RS 200: Vibratory Disc Mill
Brand: Retsch | Category: Scientific & Laboratory Equipment
Vibratory disc mill that homogenises medium hard, hard, brittle and fibrous samples to below 20 µm in seconds, which is the fineness spectral analysis needs. A grinding set of rings and a puck oscillates horizontally inside a sealed jar, so the sample is not exposed and loss of fines is limited.

More from Materials Testing Lab
- RS 300 XL: Vibratory Disc Mill
Large capacity vibratory disc mill taking batches from 35 ml up to 2,000 ml, for laboratories preparing large samples for spectral analysis. It reaches the same sub 20 µm fineness as the RS 200 but with grinding sets up to 2 litres, so a bulk sample does not have to be split before grinding.
- DM 200: Disc Mill
Disc mill that reduces medium hard, hard and brittle material between a fixed and a rotating grinding disc, with the gap set continuously from 0.05 mm to 5 mm. It covers both preliminary and fine grinding, and the choice of disc material governs how fine it will go and how much contamination is introduced.
- Emax: High Energy Ball Mill
High energy ball mill that combines high frequency impact with intensive friction, reaching a final fineness below 80 nm. Integrated water cooling and temperature control allow long grinding runs without the sample overheating, which is what normally limits nanoscale grinding. It is used for nano grinding, mechanical alloying and colloidal milling.
