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 like temperature-sensitive powder coatings and plastic samples or slightly moist materials such as herbs, leaves or teas are no problem for the PULVERISETTE 14.
Variable. Fast. Ideal.
The increased grinding performance of the Centrifugal Mill for a particularly fast and effective grinding minimizing the thermal load. And 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! And all this with a simple, contamination-free cleaning effort.
Our suggestion: extremely difficult to grind or acutely temperature-sensitive samples like styrene, polyester, synthetic resins, foils, PVC, PP and PE can be embrittled by adding liquid nitrogen and afterwards ground with the PULVERISETTE 14.
Cool. Clean. Convenient.
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 air flow 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.
By the way
An extensive range of accessories is available for the FRITSCH Centrifugal Mill, - configure your PULVERISETTE 14 for your specific application - our experts will gladly to advise you!
Combine your PULVERISETTE 14 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.
