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 5 µm – 3 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.
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.
A powerful centrifugal pump with individually adjustable speed ensures optimal transport of even heavy, high density particles in the wet dispersion unit – enabling fast, uniform distribution of the sample material in the entire circuit. SOP’s for easy operation, the completely free programmable dispersion process, the automatic cleaning ensure fast and reproducible measuring results.
NEW: wet dispersion unit available in 2 versions
The wet dispersion unit for automatic dispersion is suitable for many suspension liquids, like for example water, alcohol and many organic solvents. If you are working with extremely aggressive chemical dispersion liquids, the wet dispersion unit EXTENDED for extreme chemical resistance is the right choice. A list providing an overview of chemicals can be downloaded here.
NEW: 3 lenses to select
Choose from 3 different telecentric lenses for wet measurement. By choosing the suitable lens, the measuring range can be optimally adapted to the measuring task. And if your application changes, all lenses can be retrofitted and easily replaced at any time.
The bi-telecentric lenses of the integrated camera guarantee the highest precision of the image of each individual particle always at the same reproduction scale and thus the highest shape accuracy with the greatest possible depth of field.
NEW: Wet dispersion system without dead space
The first fully automatic wet dispersion unit operating completely without valves and moveable seals in the sample circulation system and for emptying the system. That makes it significantly more robust and virtually wear-free. And no difficult to clean dead spaces occur in which soiling can get deposited permanently. A single rinse is sufficient and it is ready to be used again. Without soiling. Without wear.
Separate ultrasonic box
If you frequently measure sample material that tends to agglomerate, you can additionally connect a powerful ultrasonic box to the wet dispersion unit. It enables an even finer adjustment of the wet dispersion to the respective sample material.
All parts in the sample circulation, which come into contact with the dispersion medium are made of high-quality stainless steel 316L, PTFE, FFKM, FEP, silicone, POM, BK7, ETP-S, (hoses made of silicon, seals mad of FFKM and ETP-S) and are suitable for use with alcohol and many organic solvents as suspension liquids.

For wet measurement, please order wet dispersion unit, lenses according to the desired measuring range and if required ultrasonic box separately.
