New laser particle sizer

FRITSCH has released its new Laser Particle Sizer ANALYSETTE 22 NanoTec for particle measurement.


The measuring range from 0.01 - 2100 µm of the ANALYSETTE 22 NanoTec is a result of the combination of two lasers with two different measuring cell detector spacings: large particles are detected using an infrared laser with a large distance to the measuring cell, for small particles a green laser with a small distance to the cell is used, which permits the detection of the forward scattered light up to a scattering angle of 65°. The measurement of smallest particles down into the nano range is performed by the green laser light for backward scattering. Specially arranged detectors ensure this. Especially convenient: The total measuring range of 0.01 - 2100 µm in the particle sizer can be detected without converting the optical elements.

Modular design

The laser particle sizer consists of a compact measuring unit that can be quickly and easily combined with different dispersion units for dry or wet measurement. Select the wet dispersion unit for wet measurements of solids and suspensions. For wet dispersion of very small quantities, the automatic small volume wet dispersion unit SVA with illuminated dispersion bath and the compact manual small volume wet dispersion unit SVM are available. The practical, fully automatic AutoSampler makes it easy to perform a series of measurements with the wet dispersion unit. For dry measurements of not too fine, free flowing materials use the dry dispersion unit with efficient degradation of agglomerates. For dry measurement of agglomerates or free flowing materials, choose the falling chute.

Fully automatic evaluation

For the control, recording and evaluation of your measuring results, the laser particle sizer is delivered with a computer on which the FRITSCH MaS control software is already fully installed. The software MaS control is easy to learn and guides you through the entire measurement process in a largely self-explanatory manner. In addition to integrated standard reports, the freely editable report generator allows you to organise your measurement reports exactly according to your needs.
