Introduction of Bettersizer Series Particle Size Analyzer
Bettersizer Series particle size analyzers include four models - Bettersizer S3 Plus laser particle size analyzer ( used for the particle size analysis and particle shape analysis), Bettersizer S3 laser particle size analyzer( used for the particle size analysis and particle shape analysis), Bettersizer 2600 dry and wet dispersion particle size analyzer by laser diffraction (used for the analysis of particle size for different powders by wet dispersion and dry dispersion), and Bettersizer ST laser particle size analyzer (rugged and compact design used for the analysis of particle size by wet dispersion).
BETTERSIZER S3 PLUS - COMPLETE PARTICLE SIZE AND PARTICLE SHAPE ANALYSIS BY ONE DEVICE
The Bettersizer S3 Plus
particle size analyzer combines the advantages of 2 measurement methods, "
laser diffraction" and "dynamic image analysis". The laser diffraction method is based on Mie scattering theory. It offers a comprehensive and precise characterization of particle size from nanometers to millimeters. The live view of the CCD cameras before and during the measurement allows the user to evaluate the dispersion state of the sample and visually assess the measurement result. All particles above 2 μm are photographed and evaluated as the request of the user.
This system has the capability to measure shape by “Dynamic image analysis” over the 2 to 3500μm size range.
BETTERSIZER S3 - STATE-OF-THE-ART LASER PARTICLE SIZE ANALYZER
Bettersizer S3 represents the leading particle size analysis technology for wet dispersion solutions. It is based on Mie scattering theory. The measuring range from 0.01 to 3500μm meets the most stringent requirements of fundamental research, product development and process control applications. The easy to use SOP and automatic circulation and dispersion system ease workload and improve the user experience. A new capability of this system is its ability to measure shape by "Dynamic image analysis" over the 100 to 3500μm size range.
BETTERSIZER 2600 - PARTICLE SIZE ANALYZER BY LASER DIFFRACTION WITH WET AND DRY DISPERSION
The Bettersizer 2600 is a modern particle size analyzer that works under the principles of laser diffraction methods and conforms to the ISO 13320 standard.
The intelligent combination of the two traditional methods – Fourier and Reverse Fourier – accurately measures fine and coarse particles even over a wide particle size distribution.
For dispersion, Bettersizer 2600 offers normal or small volume wet and dry modules. The smart modular design achieves wet to dry changeover in a matter of seconds.
WET AND DRY DISPERSION SYSTEM:
In wet measurement, the particles are dispersed in a liquid medium in the dispersing module. If necessary, additional dispersion can be achieved by the ultrasonic disperser.
Dry dispersion is used when dry powders or granules are to be measured in their natural state thus not requiring any use of solvent. During sample preparation, the sample is pre-dispersed by a vibrating transmission channel, falls into a channel and is conveyed by compressed air (venturi nozzle) through the closed, horizontal measuring cell. Dispersion is carried out by collision of the particles on the wall of container and by particle/particle shear. The change between the dispersing modules is rapid and only requires one step.
BETTERSIZER ST - RUGGED AND COMPACT LASER PARTICLE SIZE ANALYZER
The Bettersizer ST includes the patented DLOS (Dual Lens Optical System) which allows the ST to measure a wide particle size range. This technology increases system reliability and reduces cost by fully utilizing the capabilities of a single laser diode. The DLOS provides a compact design without resorting to folding optics that are susceptible to misalignment caused by vibrations often present in most industrial laboratories.
The ST incorporates 86 detectors to produce high resolution data from 0.1 to 1000 μm.
