® 8530 Now CE Approved! Since its introduction three decades ago, the SPEX SamplePrep Shatterbox® has become the most popular “swing mill” in America. It remains the most efficient way to pulverize up to 100 grams of brittle material to analytical fineness. Shatterboxes typically grind cement, rocks, slags, soils, ceramics, and ores, but have been used for hundreds of other materials including sulfur pellets, dried marsh-grass, and pharmaceuticals. Programmable, Portable, and Safe This enclosed, advanced design features the ease of use of a cam-action clamp. The clamp bar is held down securely by a cam-activated lever. The electronic controls allow programmed running times up to 10 minutes. As the Shatterbox runs, the timer display counts down the minutes and seconds remaining. A “pause” function allows interruption of a grinding cycle. Safety features include a safety interlock and gas cylinders for the lid. The interlock holds the lid closed whenever the mill is running, and the cylinders control movement of the lid when it is opened or closed. The sound-insulated steel cabinet has a cooling fan to prevent the motor from overheating and lockable casters with which the mill can be moved about the lab and then fixed in place.

The motor is protected by a perforated shield to allow ample air-cooling for continuous running and a rubber “skirt” shields the drive mechanism but is easy to move aside when the drive belts need replacement.

Grinding Containers and Accessories The SPEX SamplePrep Shatterbox® swings a dish-shaped grinding container in a tight, high-speed horizontal circle. Inside the container are the sample, a puck, and (in larger containers) a ring. As these grinding elements swing free inside the container, the sample is rapidly crushed between the walls of the container, puck, and rings, and further reduced by the millstone-like action of the puck and ring against the container floor. Grinding times are usually between two and five minutes, with resultant particle size well below 200 mesh. With grinding...
