400 micron Zirconium Beads, Pre-Filled Tubes (200 count)-blue

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

Beads are available in Acid Washed, Low Binding, and and Molecular Biology Grade format.  Since untreated beads are notorious for containing large amounts of debris and dust, all beads are acid washed, at a minimum, prior to packaging. 

Low Binding Beads are chemically altered using a proprietary process to bind less biomolecules liberated from homogenized samples.  

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 polypropylene tubes to ensure compatibility with most tube homogenizers. Clear screw caps with O-rings included.
