Automatic Dispersing System for Particle Analysis in Suspensions and Emulsions
Apr 22 2021
Fritsch’s proven particle sizer ANALYSETTE 28 ImageSizer in combination with the new automatic and powerful wet dispersion is especially suitable for fine particles, poorly free-flowing, fine-agglomerating or sticky materials that do not react in water or other liquids.
For perfect dispersion, the sample material is placed in a closed liquid circuit and pumped through the measuring cell between the camera and the LED stroboscope light at high pump power. The continuously recorded images form the basis for the analysis with a variety of evaluation options.
For wet measurement, choose from 3 different bi-telecentric objectives for optimum adaptation of the total measuring range from 5 μm to 3 mm to your measuring task. In combination with the powerful industrial camera, they guarantee the highest accuracy of the imaging of each individual particle always at the same imaging scale and the highest shape accuracy with the greatest possible depth of field.
The fully automatic wet dispersion unit has no valves and moving seals in the sample circuit for emptying the system. This makes it significantly more robust and virtually wear-free. There are no hard-to-clean dead spaces in which dirt can become permanently lodged. A single rinse is all it takes and it is ready for use again.
For samples that tend to agglomerate, a powerful ultrasonic box can Be connected to the wet dispersion unit. It enables an even finer adjustment of the wet dispersion to the respective sample.
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. With SOP’s for easy operation, a completely free programmable dispersion process and automatic cleaning, fast and reproducible measuring results are ensured.
For measurement results, the modern evaluation software ISS clearly shows each captured particle as a data point in the immediately available Fritsch Cloud as well as in the Fritsch Gallery. You can analyse and evaluate individual selected particles at any time with all available size and shape parameters or get an overview of the typical particle shape of the examined sample.
