Bettersizer ST

Your One-Stop QC Tool

The Bettersizer ST is an automated laser diffraction particle size analyzer designed for industrial quality control. Its patented DLOS (Dual Lens Optical System) guarantees the instrument to provide consistent and reliable particle size distribution results. The SOP (Standard Operating Procedure) and automated analysis procedures are designed to help you save valuable time for quality inspection. 

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.

Standard Operating Procedure (SOP) 

SOP is an easy solution for standardized and automatic testing. It ensures the measurement results are operator- independent, objective and reliable.

Innovative DlOS Technology 

The DLOS (Dual Lens Optical System) is a patented optical system designed by Bettersize Instruments. In DLOS, one single laser source and two large Fourier lenses are utilized, and the combination of wide-angle forward, lateral and backward photodetectors allows consistent and accurate results with a measurement range from 0.1 to 1000 μm.

Features

• High resolution and accuracy ensured by two large Fourier lenses
• Expands measurement range with 86 high-speed photodetectors
• Compact design prevents using folding optics
• Continuous incident light with consistent wavelength provided by one single laser source

 

Advantages

• Measurement range: 0.1 – 1000 μm
• Avoid misalignment

 The compact design of DLOS removes folding optics that are susceptible to misalignment

• More reliable results

 Only one laser source is utilized to provide a continuous scattering spectrum with consistent wavelength

• Cost-efficient

 Reliable results without a second laser source leads to cost efficiency
