400 µm Acid Washed Zirconium Beads, Pre-Filled Tubes (100 count) 

Tougher than silica, less expensive than stainless steel, and inert in most solutions, 400 µm Zirconium Beads (Zirconium Silicate) are suitable for disrupting bacteria and yeast.  

Zirconium beads are available in Acid Washed, Low Binding, and Molecular Biology Grade format.  Since untreated beads are notorious for containing large amounts of debris and dust, all beads are acid washed and further baked to remove organize impurities. 

Molecular Biology Grade Beads are certified nucleic acid, DNase, RNase, and protease-free.  They are most appropriate for molecular biology applications, including PCR, which may be hindered by the presence of nucleases and/ or proteases.

Pre-Filled Tubes are a convenient solution for labs seeking time savings by no longer requiring researchers to weigh, fill and QC individual tubes.   They are available in 2 ml skirted (i.e., self-standing) or unskirted (i.e., conical bottom) polypropylene tubes to ensure compatibility with most tube homogenizers. Clear screw caps with O-rings included.
