The NEW Universal Cutting Mills from FRITSCH are ideal for size-reduction for a wide range of different materials due to variable adjustment of the rotational speed of the rotor, various knife geometries, replaceable blades, practical sieve cassettes and that with an unmatched ease of cleaning.

Variable 300-3000 rpm for fine comminution
The high-speed Universal Cutting Mill PULVERISETTE 19 comminutes up to 60 l/h of soft to medium-hard sample materials and fibrous materials at a torque of up to 30 Nm with reliable reproducible results. The great advantage: The variable rotational speed adjustment in increments of ten between 300 and 3000 rpm enables fine tuning of the comminution process for each sample within a very wide range of applications.

Variable 50-700 rpm for powerful comminution
The low-speed Universal Cutting Mill PULVERISETTE 19 with variable rotational speed adjustment between 50-700 rpm and a torque of up to 67 Nm enables due to the combination of low cutting rate and extreme cutting forces a very powerful comminution of hard, tough-elastic samples and small sample quantities. At the same time, it is the ideal solution for all cases where e.g. thermal damage, the loss of highly volatile substances, or an excessively high fine share need to be avoided.

Especially for analytical sector, food and pharmaceutical industry
The Universal Cutting Mill PULVERISETTE 19 is also available in both variable rotational speed versions in a corrosion-resistant stainless steel 316L version. All materials have an increased resistance to alkalis and acids and are conform to the guidelines of the food and pharmaceutical industry.

Optimal sample exhaustion: FRITSCH Cyclone separators
Clean, convenient, cool: Combine your FRITSCH Universal Cutting Mills PULVERISETTE 19 with a FRITSCH Cyclone separator for sample exhaustion and an exhaust system which can be ordered along. The strong airflow ensures simple feeding, increases throughput, reduces the thermal load of the samples and enables the use of finer sieve cassettes to achieve a higher final fineness – even for materials, which are otherwise difficult to comminute finely. The result: an especially fast and efficient comminution.

Choose according to your needs:

FRITSCH high-performance Cyclone separator
The FRITSCH high-performance Cyclone separator completely made of stainless steel 304 is particularly indispensable in the analytical sector and in the food and pharmaceutical industries, and for the processing of heterogeneous mixtures of material, e.g. in the cement industry. Due to its high surface quality, it offers enhanced resistance to corrosive media such as alkalis and acids and is especially easy to clean with a wide range of possible cleaning agents, without leaving any residues. In addition, it can be completely dismantled, fully emptied, flooded and sterilised, and thus offers reliable protection against cross-contamination.
Especially convenient: The comminuted sample is drawn directly into the screwed-on sample glass or in a larger collecting vessel of up 60 litres, in which it can also be transported and stored.

FRITSCH small volume Cyclone separator
Especially for exhaustion of small sample quantities, we designed the compact FRITSCH small volume Cyclone separator. It is made of plastic, can be dismantled completely and cleaned in a dishwasher for reliably preventing contaminations. The comminuted sample is collected in a screwed-on sample glass of 250 or 500 ml volume.

Clean Design for unmatched ease of cleaning
Available only from FRITSCH: For residue-free cleaning all grinding parts of our Cutting Mills can be removed within seconds without tools – unbeatable fast, simple and efficient.

With the new FRITSCH Laser Particle Sizer ANALYSETTE 22 NanoTec particle measurement becomes a simple matter, for professionals as well as for any employee – in production and quality control or in research and development. No prior knowledge is required. Just start the programme, select a SOP and add the sample – the rest takes place completely automatic. Fast. Reliable. Efficient.

Your advantage: extremely simple operation, short analysis times and consistently reproducible and reliable results. And a convincing combination of price and performance.

New optical design

Measurement design for the lower particle size range

The very large measuring range from 0.01 µm to 2100 µm 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. Especially convenient: The total measuring range of 0.01 – 2100 µm in the ANALYSETTE 22 NanoTec can be detected without converting the optical elements.

Intelligent modular design

Always the right dispersion module: The measuring cell is simply switched to change the 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.

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.

Perfect fully automatic evaluation

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. Your advantage: Simple, secure, flexible.

State-of-the-art, simple and fast evaluation via FRITSCH Cloud and Gallery

The evaluation of the measuring results is uniquely simple with the ANALYSETTE 28 ImageSizer. The evaluation software ISS displays each recorded particle clearly as a data point in the immediately available FRITSCH Cloud as well as in the FRITSCH Gallery. You freely choose which statement is of interest to you: for example the Sphericity in regards to the Minimum Feret Diameter, the aspect ratio, applied on the porosity, or the convexity as a function of the particle Cross Section. Or display the particle size distribution as a cumulative curve, as a bar chart or in a table form.

The FRITSCH Cloud: Each particle can be clicked individually

The state-of-the-art of uncomplicated evaluation: For fast single image viewing, each individual particle can be opened directly with a mouse click from the clearly arranged FRITSCH Cloud. The really important information for you about the morphology will be shown by the position of the data point in the Cloud. Without time-consuming search, you can immediately analyse, evaluate and delete individual selected particles. All available size and shape parameters are automatically displayed.
