200 µm Acid Washed Zirconium Beads, 250 gm 

Tougher than silica, less expensive than stainless steel, and inert in most solutions, 200 µm Zirconium Beads (Zirconium Silicate) are suitable for disrupting bacteria and small yeasts (e.g. Pichia).

Acid Washed Zirconium Beads are ready-to-use, having been treated with acidified water to remove fine particles, dust, and other impurities typically found in untreated beads, then further baked to drive off organic impurities.
