The Mortar Grinder PULVERISETTE 2 is the essential instrument in the processing laboratory. It is equally suitable for universal fine grinding of inorganic and organic samples, dry or in suspension for analysis, quality control and material testing, as well as for the production and homogenizing of pastes and crèmes in a laboratory standard. Furthermore the Mortar Grinder PULVERISETTE 2 it is very well suited for cryogenic grinding - cold grinding of samples with liquid nitrogen.
Here an example: preparation of tomatoes
As a first step the tomato chunks are embrittled with liquid nitrogen. Next, they can be gently ground with the PULVERISETTE 2. As a mortar, a stainless steel grinding set is used. It has the advantage that even during the grinding process the liquid nitrogen can be added. The result: a fine, homogenous powder.
This is just one example. The full range of applications is much more comprehensive and makes it an essential tool for sample preparation. No laboratory can afford to be without!
That means: Whenever reproducible grinding conditions, short grinding times, precise results, loss-free milling and dust-free operation are required, the PULVERISETTE 2 is the perfect mill. With a material feed size of 6 - 8 mm and a feed quantity of 30 - 150 ml, a final fineness (depending on the material) of 10 -20 µm can be achieved.
Summary: We modernized the proven Mortar Grinder PULVERISETTE 2. Here the focus was set on the handling and the reproducibility of grinding tests and the possibility to observe the grinding progress due to an illuminated grinding chamber. The mortar bowl and pestle can be easily removed without tools: Ideal for the quick sampling and easy to clean!
The contact pressure of the pestle onto the mortar bowl wall is achieved via springs, in the horizontal as well as vertical direction. The contact pressure is adjustable without tools, exactly readable and therefore absolutely reproducible.
