  • OVERVIEW

    Variable 50–700 rpm for powerful comminution

    Due to the variable rotational speed adjustment in increments of ten between 50 and 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. The low-speed PULVERISETTE 19 comminutes hard, tough-elastic samples with a maximum feed size of 70 x 80 mm and a throughput of 60 l/h. 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. One special advantage: Straw, films and similar materials can be fed in up to their full length without additional preparation. And the PULVERISETTE 19 is also ideal for RoHS tests.

    FRITSCH also offers a high-speed Universal Cutting Mill with 300-3000 rpm for a fine comminution

  • WORKING PRINCIPLE

    Unique grinding chamber geometry

    The sample material is comminuted according to the cutting principle of scissors between the cutting edges of the rotor and the fixed knives in the grinding chamber until the desired final fineness is achieved. Unique grinding chamber geometry: The grinding chamber is designed with minimal dead space and progressive cutting geometry between rotor and fixed knives. The sample material is continuously moved during comminution and cannot settle anywhere. In conjunctions with the special air flow, this is the basis for swift, blockage-free operation and fast cleaning without residue.

    Running stabilisation due to flywheel mass

    The Universal Cutting Mill PULVERISETTE 19 is equipped with a flywheel mass to stabilize the drive torque. This ensures stable operation even for extreme short-term load, as well as an optimal comminution result.

  • SIMPLE CLEANING

    Optimised Clean Design for unmatched easy cleaning!

    While you are still tightening the screws on other mills, your FRITSCH Cutting Mill is already clean. The instrument hood now consists completely of easy-to-clean stainless steel and the seals of the grinding chamber were completely revised. With just a few simple motions the entire grinding chamber can be opened and rotor and sieve cassette can be removed without tools. The housing and lid can be lifted back completely, and the grinding chamber lid can be completely removed from the hinges.

    The result: a completely open, empty grinding chamber with minimised dead space and smooth interior walls for quick and easy cleaning and reliable protection against cross-contamination.

  • COLD COMMINUTION - EMBRITTLEMENT

    Effective comminution with dry ice and liquid nitrogen

    Due to the well-conceived instrument design and the materials used, it is no problem to comminute pre-cooled materials or samples embrittled with liquid nitrogen.
    The improved breaking behaviour enables efficient comminution also of sticky, tough-elastic or temperature-sensitive materials with dry ice or after previous embrittlement of the sample with liquid nitrogen.

  • FRITSCH CYCLONES

    Optimal sample exhaustion with FRITSCH Cyclone separators

    Clean, convenient, cool: Combine your FRITSCH Universal Cutting Mill PULVERISETTE 19 with a FRITSCH Cyclone separator for sample exhaustion. Its strong airflow ensures simple feeding, increases throughput, and reduces the thermal load of the samples.
    At the same time, the powerful airflow of the FRITSCH Cyclone separators 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: especially fast and efficient comminution with minimised thermal load and significantly higher throughput – in addition to quick and easy cleaning.
    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. Especially for exhaustion of small sample quantities, we designed the compact FRITSCH small volume Cyclone separator.
    We also offer a standard Cyclone separator.

  • COMFORTABLE OPERATION

    Complete operation at the front

    The well-designed control panel keeps all functions, including the on/off switch, easily accessible on the instrument's front panel. The rotational speed is set in increments often with the plus/minus buttons and shown on the digital display. A special clean-mode button enables the manual turning of the rotor for quick and easy cleaning in between.

  • EQUIPMENT / ACCESSORIES

    Configure your Universal Cutting Mill PULVERISETTE 19 with variable rotational speed of 50– 700 rpm exactly to your specific application

    The Universal Cutting Mill PULVERISETTE 19 is delivered without funnel, cutting tool set (consisting of rotors and fixed knives), sieve cassette, collection vessel and stands. Various funnels, collection vessels, rotors with fixed knives, sieve cassettes and stand made of various materials enable you to configure the Universal-Cutting Mill exactly for your application.

  • FRITSCH AR-App

    Augmented reality (AR) is a technology that superimposes a computer-generated image on an user's view of the real world, thus providing a composite view. In soccer broadcasts, for example, you'll find augmented reality when superimposing distances of free kicks using a circle or a line. We took advantage of this effect and programmed an app for you. Simply download the free-of-charge app in the app store of your mobile device and place our instruments as the PULVERISETTE 19 live in your laboratory.
