Despite the fact that a better method has been available for many years: namely the Mortar Grinder PULVERISETTE 2. Thanks to the gentle grinding, one of the main applications for this mill is in the pharmaceutical industry for galenics to confirm the quantity of active ingredients in drugs (tablets and drages). The PULVERISETTE 2 is very well suited for grinding at low temperature in liquid nitrogen. First, for example tomato pieces are frozen in liquid nitrogen to make them brittle. Then they are placed in the mortar bowl and liquid nitrogen added. After a few minutes, the result is a fine, homogeneous powder. In addition to comminution, other applications for the PULVERISETTE 2 include the mixing of solids or the mixing of solids with liquids. For instance, the Mortar Grinder is used for mixing pure liquid mercury with a fine metal powder. Another application is the mixing of a metallic powder with a high viscosity synthetic resin. Using a grinding set of hardened steel and a grinding time of 30 minutes, it is possible to homogeneously mix solids to over 80 percent by weight through gradual addition of the powder. The examples described above demonstrate just some of the diverse uses for the Mortar Grinder PULVERISETTE 2. Of course, the full range of applications is more comprehensive. This capability makes it an essential tool for sample preparation which no laboratory can afford to be without.
