The Cole-Parmer SamplePrep BM-400 Mixer/Mill (SPEX #8000M), is a high-energy ball mill that grinds up to 0.2 - 10 grams of dry, brittle samples. The vial, which contains a sample and one or more balls, is shaken in a complex motion that combines back-and-forth swings with short lateral movements, each end of the vial describing a figure-8. The clamp's motion develops strong G-forces in the vial, to pulverize the toughest rocks, slags and ceramics.
