Polypropylene round-bottom centrifuge tubes with removable caps range from 5ml to 60ml. Most sizes use separate caps across different body lengths and mouth sizes, while selected variants use leakproof-style closures. That closure designation applies only to the listed variants rather than the full range. The rounded base supports sample recovery. Choose by tube dimensions and cap style, then confirm closure performance, fill level, adapter, rotor and RCF requirements for the application.
