Rotor / Beater Mill

Variable Speed Rotor Mill PULVERISETTE 14 Classic Line

The ideal mill for fast comminution of soft to medium-hard materials, brittle, fibrous and temperature sensitive samples. The capability of using liquid nitrogen for embrittlement before grinding in the PULVERISETTE 14 Class Line is extremely useful for samples such as polyesters, PP, styrenes, PE, etc.
