30mL Oak Ridge Round Bottom Centrifuge Tube Overview
The Globe Scientific 30mL Oak Ridge Round Bottom Centrifuge Tube (SKU 6321) is a polypropylene tube built for repeated high-speed spins and reliable sealing. Its attached screw cap stays with the tube, reducing the risk of lost closures during busy workflows. Round bottom geometry distributes force across the base, supporting demanding separation protocols.
Polypropylene construction gives the tube broad chemical resistance and durability across a range of laboratory temperatures. Each tube holds a 30mL working volume in the classic Oak Ridge format trusted by molecular biology, microbiology, and biochemistry teams. Technicians benefit from a leak-resistant closure that integrates with the vessel rather than relying on separate caps.
Packaged 12 tubes per bag, this configuration suits both small benches and high-throughput facilities. LabSupplies.com supplies SKU 6321 with case quantities that simplify standing orders for institutional buyers.

Laboratory Applications
Oak Ridge tubes serve protocols that demand sturdy vessels for centrifugation, including cell harvesting, protein precipitation, nucleic acid recovery, and density gradient work. Researchers rely on the attached screw cap to maintain a closed system while handling biological samples and reagents.
Polypropylene compatibility makes these tubes suitable for many organic and aqueous solutions used in sample preparation. Microbiology labs, biochemistry groups, and industrial QC teams use the 30mL format for mid-volume separations where a round bottom helps consolidate pellets.
