More powerful frequency converter
With a more powerful frequency converter, the modified 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.
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.
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: 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.
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.
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.
