Laser diffraction particle size analyzer
Achieve precise particle size analysis with laser diffraction technology, ensuring accurate characterization for diverse applications, from powdered metals to pharmaceutical ingredients.

Measures Particle Size and Distribution
The S3500 from Microtrac Retsch GmbH is a Laser Diffraction Particle Size Analyzer designed for precise particle characterization across various industries. What sets the S3500 apart is its patented Tri-Laser System, employing three strategically positioned red laser diodes to accurately analyze particles, ranging from 0.02 to 2,800 µm, with both spherical and non-spherical shapes. It smoothly transitions between wet and dry measurements, reducing downtime and maximizing lab efficiency. This analyzer is ideal for applications including beverages, pharmaceuticals, metal powders, and more, aiding in quality control of end-products like chemical catalysts and lithium-ion battery electrodes. Designed for bench-top operations, it operates manually with minimal operator intervention, thanks to an enclosed optical path. The S3500 is engineered for robust performance and includes fixed detectors to ensure precise alignment, with a compact footprint to conserve laboratory space. Furthermore, it supports compliance with FDA 21 CFR Part 11 standards for data integrity, safeguarding your laboratory analytics.
