Mixer/Mill® 8000M – High Energy Ball Mill

The SPEX 8000M is a high energy ball mill that accommodates sample sizes ranging from 0.2 – 10 grams. Ideal for grinding dry, brittle samples, mechanical alloying, slurry grinding, blending powders, and mixing emulsions.

The newly redesigned Mixer Mill features a more sturdy design for extended life and simplified operation through the new display. The 8000M will fit right into your lab with quieter operation thanks to more sound insulation and compact size and vibration damping that make it suitable for benchtop operation.
