For most samples wet dispersion represents the ideal method for perfect dispersion. Therefore, the sample material is fed either as a dry powder or also as a suspension into a closed liquid circulation system. The wet dispersion is suitable for almost all materials which do not dissolve in liquid. The advantage compared to the dry dispersion is the higher efficiency and greater flexibility of the dispersion process and the mostly very simple and comfortable handling.

An integrated ultrasonic emitter with up to 100 Watt of ultrasonic power and adjustable dispersion conditions ensures fast and extremely efficient degradation of the agglomerates – precisely adapted to each sample. Due to the integrated water connection, the wet dispersion unit can be automatically cleaned and refilled with new liquid after each measurement. And is quickly ready to be used again.

In order to use the FRITSCH Wet Dispersion Unit you will need the ANALYSETTE 22 NanoTec Measuring Unit (Order No. 22.8000.00).
