WET DISPERSION.  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 including:

  • 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.  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.
