  Chemistry and Biotechnology - Fritsch GmbH - ANALYSETTE 22



Website: http://www.fritsch-milling.com/
SIMPLE / FLEXIBLE / RELIABLE
ANALYSETTE 22
Quality and technology from Germany
SIMPLE / FLEXIBLE / RELIABLE
Static light scattering – perfect for particle sizing up to 2100 µm!
Due to its especially wide measuring range of 0.01 – 2100 µm, the ANALYSETTE 22 NanoTec is the ideal, universally applicable Laser Particle Sizer for efficient particle size analysis down into the nano range – in production and quality control as well as in research and development. Benefit from its decisive advantages: extremely simple operation, short analysis times and consistently reproducible and reliable results. And a convincing combination of price and performance.
ANALYSETTE22
FRITSCH - PLUS
icon Intelligent modular design
Each ANALYSETTE 22 consists of a compact measuring unit that can be quickly and easily combined with various dispersion units for dry respectively wet measurements. This allows you to buy only what you need for your applications.
icon Practical fast-switch-system
Quickly switch between dispersion units by simply changing the cartridge containing the measuring cell.
icon Short measuring time
The ANALYSETTE 22 completes most measurements in less than a minute. The instrument is then immediately ready to be used again.
icon Fully automatic analysis
With clearly organized results visible directly on the screen. Of course, you can also print out or save a report customized to your needs.

ANALYSETTE 22 NanoTec

ANALYSETTE22
icon Measurement even of nano particles in an extremely wide measuring range of 0.01 – 2100 μm
icon Fast, automatic particle size analysis
icon Simple measurement with short measuring times
icon Especially high measurement precision due to the analysis of 110 channels
icon Consistent reproducibility – reliable comparability
icon User-friendly operation
icon Quick change between wet and dry measurement
icon Fast and simple cleaning
The very large measuring range of the ANALYSETTE 22 NanoTec results from 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. The result: perfect measurements with outstanding reliability, meaningful comparability and consistent reproducibility.

FRITSCH-Plus

Highest measurement precision with all detectors
The elegant FRITSCH measuring solution: The ANALYSETTE 22 NanoTec always uses all measuring channels, which are detected in 41 microseconds (24 kHz). By combining the various measurement positions, up to 110 effective measuring channels are detected in the measurement. Your advantage: a particularly high resolution and sensitivity.
