at the forefront of the industry in 2026. It is built for speed and power, utilizing strong circulation pumps and a massive dynamic range to ensure no fraction of the sample is missed.

Key Specs

• Measurement Range: 10 nm – 5000 µm (5 mm)

• Measurement Cycle: 60 seconds (fill, measure, rinse)

• Light Sources: 650 nm Laser Diode and 405 nm LED

• Circulation: High-power centrifugal pump

• Optics: Enclosed optical bench for stability

Performance & Applications Speed and aggregate handling define the LA-960V2. The instrument allows for a complete measurement cycle—from liquid filling to rinsing—in under one minute, making it the ideal candidate for QA/QC labs processing hundreds of samples per day. Its upper detection limit of 5 millimeters is superior to many competitors, allowing it to accurately characterize coarse aggregates found in the construction, mining, and ceramics industries. The powerful circulation system prevents the sedimentation of heavy particles, ensuring that the distribution data reflects the true sample composition rather than just the fines that stay in suspension.

SYNC – Microtrac

Price Range: $65,000 – $110,000 (Estimated New)

Best For: Shape Analysis Integration

Microtrac’s SYNC analyzer addresses the limitation of pure laser diffraction by integrating Dynamic Image Analysis (DIA) directly into the same measurement stream. Laser diffraction assumes particles are spherical, which can lead to errors when measuring rods or flakes. The SYNC overcomes this by photographing the particles as they are diffracted, providing shape data alongside size distribution.

Key Specs

• Measurement Range: 0.01 µm – 4000 µm

• Technology: Synchronous Laser Diffraction and Dynamic Image Analysis

• Detectors: Fixed detectors covering 0° to 165°

• Camera: Integrated strobe LED for high-speed image capture

• Module: FLOWSYNC for wet dispersion

Performance & Applications The SYNC is indispensable for material scientists who need to understand why a particle distribution looks the way it does. For example, if a diffraction result shows a "tail" of large particles, the integrated camera can confirm whether these are genuine large particles or agglomerates of smaller ones. This simultaneous insight is crucial in the abrasive and metal powder industries, where particle shape directly influences flowability and packing density. The system allows users to switch between wet and dry modes rapidly, and the fixed-detector design eliminates the need for scanning components, increasing mechanical reliability over time.

BeNano 90 Zeta – Bettersize

Price Range: $30,000 – $50,000 (Estimated New)

Best For: Nanoparticles & Budget

While the previous models focus on broad-range laser diffraction, the Bettersize BeNano 90 Zeta utilizes Dynamic Light Scattering (DLS), making it the specialist for the nano-range. It offers a cost-effective solution for labs focusing exclusively on proteins, polymers, and colloidal systems. Recent updates to its optical system have improved its sensitivity, allowing for the measurement of samples with weak scattering signals.

Key Specs
