Particle Sizer for Dry and Wet Measurement

The Analysette 28 ImageSizer from Fritsch provides analysis of particle shape and size for dry measurement of powders and bulk solids and wet measurement of suspensions and emulsions. The device delivers multiple shape parameters and evaluation possibilities for particle size. According to the company, measurement results are available immediately and measuring time is under five minutes depending on the sample quantity. 

For wet measurement, the device is used in combination with a complementary wet dispersion unit. Features include a measuring range of 20 μm–2.8 mm, freely adjustable ultrasonic power for deagglomeration, quiet dispersion with strong pumping power, automatic rinsing cycle, no dead space in measuring and rinsing circulation system, and fast and consistent cleaning. The company states that benzine, alcohol, and various organic solvents can also be used as suspension liquid.

For dry measurement, the particle sizer provides fast analysis of particle shape and size of dry, free-flowing materials. Features include a measuring range of 20 μm–20 mm, three available telecentriclenses, up to 75 images per second, preserved agglomerates, practical clean design of the measuring chamber, and optimal number of particles because of automatic adjustment of the feeder.

The evaluation software used for measuring results displays each recorded particle as a data point in the company’s Cloud, which enables each particle to be clicked individually, and the Gallery, which provides an overview of the typical particle shape of the analyzedsample and allows users to view and evaluate all images. Individual particle images can be directly selected for single image analysis.
