Grinding balls are also available in silicon nitride, sintered corundum (99.7% Al2O3), hardened steel and tungsten carbide. Smaller grinding balls 0.5 to 4mm
dia. (to achieve a fineness down to the Nanometer-range), as well as 10mm and 20mm (have a look at grinding balls for Planetary Mono Mill Pulverisette 6

Typical fields of application:
Samples preparation, for example, for chemical analysis, chromatography, mass spectrometry or X-ray structural
analysis. Preparing samples for genetic research, for homogenising of active ingredients, preparation of extracts in the
forensic analysis, milling of pigments or other precious materials.
Method of operation:
Vertical oscillations of the grinding jar with high amplitude generate a particle-size reduction through the impact of
the grinding balls and friction between balls and the grinding jar wall.
Features of performance:
- rapid, reproducible grinding
- quick fastening of the grinding jar
- adjustable and reproducible grinding time
- regulated oscillation frequency (15 to 50 Hz)
- oscillation amplitude 9mm
- ease of maintenance and easy cleaning of the grinding parts
- safety tested (CE mark)
- 2 year warranty
Equipment:
delivered without grinding jar and ball. Please choose the grinding jar and balls from the list below, because otherwise
