In many laboratories, samples are still ground using a hand held pestle and mortar. Despite the fact that a better method has been available for many years: namely the mortar grinder Pulverisette 2. With this mill, the pestle is held against the wall of a rotating mortar bowl with adjustable, reproducible spring pressure. The grinding time is set with a digital timer. A scraper on the inside wall of the mortar bowl ensures that the sample is always re-directed towards the fixed pestle. The Pulverisette 2 grinds the sample through friction, which means that there is no thermal load on the material unlike a ball mill. The result is considerably more homogeneous and reproducible than grinding with a hand mortar also the mill is very easy to clean. The mortar bowl and pestle can be removed without tools in just two easy motions for quick cleaning.
