Dispersion units
Bettersizer 2600 Plus family
Wet dispersion units
Consistent dispersion workflow for reliable results
Image Credit: Bettersize Instruments
In order to establish a stable suspension, wet dispersion introduces the sample to a selected liquid medium, such as water or an appropriate organic solvent. Dispersion conditions are maintained by a controlled process, which is often defined by automated Standard Operating Procedures (SOPs).
While integrated ultrasonic treatment breaks down agglomerates and helps release trapped air, continuous circulation and stirring encourage homogeneity. After passing through the optical measuring zone, the suspension is recirculated for reliable examination. The addition of automated surfactant improves wetting and suspension stability even more, reducing re-agglomeration and enabling consistent, operator-independent outcomes.
Core functions across wet dispersion units
Surfactant addition: Enhance wetting and maintain suspension stability
Ultrasonic energy: Disperse particles and aid in the elimination of trapped air
Stirring and circulation: Guarantee consistency and reduce settling

Dry dispersion units
Controlled deagglomeration for repeatable results
Image Credit: Bettersize Instruments
Dry dispersion involves the introduction of powder samples into the system using gases as the medium. The sample is transported to the disperser via controlled vibrations.
Within the disperser, particles are propelled by a meticulously regulated high-pressure gas stream that passes through a Venturi device. Shear forces, collisions between particles, and impacts with the walls contribute to the disintegration of agglomerates prior to measurement.
The stream of dispersed particles moves through the laser diffraction measurement area for analysis, and is efficiently evacuated and collected by a vacuum unit.
Shear forces: High-velocity airflow effectively separates loosely bound agglomerates during the processes of acceleration and transport.
Inter-particle collisions: Controlled flow collisions facilitate deagglomeration and enhance dispersion stability.
Particle-wall impacts: Impacts occurring within the inlet pathway improve the breakup of agglomerates prior to measurement.
