Disposable Centrifuge Tubes
Product Code : EL-BLS-10971
Last updated: 6 October 2026
Quick answer: Sterile polypropylene conical centrifuge tubes with moulded raised graduations and plug-seal screw caps. The 15 mL tube is 11.8 cm long with a 1.7 cm outside diameter; the 50 mL tube is 11.5 cm long with a 2.9 cm outside diameter.
Two details in this listing matter for repeated use. The graduations are moulded and raised rather than printed, so they survive handling and do not wash off in solvent; and the caps are plug-seal screw caps, specified to prevent leakage, which is what you need in a swinging-bucket rotor where a leak contaminates the whole bucket.
The conical design is stated to promote compact, easy and complete separation, which is the point of a cone: the pellet collects in a small defined volume rather than spreading across a flat base, so the supernatant can be drawn off without disturbing it.
Both sizes are published with dimensions. The 15 mL tube is 11.8 cm long with a 1.7 cm outside diameter; the 50 mL tube is 11.5 cm long with a 2.9 cm outside diameter, so the two are nearly the same length and will sit in the same rack depth. Both are sterile polypropylene.
The maximum rated g-force is not published, and it is the figure that decides whether a tube survives the spin. Ask for it, along with the pack quantity and the sterilisation method, before ordering.
