The All-Purpose Mill for Rapid Comminution

The Fritsch Variable Speed Rotor Mill PULVERISETTE 14 grinds rapid and effectively soft to medium-hard, brittle as well as fibrous samples like for example in foodstuffs: rice, spices, foodstuffs for protein and nitrogen analysis, dried fruits or in biology: plants, roots, leaves, needles, grains, drugs, peat, seeds, ash.

Even the comminution of samples, which are difficult to grind or temperature-sensitive samples and plastics are no problem for the PULVERISETTE 14 due to its very efficient air cooling.

In addition to the special air cooling of the PULVERISETTE 14, Fritsch have developed the Fritsch-impact blades: due to the clever design it allows, together with a sieve ring, very gentle grinding of samples. This results in increased grinding action for a particularly fast and effective grinding, minimised heat load and provides the ideal solution for temperature-sensitive materials such as powder coatings or plastics, as well as for smoothly pre- and fine grinding of hard-brittle to soft, fatty sample or samples with a residual moisture.

For samples that are extremely difficult to grind or which are extremely temperature-sensitive like styrene, polyester, synthetic resins, foils, PVC, PP and PE can be embrittled by adding liquid nitrogen and afterwards ground with the PULVERISETTE 14.

Even when heavy-metal-(iron-)free grinding or sample preparation according to standard for RoHS-analysis is necessary, the perfect accessories are available.

The Variable Speed Rotor Mill PULVERISETTE 14 with a real top speed of 20.000 rpm is the Turbo Mill for sample preparation. With a feed particle size of < 10 mm, a final fineness of up to 40 µm can be achieved. The throughput depends on the material and lies between 0.05 and 5 litres per hour. Rotors, sieve rings and collecting vessels made of different materials and in different sizes enable an optimal adjustment of the instrument to the application.

Further advantages include: rapid sample throughput as a result of high-speed grinding and simple cleaning; simple and easy change of all grinding parts without tools; simple, contamination-free cleaning and assembly of all grinding parts outside the instrument; automatic speed following system for constant grinding; grinding parts made of stainless steel, pure titanium, TiN-coated and WC-coated; rapid-action clamping lock.
