The ANALYSETTE 28 ImageSizer from Fritsch is the ideal particle sizer for fast analysis of particle shape and size of dry, free-flowing materials.
The dynamic image analysis offers an extra wide measuring range of 20 μm - 20 mm, individually adjustable. The measuring time, depending on the sample quantity, is under 5 minutes with immediate results. This makes the ANALYSETTE 28 ImageSizer the perfect measuring instrument for the easy quality control, as well as for research and for laboratory tasks - and it is the fast alternative to sieving.
For measurement, the sample material is filled into the funnel and conveyed to the falling chute via the automatically controlled feeder, which its U-shaped cross section ensures a good material feed. There, the sample falls through the measuring chamber between the camera and LED strobe light into an easy to clean sample collecting vessel. The images recorded continuously during this process offer a variety of evaluation possibilities. And the sample remains undamaged and completely intact throughout the entire analysis process.
For exact reproducible measurements, the position of the feeder and the funnel height can be adjusted via a scale and stored as information in a SOP. The ideal feed rate, precisely adapted to the sample, can also be stored in the SOP. The particle concentration is determined and controlled by the software. Your advantage: always the optimal number of particles per image for a reliable and significant analysis.
Thanks to the bi-telecentric lenses, the ANALYSETTE 28 ImageSizer guarantees always the same reproduction scale of each individual particle wherever it is located in the measurement volume. Compared to conventional lenses, there is also a greater depth of field and less image field distortion. Your advantage: a more accurate measurement through a higher magnification consistency.
The duration of the measurement can be varied depending on the desired number of images (up to 75 images/sec.) or on the number of measured particles.
The evaluation of the measuring results is uniquely simple with the ANALYSETTE 28 ImageSizer. The modern ImageSizing-Software ISS displays each recorded particle clearly as a data point. Individual selected particles can be immediately analysed and evaluated and all available sizes and shape parameters are automatically displayed.
To get a quick overview of the typical particle shape of the analysed sample, view and evaluate all the images in a gallery which is integrated directly into the software for easy use.
