Each impact-resistant 2 ml tube contains one 6,35 mm diameter zirconium oxide coated ceramic grinding sphere.

• Use to break hard/brittle samples
• Stored at room temperatue (15 to 30 °C)
• DNase and RNase free

Specialty applications include RNA extraction from difficult samples where lysis by impaction only is preferable with minimal amounts of mechanical shearing. This grinding matrix is chemically inert and will not bind nucleic acids.
