These conical centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. The "skirted" bottom allows the tubes to stand upright without a separate test tube rack, and the leakproof caps have a flat top surface for easy marking and labeling. The 30mL tubes may be centrifuged at up to 7,000 x g and the 50mL tubes at up to 15,000 x g.
