PPCO high-speed round-bottom centrifuge tubes range from 4ml to 120ml, covering small samples through larger laboratory separations. Every listed size uses a clear screw cap, while tube diameter and height change with capacity to suit different adapters and equipment. The rounded base supports clarification, concentration and sample recovery without corners at the tube tip. Confirm the selected tube, cap, fill level, adapter and rotor combination before use.
