Speed rotor mill PULVERISETTE 14

Variable Speed Rotor Mill PULVERISETTE 14, for fast, effective comminution of soft to medium-hard, brittle and fibrous materials and temperature-sensitive samples.

Application area:

Soft materials such as plants, wood, roots, leaves, needles, spices, textiles, leather, chemicals, food, cereals, cellulose, fillers, chalk, kaolin, coal, soil (without stones). Medium-hard substances such as pharmaceuticals, coated tablets, tablets, fertilizers, pellets, animal feed. Temperature-sensitive samples can be comminuted because the fast, effective grinding reduces the thermal load on the material to be ground. Samples that are difficult to grind, such as styrene, polyester, synthetic resins, films, PVC, PP and PE, can be embrittled by adding liquid nitrogen, for example, and then ground to analytical fineness. In addition, the Variable Speed Rotor Mill PULVERISETTE 14 is also used for sample preparation according to RoHS.
