Bettersizer S3 Plus Laser Diffraction Particle Size and Shape Analyzer & BT-803 Wet Dispersion Unit
MSE Supplies is an authorized distributor of Bettersize Instruments. The product is sold for US customers only.
Introduction
The Bettersizer S3 Plus is a combined laser diffraction and dynamic imaging particle analyzer, designed to operate with the BT-803 wet dispersion system. Its patented DLOI (Dual Lenses & Oblique Incidence) laser diffraction optical system is equipped with a 10 mW, 532 nm laser and 96 detectors, covering a scattering angle range of 0.02°–165° and featuring an auto-alignment mechanism. The dynamic imaging optical system incorporates dual-magnification cameras (0.5× and 10×) with a 120 fps imaging rate, a white LED surface source, and a blue LED point source, capable of capturing up to 10,000 particle images in 60 seconds and providing 32 particle size and shape parameters—including aspect ratio, circularity, roundness, convexity, and more. The instrument offers a particle size measurement range of 0.01–3500 μm, with testing accuracy and repeatability better than 0.5%, in compliance with ISO 13320 and USP <429>; it also provides a particle shape measurement range of 2–3500 μm, in compliance with ISO 13322. The intelligent software supports SOP workflows, editable reports, sample refractive index calculation, sample ratio calculations, and 21 CFR Part 11 compliance management.
The BT-803 automatic dispersion module has 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 BT-803 includes 4 sample cells.
Key Features
1. Patented DLOI (Dual Lenses Oblique Incidence) System: Laser Diffraction
Laser diffraction technology for routine particle size analysis remains the method of choice across various industrial sectors. The Bettersizer S3 Plus applies the patented DLOI system, which is designed based on the Fourier structure to guarantee the accurate measurement of ultrafine particles from 0.01 μm.
Features and Benefits:
- Measures ultrafine particles accurately with the large angular range (0.02 - 165°) with 96 detectors
- Robust optical system with superior resolution using the dual lenses design
- Single short-wave laser system (532 nm) delivers a continuous scattering spectrum with a consistent wavelength
- Zero stabilization and preheating time needed with a solid-state light source
2. Dual-Camera System: Dynamic Image Analysis
Dynamic image analysis can strengthen your understanding of materials with the comprehensive shape or morphological information that is independent of laser diffraction. Individual particles with specific geometric properties such as agglomerates, crushed particles, and foreign particles can be effectively tracked through the dual-camera system.
Features and Benefits:
- 0.5x and 10x cameras - photograph an extremely wide size range of particles
- High-speed strobe lights - capture up to 10,000 particle images in 60 seconds, offering authentic shape results
- Suitable for measuring heterogeneous samples with unknown optical properties
3. Groundbreaking Combination: Laser Diffraction with Dynamic Image Analysis
The Bettersizer S3 Plus integrates laser diffraction and dynamic image analysis into one instrument to simultaneously characterize particle size, size distribution, and particle shape over a wide dynamic range. Working in tandem, users can gain a deeper understanding of material behavior to fasten the troubleshooting process and method development process.
Features and Benefits:
- DLOI System - precisely measures ultrafine particles down to 0.01 μm
- Dual-camera Imaging System - efficiently detects oversized particles up to 3,500 μm
- 2-in-1 System - simultaneously obtains particle size and shape results
- Fast time-to-result - rapidly generates results in 10 seconds
