The FRITSCH Variable Speed Rotor Mill Pulverisette 14 is designed to effectively and rapidly grind soft to medium-hard, brittle as well as fibrous samples.
Efficient air cooling means that the Pulverisette 14 can also deal with difficult to grind or temperature-sensitive samples and plastics.
The mill also features FRITSCH-impact blades which, together with a sieve ring, enable very gentle sample grinding.
Pulverisette 14 is suitable for especially 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.
Samples that are extremely difficult to grind or temperature-sensitive such as styrene, polyester, synthetic resins, foils, PVC, PP and PE can be embrittled by adding liquid nitrogen before grinding.
Throughput varies at between 0.05 and 5 litres per hour depending on materials. Rotors, sieve rings and collecting vessels made of different materials and in different sizes enable an optimal adjustment of the instrument to the application.
Product features:
- Rapid sample throughput with high-speed grinding and simple cleaning.
- Simple change of all grinding parts without tools.
- Contamination-free cleaning and assembly of all grinding parts outside the instrument.
- Variable speed adjustment from 6,000 to 20,000 rpm.
- Automatic speed following system for constant grinding.
- Efficient air cooling of the rotor, motor components and grinding material thanks to efficient airflow routing.
- Grinding parts made of stainless steel, pure titanium, TiN-coated and WC-coated
- Rapid-action clamping lock
- With a feed particle size of < 10 mm, a final fineness of up to 40 µm can be achieved.
