Typical fields of application
Ideal for sample preparation, for example, for chemical analysis, chromatography, mass spectrometry or X-ray structural analysis. Can be used for preparing samples for genetic research, for homogenizing of active ingredients, preparation of extracts in the forensic analysis and milling of pigments or other precious materials. The pulversiette 23 is also specially suited for the assessment of biological samples and for cryo-comminution of deep freeze of refrigerated soft samples.

Method of operation
Vertical oscillations of the grinding bowl with high amplitude generates a particle-size reduction through the impact of the grinding ball and friction between ball and grinding bowl wall.
