Reinforced Tubes with Screw Caps & EPDM O-Rings, 2 mL (500/pk)

These 2.0 mL reinforced polypropylene tubes withstand the impact of bead beating during bead milling and homogenization, providing durability and secure sample containment. Each tube includes a screw cap with an O-ring for airtight sealing, that helps maintain sample integrity under high-speed conditions and prevents leaks during processing. Recommended for use with Omni Bead Ruptor bead mill homogenizer systems, they support a working range of 200 µL to 1.5 mL and can endure temperatures from –80 °C to 121 °C, offering versatility of use within the laboratory. Tubes are certified RNase/DNase-free, making them suitable for most molecular biology applications, including DNA and RNA extraction after tissue disruption. Other popular workflows include protein or lipid isolation, along with downstream metabolite or elemental analysis.
