The smallest instrument for smallest quantities
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.
