Microcentrifuge tubes filled with grinding media (e.g., beads or balls), are widely used to homogenize samples, such as microorganisms and tissue. OPS Diagnostics offers convenient, ready-to-use pre-filled disruption tubes in multiple configurations, minimizing preparation time by researchers. All OPS Diagnostics’ grinding media is cleaned to remove impurities and available in a variety of materials, sizes and treatment types. Bead sizes range from 100 µm - 6 mm, and tubes are available in skirted (i.e., self-standing) or unskirted (i.e., conical) tubes.
Pre-filled tubes are offered with Zirconium Silicate (“Zirconium”), Silica, Mixed Media and Stainless Steel grinding media. All grinding media will generate heat during sample processing.
Acid Washed Pre-Filled Tubes
Acid Washed Beads are washed in an acidic solution and oven baked to remove detrimental contaminants found in raw beads.
Molecular Biology Grade Pre-Filled Tubes
Molecular Biology Grade Beads undergo the same process as acid washed and then are further processed and aseptically packaged. They are certified free of nucleic acids.
