Laboratory disc mills by SIEBTECHNIK TEMA
The laboratory disc mill enables fast, loss-free and reproducible fine comminution and homogenization of the samples. The grinding barrels can hold sample batches of 10 – 1000 cm³ and grind and homogenize the sample material to final finenesses of up to < 40 μm *1) in a single step. Sample preparation with a laboratory disc mill is thus the ...
