The TE250 Laboratory Ring Pulverizer can be used to pulverize a variety of materials to analytical fineness. Also known as a "ring and puck mill" or "shatterbox", the TE250 can pulverize as little as 10cc or as much as 250cc at a time. Grinding containers are typically constructed of chromesteel or tungstencarbide, but nonmetallics like ceramic and agate containers are also available.
