Cyclone for Variable Speed Rotor Mill provides fine grinding of Difficult Samples

The Fritsch Variable Speed Rotor Mill PULVERISETTE 14 grinds rapidly and effectively soft to medium-hard, brittle as well as fibrous samples. Due to its very efficient air-cooling and the cyclone, even the comminution of difficult to grind samples such as temperature sensitive powder coatings and plastic samples or slightly moist materials such as herbs, leaves or teas are no problem.

The efficient air routing inside the PULVERISETTE 14 and the powerful air vortex within the Fritsch Cyclone cools the sample during grinding, reduces the thermal load of the sample, minimises clogging of the sieve rings while simultaneously increasing the throughput significantly. Also, the cleaning of the mill itself is reduced to a minimum. The airflow inside the Fritsch Cyclone leads the ground sample directly into the screwed-on sample glass. This type of sample discharge is the most convenient, because the ground material is drawn directly into the glass bottle where it can be transported, stored and easily removed for analysis. Thereby, the fine dust is retained in the cyclone by the HEPA dust filter resulting in increased performance for a particularly fast and effective grinding that minimises the thermal load. The PULVERISETTE 14 is the ideal solution for especially heat-sensitive materials, as well as for smooth pre-crushing and fine grinding of hard-brittle to soft, fatty or samples with residual moisture. All of this is available along with simple, contamination-free cleaning effort.

Extremely difficult to grind or acutely temperature-sensitive samples such as styrene, polyester, synthetic resins, foils, PVC, PP and PE can be embrittled by adding liquid nitrogen and afterwards ground with the PULVERISETTE 14.

An extensive range of accessories is available for the Fritsch Centrifugal Mill to help you configure your PULVERISETTE 14 for your specific application. Fritsch experts will gladly advise you.
