For a grinding of organic materials, we recommend using bowls and balls made of sintered corundum (Al2O3). Fibrous materials will be comminuted much more efficient, compared to smooth surfaced grinding materials.

With its rough surface, Al2O3 uses to produce also higher abrasion (compared to smooth surfaced grinding materials).

For a grinding of temperature sensitive samples, it is possible programming a stepwise grinding with e.g. 1 minute of grinding time and 3 minutes of pausing times for chilling.

For a better fineness, also a grinding in suspension is possible (see result 2).

Second sample has been ground together with 50 ml of water. After 5 minutes of grinding in suspension, a pasty sample was achieved with no particles > 500 µm. Even longer grinding times are plausible for a further size reduction.

By longer grinding times in suspension, over pressure should be avoided. For this, we recommend programming a stepwise grinding with double pausing times (e.g. 3 minutes of grinding + 6 minutes of programmed pausing times).
