  • OVERVIEW

    Effective comminution due to highest rotor speed

    The FRITSCH Variable Speed Rotor Mill PULVERISETTE 14 classic line is the ideal mill for fast, effective comminution of soft to medium-hard, brittle and fibrous materials as well as temperature-sensitive samples – proven worldwide for the use in trace analysis.

    Difficult-to-mill samples, or extremely temperature-sensitive samples such as styrenes, polyester, synthetic resins, films, PVC, PP and PE can be embrittled with the addition of liquid nitrogen and afterwards ground in the PULVERISETTE 14 classic line. The motor speed can be varied between 6,000 and 20,000 rpm in increments of one-thousand - making it possible to adapt the mill to each specific application. An automatic speed compensation feature ensures an ideal adaptation of the grinding to the specific comminution behaviour of the sample. At the same time reduces the fast, effective grinding significantly the thermal strain on the sample.

  • WORKING PRINCIPLE

    Impact and shearing

    Inside the Variable Speed Rotor Mill PULVERISETTE 14 classic line, the sample is comminuted by impact on the ribs of the rotor rotating at a high speed and additionally sheared between the rotor-teeth and between the utilized sieve ring.

  • FEATURES
    • Rapid sample throughput due to high-speed grinding
    • Max. feed size 10 mm, max. throughput 5 l/h
    • Final fineness d50 < 40 μm, sieve rings 0.08 – 6 mm
    • Ideal for minimal sample quantities < 10 ml
    • Simple, tool-free changing of rotor, collecting vessel, sieve ring and labyrinth seal
    • Simple, contamination-free cleaning and assembly of all grinding parts outside the instrument
    • Heavy-metal and iron-free grinding and sample preparation according to RoHS
    • Comminution of difficult-to-mill and temperature-sensitive samples – also cryogenic
    • Variable speed settings between 6,000 and 20,000 rpm
    • Automatic speed regulation for constant milling
    • Efficient cooling of the grinding chamber due to extremely high airflow
    • Highly durable low-wear rotor made of stainless steel
    • Grinding chamber made of stainless steel or PTFE-coated with practical quick-clamping lock
    • Grinding parts made of stainless steel, pure titanium and TiN-coated
    • Maintenance-free three-phase motor with regulated rotor speed 6,000 - 20,000 rpm
    • High speed stability even under full load
    • Wear-free labyrinth seal between the grinding chamber and drive motor
    • Removable dust filter for convenient cleaning
    • Ergonomic operating panel with membrane keyboard and timer
    • Microcontroller with integrated regulation function for Vibratory Feeder
    • Optimal for fine comminution after pre-crushing with the FRITSCH Cutting Mills
    • Temperature gentle fine grinding with the FRITSCH Cyclone separators
    • Extensive accessories available – easing your laboratory tasks

  • WORKING FASTER

    More powerful frequency converter

    With a more powerful frequency converter, the Speed Rotor Mill PULVERISETTE 14 classic line ensures that the motor output is precisely matched to the grinding material.
    Your advantage: faster sample feeding, a constant rotational speed and a higher throughput. The well-designed LED display in the ergonomic operating panel with membrane keyboard, displays the speed and motor load and alerts in the event of reaching the temperature limit and overload.

  • EFFICIENT COOLING

    Ingenious air routing

    Available only from FRITSCH: The ingenious air routing of the PULVERISETTE 14 classic line ensures a constant airflow to cool the rotor, all motor components and the grinding material in the collecting vessel. At the same time, a large fan blows the cooling air into the instrument through a foam particle filter to create positive pressure that prevents the penetration of dirt particles from the ambient air.

  • EXCHANGE OF GRINDING TOOLS WITHOUT TOOLS

    Fast exchange of all grinding tools - easy cleaning

    All grinding parts can be removed without tools with just a few motions – for quickly exchanging all grinding parts and for cleaning them outside of the instrument. The especially smooth surface of the stainless steel impact rotors simplifies a thorough cleaning – fast and easy! The wear-free labyrinth seal between the grinding chamber and the motor offers secure protection against contamination of the instrument.

  • NEW: FRITSCH CYCLONES

    NEW: temperature gentle fine grinding with the FRITSCH Cyclone separators

    In combination with the FRITSCH Cyclones the Variable Speed Rotor Mill PULVERISETTE 14 classic line is ideal for ultra-fine grinding of temperature-sensitive samples like powder coatings and plastic samples or for smooth pre-crushing and fine grinding of hard-brittle to soft, fatty or samples with residual moisture.
    Small volume Cyclone separator: The compact FRITSCH small volume separator completely made of plastic can be dismantled completely and cleaned in the dishwasher thus reliably preventing contaminations. The comminuted sample is collected in a screwed-on sample glass of 250 or 500 ml volume. The small volume Cyclone separator can be combined with the exhaust system, which can be ordered along, or can also be used with the supplied fine-dust filter 80-100 µm for passive utilization.
    High-performance Cyclone separator: Especially for the analytical sector and for the food and pharmaceutical industries is the high-performance separator completely made of stainless steel 304 in combination with the exhaust system indispensable. The exhaust system for the operation of the FRITSCH Cyclones may be ordered along.
    The result: an especially fast and effective comminution with minimized thermal load with significantly higher throughput and especially fast and easy cleaning.

  • EQUIPMENT / ACCESSORIES

    Configure your Variable Speed Rotor Mill PULVERISETTE 14 classic line exactly to your specific application

    The Centrifugal Mill PULVERISETTE 14 classic line includes a collecting vessel and lid. In order to operate the mill, you must also order a rotor, a sieve ring, an impact bar or a pin insert - allowing you to select your grinding tools according to your specific application! To ensure this, an extensive accessory programme for the PULVERISETTE 14 classic line is available with rotors and sieve rings in various designs and materials, as well as additional accessories. Choose exactly what you need!

    For grinding large quantities we recommend the special conversion kit. This allows the comminution of sample quantities of up to 1 litre in a single step without the need to open the grinding chamber and empty the collecting pan during the process.

    View extensive accessories

    Combine your PULVERISETTE 14 classic line with the FRITSCH Vibratory Feeder LABORETTE 24 to ensure continuous feeding of the sample during the entire grinding process, even of smallest quantities. Due to a direct connection, the mill automatically matches the sample feeding to its load state at any given moment.
