PULVERISETTE 7 Planetary Mill
The premium-class PULVERISETTE 7 planetary micro mill, featuring two grinding stations, is designed for a wide range of applications. It is ideally suited for the loss-free grinding of hard, medium-hard, and brittle materials down to a final fineness of 50 nm. Depending on the desired final particle size, grinding can be performed dry, in a suspension, or under an inert gas atmosphere.
In addition to grinding, these planetary mills can also be used for mixing and homogenizing emulsions and pastes, as well as for mechanical activation and alloying in materials science research. Technical Data
