Variable-speed rotor mill PULVERISETTE 14
The FRITSCH PULVERISETTE 14 classic line variable-speed rotor mill is ideally suited for the rapid and efficient comminution of soft to medium-hard, brittle, and fibrous materials, as well as temperature-sensitive samples; it has proven its reliability worldwide in the field of trace element analysis.
Samples that are difficult to grind or are highly temperature-sensitive—such as styrene, polyester, synthetic resins, films, PVC, PP, and PE—can be embrittled using liquid nitrogen and subsequently processed in the PULVERISETTE 14 classic line. The motor speed can be adjusted from 6,000 to 20,000 rpm in increments of 1,000 rpm, allowing the mill to be tailored to each specific application. An automatic speed compensation feature ensures that the grinding process is optimally adapted to the specific grinding characteristics of the sample. At the same time, the rapid and efficient grinding process significantly reduces thermal stress on the sample. Technical Data
