Bettersizer 2600

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.

3）WET DISPERSION
Laser diffraction method conforming to ISO 13320
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. Meanwhile, particle analyzer price is affordable.

4）DRY DISPERSION
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. Our particle sizer price is affordable, welcome to consult.
