Bettersizer ST Automated Wet Dispersion Laser Diffraction Particle Size Analyzer

Bettersizer ST Automated Wet Dispersion Laser Diffraction Particle Size Analyzer

MSE Supplies is an authorized distributor of Bettersize Instruments. The product is sold for US customers only.

Introduction

The Bettersizer ST is based on the principle of laser diffraction and provides both Mie and Fraunhofer theoretical models. Its patented DLOI (Dual Lenses & Oblique Incidence) laser diffraction optical system is equipped with a 10 mW, 635 nm laser and 86 detectors, covering a scattering angle range of 0.031°–159° and featuring an auto-alignment mechanism.The instrument intergrate the wet disperision system, with a 600 mL capacity, features circulation dispersion, adjustable stirring speed from 300 to 2500 rpm, and ultrasonic power up to 50 W. It supports fully automatic liquid intake, sample dispersion, and cleaning operations. The instrument offers a particle size measurement range of 0.1–1000 μm, with testing accuracy and repeatability better than 1%, in compliance with ISO 13320. The intelligent software supports SOP workflows, editable reports, and 21 CFR Part 11 compliance management. It includes 3 sample cells.

Key Features

1. Excellent Accuracy

♦ Accuracy verification of standards

• Duke standard samples were measured separately by the Bettersizer ST laser particle sizer, showing the distribution peak in the correct position and narrow distribution with high accuracy.

• The red line is the nominal size range of standards ± 1.0%, and the black dots are the measured sizes. As shown in the figure, the measurement accuracy of Bettersizer ST laser particle sizer for standards is within 1%.
  

2. Outstanding Repeatability

Exceptional repeatability provided by Bettersizer ST laser particle sizer ensures the reliability of the results. Rapid measurements with consistent and reliable results can ease your workload on quality control.

♦ Excellent repeatability from
