Mini-Mill Pulverisette 23
The ultra-compact FRITSCH Mini-Mill is ideal for fine comminution of smallest quantities of medium-hard, brittle and moist samples – wet, dry or cryogenic. Its special spherical grinding bowl ensures a much better performance in grinding, mixing and homogenizing compared with similar models. With a footprint of just 20 x 30 cm and a weight of 7 kg it easily fits anywhere; it’s smart, user-friendly, inexpensive and convinces with impressive results, small, fast, effective.
The FRITSCH Mini-Mill PULVERISETTE 23 grinds the sample through impact and friction between grinding balls and the inside wall of the grinding bowl. For this, the grinding bowl performs vertically oscillating movements with 900 – 3,000 oscillations per minute at 9 mm amplitude.
In contrast to similar mills, a clearly better degree of efficiency is achieved due to the spherical-shaped inside of the grinding bowl, which is perfectly adapted to the communition principle.

GRINDING BALLS
For achieving best grinding result grinding balls are available in ≤ 3 mm – 15 mm diameters and in 2 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion. The 5 ml PTFE bowl is especially suited for biotechnology applications. The recommended number of balls per grinding bowl can be found in the selection aid.
GRINDING BOWLS
Please select 1 grinding bowl, which is offered in the sizes 15 ml, 10 ml and 5 ml to perfectly match your sample volume. The useful capacity of the grinding bowls can be found in the selection aid. For the best grinding results all grinding bowls are available in 3 different materials thus directly preventing contamination of the samples as a result of undesired abrasion.
