Grinding Jars and Balls

Different materials have different grinding requirements. Very hard samples require a jar and grinding balls that are just as hard or harder for effective sample preparation. Some samples are easily contaminated and require metal-free or inert grinding materials. Benchmark offers a variety of jars and balls to meet these differing needs. All of the jars feature threaded closures for leakproof performance with both solids and liquids.

Tungsten Carbide Jars

Tungsten carbide is an exceptionally hard ceramic material. It is useful for grinding materials where the presence of trace metals may be a concern. Applications include preparation of samples for XRF and particle reduction of ores, minerals, metal oxides and cement clinkers. These jars are extremely durable and offer a long service life. 10mm tungsten carbide grinding balls and 25ml jars are available.
