Laser Particle Size Analyzer (Dry & Wet Dispersions)

The Bettersizer 2600 utilizes this laser diffraction technology. There are 92 photoelectric detectors to convert light signals from the scattering spectrum to electrical signals, which are transmitted into an intelligent software. By implementing the Mie scattering theory to the data and performing mathematical conversion, the complete particle size distribution can be derived.

Application Notes

Overview

Features

1)FOURIER AND REVERSE FOURIER OPTICAL SYSTEM

The Bettersizer 2600 is superior in the combination of Fourier and inverse Fourier design. This smart design allows, on the one hand, the detection of stray light in a very wide angular range from 0.016° to 165°. On the other hand, in contrast to the inverse Fourier design, the particles do not have to lie on one plane – the simultaneously accurate measurement of small and large particles is therefore achieved.

Features of combination of Fourier and inverse Fourier design 

Spherical detector array: Forward, lateral and backward detectors in 92 pieces in total; 

Super large Fourier lens; 

Small footprint: Compact design to save space

2)INTUITIVE AND POWERFUL SOFTWARE

Intuitive operation and orderly user interface 

Real-time mode for determining the optimal measurement conditions 

Fully automatic measurement routine 

Automatic cleaning routine 

Automatic data backup and highly customizable reports 

Direct conversion according to Fraunhofer and Mie evaluation models 

Switch between wet and dry dispersion modules with one click

3)WET DISPERSION

BT-802 is designed for particle size measurement with water as the medium. 

BT-802 is made up of ABS shell. The components of it include centrifugal pump, peristaltic pump, ultrasonic disperser, pinch valve, control circuit, etc. The stirring speed is adjustable from 500 - 2500 rpm. Built-in ultrasonic system (50 W) ensures stable dispersion of samples.

BT-80N is designed for particle size measurements with organic solvents as the media. BT-80N is suitable for common organic solvents, for example:

BT-80N is made up of stainlesssteel shell. The components of it include centrifugal pump, ultrasonic disperser, PTFE pipeline, sintered-quartz sample cell, control circuit, etc.

Wet Small Volume Dispersion Module is designed for valuable or small-volume sample measurements, where the medium is solvent or water. The module consists of ABS shell, stirring motor, cuvette (8 ml), stirrer, etc. 

Maximum volume in 8 mL with samples mass in 0.005 - 0.1 g. 

Suitable for samples dispersed in water or organic phase.

4)DRY DISPERSION 

BT-902 is suitable for dry powders particle size measurements. The gas used can be compressed air, nitrogen or other noble is.

BT-902 is made up of electromagnetic vibration feeder, venturi pipe, gas circuit, electric circuit, pressure sensor, etc.

BT-903 is designed for particle size measurements of valuable and small amount dry powders with a minimum samples volume of 20 mg.

BT-903 is composed of venturi pipe, gas circuit, electric circuit, samples tube, etc.
