Intelligent automatic laser particle size analyzer with automatic sample dispersion and recirculation for fast, reliable routine particle size measurement in production and QC laboratories.
The BT-9300ST is an intelligent automatic laser particle size analyzer featuring automatic sample loading, ultrasonic dispersion, and recirculation. Designed for routine, high-throughput particle size measurement in production QC labs, it delivers fast, accurate results with minimal operator intervention.
The BT-9300ST is engineered for reliability and ease of use in routine production QC environments. Its fully automatic recirculating sample cell continuously circulates the sample dispersion through the measurement zone while the built-in 40 W adjustable ultrasonic bath maintains dispersion without manual intervention.
The laser diffraction measurement principle provides a fast, robust particle size distribution based on the Mie scattering model. With a measurement time of just 60 seconds per sample and reproducibility better than 1% RSD on D50, the BT-9300ST delivers the speed and consistency required for high-throughput production QC.
The Windows-based software includes customizable report templates, batch measurement sequences, and statistical analysis tools for trend monitoring and SPC integration.
