Fritsch Variable Speed Rotor Mill Pulverisette 14
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 this mill.
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, minimizes 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 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.
The result: increased grinding performance for a particularly fast and effective grinding that minimizes the thermal load. And the 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.
Fritsch suggests that 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.
