Use these powerful ball mills for mechanical alloying, slurry grinding, blending powders, mixing emulsions, and mechanochemistry. The sample is placed in a grinding vial with one or more balls, then shaken vigorously. The clamp swings back-and-forth 2-1/3” (5.9 cm) with a short lateral “figure-8” movement, producing strong G-forces on the vial to pulverize the toughest samples. Adjustable clamp accepts vials in various materials to effectively grind all sample types and to avoid contamination from specific elements. View time remaining on the digital display. Pause and stop buttons let you pause or stop any time during the process. Order dual-clamp model for high-throughput applications.

These rugged mixer mills come with many safety features. Vibration detection switch shuts down the mill in the event of mechanical failure. Safety interlock and lid latch ensure user safety. Forced air cooling fan prevents overheating. Shock-mounted electric motor cuts back vibration and prolongs motor life. Steel housing and rugged construction ensure a long life of heavy work.

The BM-400 Mixer/Mill® is a high-energy ball mill designed to quickly and efficiently pulverize tough, brittle materials into fine powders. Grinds dry, brittle samples ranging from 0.2 to 10 grams. Whether you're working with rocks, slag, ceramics, or minerals, this mill delivers consistent, high-quality results with minimal effort.

Typical applications include: mechanical alloying, slurry grinding, blending powders and mixing emulsions.

Typical samples include: rocks, minerals, sand, cement, slag, ceramics, catalyst supports, glass, pharmaceuticals, plant and animal tissue, cannabis, seeds, paints, and ink.

The Cole-Parmer SamplePrep BM-400 Mixer/Mill is ideal for rock, mineral, sand, cement, ceramics, catalyst supports, and more. 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.

The versatile and multi-purpose Mixer/Mill is not just for grinding, it also blends powders, make emulsions, and aids in mechanical alloying. It works with a variety of vial materials including hardened steel, stainless steel, tungsten carbide, alumina ceramic, zirconia ceramic, silicon nitride, agate, polystyrene, methacrylate, and polycarbonate.

Setup is simple, just load your sample and grinding media, secure the vial, and start the mill. The unique figure-8 motion ensures thorough mixing and even particle size reduction, and its compact design makes it easy to integrate into any lab setting.

The Cole-Parmer SamplePrep BM-400 Mixer/Mill is designed for safe operation with a safety interlock system that stops the motor if the lid is opened during operation, ensuring safe operation during use. The vibration detection switch shuts down the mill in the event of a mechanical failure, and the forced air cooling fan prevents overheating. The shock-mounted electric motor cuts back vibration and prolongs motor life, and the steel housing and rugged construction ensure a long life of heavy work.

Effective September 2023, the Spex SamplePrep 8000M Mixer/Mill® has now been rebranded Cole-Parmer® SamplePrep under model number BM-450 Mixer/Mill®. All the same great features and specifications, just with a new and improved look.
