> Grinding Balls

Larger and more resilient samples can be homogenized through the use of grinding balls. In contrast to grinding beads, which are a pool of beads within a given size range, grinding balls are spherical and precision ground to a specific diameter.

Grinding balls are made of stainless steel, tungsten carbide, or zirconium oxide, their larger size makes them more suitable for grinding, whereas beads have insufficient mass to accomplish this.

Prior to packaging, grinding balls are treated to remove residual oils and other contaminants.
