The ANALYSETTE 28 ImageSizer is in combination with the corresponding wet dispersion unit ideal for measurement of particle shape and size of suspensions and emulsions with a measuring range of 20 µm – 2.8 mm.

Wet dispersion is particularly suitable for fine particles, poorly flowing, fine-agglomerating or sticky materials, which do not react in water or other liquids.

  • Easy wet measurement

    For perfect dispersion the sample material is feed into a closed liquid circulation system and is pumped with high power through the measuring cell between camera and LED strobe light. The continuously obtained images are the basis for the analysis with a variety of evaluation possibilities.

  • Optimal wet dispersion

    An integrated ultrasonic emitter with up to 100 Watt ultrasonic power and adjustable dispersion conditions, ensure fast and extremely efficient degradation of 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 very quickly ready to be used again. For using the wet dispersion unit, simply insert the wet measuring cell into the measuring unit. If it is not in use, it is securely stored in the dispersion unit.

    FRITSCH Advantage: Powerful pump
    A powerful centrifugal pump with individually adjustable speed ensures optimal transport of even heavy, high-density particles in the wet dispersion unit.

    FRITSCH Advantage: Extremely quiet dispersion
    Through the creation of a separate soundproof ultrasonic chamber, we have drastically reduced the unpleasant noise emission during the dispersion process. Your advantage: the quietest dispersion currently available.

    FRITSCH Advantage: Illuminated dispersion bath
    Ergonomically positioned making it incredibly easy to feed the sample and observe the dispersion process.

    Parameter: Water quality
    Generally, normal tap water is perfectly adequate for wet dispersion. In rare cases, it may be necessary to use distilled water. Just ask us – we will be happy to advise you.

  • Used materials

    The entire dispersion unit consists of high-quality materials. Materials parts in contact with the sample circuit consist of high-quality stainless steel 1.4404 (SS316L), PTFE, BK7 glass, Viton® Extreme, silicone-hoses. So basically the most common organic solvents may be used in the wet dispersion unit. You can download a list of chemicals for the different dispersion units here:
