07/11/2014: Better grinding performance

The ultra-compact Fritsch Mini-Mill Pulverisette 23 is the ideal assistant for fine comminution of smallest quantities – for wet grinding as well as for dry or cryogenic grinding. 

It's special, spherical grinding bowl ensures much better performance in grinding, mixing and homogenising compared with similar models. With a footprint of just 20 x 30cm and a weight of 7kg, it easily fits anywhere. It’s smart, is extremely user-friendly, inexpensive and convinces with impressive results: small, fast, effective.

For perfect, loss-free grinding results in shortest times! Ideal 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, pulping of seeds
  • 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
The 5ml PTFE bowl is specially suited for using the Fritsch Mini-Mill 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 this special plastic bowl and a 10 mm steel ball. It is also possible to pre-cool the entire bowl in liquid nitrogen.

Simply clever!
"In special consideration of the ball mill grinding concept, we developed for the Pulverisette 23 a grinding bowl with interior walls that are spherical instead of cylindrical. Your advantage, unmatched grinding performance with a significantly improved grinding effect, much easier recovery and simpler cleaning," say the company.

"The spherical grinding bowls of the
Pulverisette 23 are assembled simply and quickly, just twist and turn!"
