The mixer mill RAM255 is a compact versatile benchtop unit, which has been developed specially for dry grinding of small amounts of sample. 
It can mix and homogenize powders in only a few seconds. 
It is also perfectly suitable for the disruption of biological cells as well as for DNA/RNA extraction.

Application Examples
alloys, animal feed, bones, ceramics, cereals, chemical products, coal, coke, drugs, glass, grains, hair, minerals, oil seeds, ores, paper, plant materials, sewage sludge, soils, straw, tablets, textiles, tissue, tobacco, waste samples, wood, wool, etc...
