    Reliable particle size measurement at the push of a button

    Due to its especially wide measuring range of 0.01 – 2100 μm, the NEW ANALYSETTE 22 NanoTec is the ideal, universally applicable Laser Particle Sizer for efficient particle size analysis down into the nano range.

    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.

    With the NEW ANALYSETTE 22 NanoTec the precise measurement of particle sizes becomes a simple matter – even for employees with brief instructions and no prior knowledge, e.g., in merchandise receipt or shipping departments: Start the programme, select a SOP and add the sample. The rest takes place completely automatic.

  • Typical areas of application

    The ANALYSETTE 22 NanoTec is the ideal Laser Particle Sizer for the determination of the particle size distributions of powdery samples, of solids in suspensions and of emulsions. The instrument is perfectly suitable for the utilisation in production and quality control as well as in research and development. 

  • New optical design

    Detecting forward and backward scattering
    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.

    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.

  • Measurement without optical conversion

    Total measuring range without optical conversion

    Especially convenient: In the ANALYSETTE 22 NanoTec the total measuring range of 0.01 – 2100 μm can be detected without converting the optical elements: the distance between the detector and the measuring cell is adjusted automatically. The measuring cell contains the sample particles prepared by the dispersion unit which are irradiated with laser light. By changing the spacing between detector and measuring cell, a different angle range of the scattered light is detected. The particle size distribution is calculated from this data.

    Like every FRITSCH ANALYSETTE 22 Laser Particle Sizer since 1984, the ANALYSETTE 22 NanoTec also employs the FRITSCH-patent of Reverse Fourier design which has been adopted by nearly all manufacturers. It has the advantage that no additional optical elements are required between the measuring cell and detector.

  • Intelligent modular design

    The right dispersion

    The ANALYSETTE 22 NanoTec 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.
    Your advantage: This allows you to buy only what you need for your applications.

    Practical fast-switch-system
    The measuring cells of the ANALYSETTE 22 dispersion modules are located in practical cartridges that can be exchanged with a single motion when switching between wet and dry measurement – without changing any hoses or modifying the instrument!
    Your advantage: fast and easy change of the dispersion method.

    FRITSCH-Tip: Wet dispersion is the ideal method for most of all samples. For easily soluble samples or samples that swell significantly, dry dispersion or the falling chute is the right solution.


  • Fully automatic analysis due to SOPs

    So simple, but also very flexible!

    The ANALYSETTE 22 NanoTec software contains completely predefined Standard Operating Procedures – SOPs for short – for nearly all typical measurement tasks, making operation especially easy. Via a well-arranged input mask, you are completely free and flexible in modifying these SOPs to perfectly suit your measurement requirements.

    By selecting a predefined SOP, for example, dispersion process and duration, measuring frequency and time intervals are set automatically. For flexible adjustment you can also freely select these and many other parameters, save them as a separate SOP and retrieve it at any time. Your advantage: a completely new level of freedom in designing and structuring the entire dispersion and measurement process. And simple, consistent reproducibility of the measurement sequence.

  • Perfect evaluation - MaS control

    For the control, recording and perfect evaluation of your measuring results your ANALYSETTE 22 NanoTec 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. Graphics as well as all measuring parameters, statistical values or selected measured values can be incorporated in a report. Your advantage: simple, secure, flexible.
