The Cole-Parmer SamplePrep BM-450 Mixer/Mill reduces hard, brittle samples from 0.2 to 10 grams to analytical fineness. The Mixer/Mill handles rocks minerals, ceramics, slags, catalyst supports, cements, and more. It is ideal for high-energy applications like mechanical alloying and mechanochemistry.

The dual clamp design of the BM-450 Mixer/Mill ensures maximum efficiency. The ability to process two samples simultaneously doubles your throughput. The dual clamps of the BM-450 Mixer/Mill not only allow twice as many samples to be ground in a given time, but they also move in symmetry, reducing vibration and extending the life of the mill’s components.

The Mixer/Mill is version and multi-purpose blending powders, creating emulsions, and homogenizing samples with ease. Various grinding vial materials are available including hardened steel, stainless steel, zirconia ceramic, silicon nitride, agate, polystyrene, methacrylate, and polycarbonate.

Each grinding vial contains a sample and one or more balls. It is then shaken in a complex motion that combines back-and-forth swings with short lateral movements in the shape of a figure-8. The clamp's motion develops strong G-forces in the vial, to pulverize the toughest rocks, slags and ceramics.

Smart, user-friendly features include a digital timer for precise control over grinding time, and the forced air cooling system keeps the motor and clamp running smoothly.

The Cole-Parmer SamplePrep BM-450 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.

Powerful and efficient, the Cole-Parmer SamplePrep BM-450 -Mixer/Mill reduces processing time for high-throughput labs, minimized sample contamination with a variety of vial materials to choose from, and with its durable construction, ensures long-term reliable performance.

Operation is simple: load the sample and grinding media into the vial, secure the vial in the dual-clamp system, set the desired run time and speed on the digital interface, press start, and let the Mixer/Mill do the work.
