For the first time - determination of particle size distributions and particle shape recognition in a single process

In many sectors of industry, knowledge of the particle size distribution and particle shape of pulverised material or suspensions is a vital aspect of quality control. Measurement of these characteristics also play a noteworthy role in production monitoring (e.g. of crushing plants).

FRITSCH with their vast experience in the particle sizing field is now able to offer the FRITSCH "analysette 22" Laser-Particle-Sizer in different versions and with complete new features.

Here a glance of the different models:

Laser-Particle-Sizer "analysette 22" NanoTec

For fast automatic measurement of particle size distributions of suspensions, emulsions and dry powders.

Measuring range:

for suspensions + emulsions:0.01 - 1000 microns

for dry powders:0.1 - 1000 microns

With the intelligent interpretation and further development of the FRITSCH patent for "Inverse Fourier Optics (convergent laser beam)", the NEW "analysette 22" NanoTec achieves a measuring range down to the nanometer range.

The revolutionary design along with the new optical, mechanical and electronic components and a new, modern, flexible analysis software makes the "analysette 22" to an analysis instrument, which is on the most modern state of the art.

As a unique feature, the NanoTec-version offers optionally the output of the elongation ratio for specific particle sizes and is therefore together with the MicroTec-Version of FRITSCH the only instrument in the world that makes it possible to have information on the particle shape on the basis of light scattering.

Laser-Particle-Sizer "analysette 22" MicroTec

The "analysette 22" MicroTec is the measuring instrument for samples in the micron and sub-micron range. The reduced optical bench allows a very compact and inexpensive design.

The MicroTec is the "little" brother of the NanoTec. All hardware and software components are identical with those of the "analysette 22" NanoTec except for the nano expansion. The measuring range is from 0.1 to 600 µm for the measurement of particle size distributions of suspensions and emulsions as well as for dry powders.

Laser-Particle-Sizer "analysette 22" COMPACT

With the new COMPACT-model of the "analysette 22", FRITSCH is now providing those users the possibility to make use of the high tech laser technology, which had so far no sufficient budget available. The COMPACT-model can measure particle size distributions of any suspensions and emulsions as well as of dry powders in the range of 0.3 to 300 microns - fast, rationally and efficiently.

All models of the "analysette 22" Laser-Particle-Sizer family use the laser diffraction technology with patented convergent laser beam and are therefore the only instruments in which the measuring cell is moved along the optical axis to adjust the measuring range without the need to change the lens. The sample is therefore always measured with the greatest dynamic and optimal conditions.

FRITSCH offers due to its equipment varieties for each special use and application a particle size measuring instrument with the most modern laser technology and this with an unbeatable price-to-performance ratio.
