The Fritsch mini-mill Pulverisette 23 is designed for the fine comminution of small quantities - including wet, dry or cryogenic grinding.
According to Fritsch, its spherical grinding bowl ensures better performance in grinding, mixing and homogenising compared with similar models.
Fritsch claims it is deal for:
Chemical analysis: Comminution and homogenisation of grinding samples for creation of compacts for x-ray fluorescence and infrared spectroscopy (e.g. potassium bromide tablets).
Environmental research: Soils in contaminant analysis, humic acid determination, botanical materials in residue analysis of fertilisers and pesticides.
Pharmaceuticals and medicine: Kidney and gallstone analysis, breaking up tablets, pharmaceutical ingredients.
Forensic analysis: Hair analysis for genetic testing and drug tests, preparation of extremely small particles for chemical analysis, textile fibre and bone analysis.
Biotechnology: Comminution of deep frozen tissue samples.
Material synthesis: Creating mixtures for catalytic tests on polymers, ceramic analysis.
Its 5 ml PTFE bowl is especially suited for using the Fritsch Pulverisette 23 in biotechnology applications.
For example, it is possible to break up fungus or yeast cells, deep frozen tissue and cells in only a few minutes with a 10 mm steel ball. It is also possible to pre-cool the entire bowl in liquid nitrogen.
