Dual Mixer/Mill® 8000D – High Energy Ball Mill

The newly redesigned SPEX Dual Mixer/Mill 8000D is a high energy ball mill with dual clamps 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 new design provides a more robust housing that ensured longevity and reliability. The new control panel also facilitates simple operation.

Other features that make it suitable for use in your lab include, increased sound-proofing for reduces noise and while vibration damping makes the Mixer Mill suitable for benchtop operation.

  • Accepts all SPEX SamplePrep Mixer Mill(R) Grinding and Mixing Vial Sets.
  • Also called a shaker mill or high-energy ball mill.
  • Dual clamps enable multiple sample processing for high-throughput applications.
  • Efficient two-clamp laboratory mill commonly referred to as the “SPEX Mill”.
  • Equipped with forced-air cooling and safety interlock system for operator protection.
  • Standard running times up to 100 minutes. Optional run time chip for cycles up to 175 hours
  • For efficiency, clamps are run in balance with the same vial and load in each clamp
  • For grinding multiple samples in the 0.2 – 10 gram range or mixing up to 60 mL of multiple sample per clamp.
  • Reduces samples to analytical fineness and can be utilised for mechanical alloying and nanomilling.
  • Shock mounted motor enables bench top operation.
  • Steel housing protects the clamp mechanism and rugged construction ensures a long life of heavy work
  • The 8010 and 8011 Multiple-Sample Adapters permit processing of multiple smaller samples.
  • Wide selection of grinding and mixing vials available including hardened steel, stainless steel, tungsten carbide, alumina ceramic, zirconia ceramic, silicon nitride, agate, polystyrene, methacrylate, polystyrene, and polycarbonate.
