Laser Particle Size Analyzer (Dry & Wet Dispersions)
The integrated and robust laser particle size analyzer, Bettersizer 2600, can deliver reliable particle size measurement results from submicron to millimeter. Driven by the innovative optical system and Standard Operation Procedure (SOP), the Bettersizer 2600 wet and dry particle size analyzer strikes a harmonious balance between high-functionality, easy operation, low maintenance, and cost-effectiveness.

1）Fourier and Reverse Fourier optical system
Bettersizer 2600 particle size tester is characterized in particular by its unique and innovative optical bench design: the light focused on the detectors through the lens is scattered by particles and detected in both forward and lateral directions (Inverse Fourier structure). In contrast to conventional laser diffraction devices, the backscattered light passes through the lens a second time. In addition, the cuvette is positioned at an angle of 35° to the incoming laser light.
This smart setup allows, on the one hand, the detection of scattered light in a very wide angular range from 0.016° to 165°. On the other hand, in contrast to a pure Inverse Fourier structure, the particles do not have to lie in one plane – the simultaneous exact measurement of small and large particles is therefore achieved.

In a wet measurement, the particles are dispersed in a liquid medium in the dispersing module, additional dispersion may be performed by an ultrasonic disperser.
Various external modules are also available to achieve this purpose:
BT-802 – is a fully automatic standard dispersing module with integrated ultrasound and centrifugal pump for sample circulation with a volume of 600 ml. It is suitable for large sample sizes for materials that can be dispersed in water or alcohol.
BT-800N – is a dispersing module with medium volume (approx. 250ml) with ultrasound and centrifugal pump; suitable for non-polar solvents such as heptane, toluene and oil.
Dry dispersion is used when dry powders or granules are to be measured without the use of solvent. During sample preparation, the sample is pre-dispersed by a vibrating transmission channel, it falls into a channel and is transported by compressed air (venturi nozzle) through to the horizontal measuring cell. Dispersion is carried out by particle collisions with the wall of the container and particleparticle shear.
Switching dispersion modules is easy. Simply remove one module and replace it using its handle. Dry dispersion is also possible with a variety of external modules:
BT-902 – this is an automatic standard dry dispersing module with a particle conveying channel with adjustable conveying rate; adjustable dispersion pressure (up to max. 5 bar) enable it to be suitable for all powders and granules whether they be cohesive or free flowing.
BT-903 – is an automatic dry dispersing module for small sample sizes of powders; ideal for powders in research or pharmaceutical applications. 20 mg to 1 g sample sizes.
