Zirconium Oxide Beads for cell lysis.

• Lysis of animal tissues, wood, seeds, clay, bacteria, ancient and dried samples
• Average size: 1.70–2.3 mm
• Hardness: Vickers 900–100
• Specific gravity: 5.5
• DNase- and RNase-free

Zirconium oxide has very high density and high tensile strength and hardness, and is effective at breaking very tough and hard samples, including organisms within a tough or dense exterior matrix. This is useful in applications such as isolation of intact organelles, and super-molecular structures where lysis conditions necessitate high impaction but low shearing. Effective for isolation of RNA and proteins from bacterial aggregates, biofilms, and whole insects.
