1.0 mm Zirconium Beads are suitable for homogenizing fine soil samples and softer tissues and leaves. Zirconium Beads are denser than silica beads, less expensive than stainless steel grinding balls and inert in most solutions.
Beads are available in Acid Washed 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.
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.
