RETSCH® Mixer Mill Grinding Balls, 7mm

The RETSCH® 7 mm Mixer Mill Grinding Balls are high-precision milling media engineered for fine grinding, blending, and homogenization of small sample volumes in RETSCH mixer mills and compatible laboratory mills. Manufactured under strict quality standards, each ball offers exceptional dimensional accuracy and a smooth, polished surface to ensure efficient energy transfer and highly reproducible grinding results.

The 7 mm size is ideal for applications requiring finer particle size reduction, gentle yet effective milling, or working with delicate, low-mass, or limited-quantity samples. These grinding balls enable high surface contact and optimized mixing action, improving milling efficiency while maintaining excellent sample integrity. Offered in a variety of materials to suit chemical compatibility needs, they help minimize contamination and meet the demands of diverse laboratory workflows.
