Round Bottom vs Conical Bottom for Centrifugation
A round-bottom tube distributes the sample more evenly around a curved base rather than concentrating it at a single tip, which suits general-purpose spinning, mixing and heating steps where a defined pellet point is not the priority. This shape is common across a wide capacity range precisely because it adapts well to different rotor and holder geometries, from small 12 ml analytical volumes up to 200 ml bulk sample prep. The graduated markings let a user read approximate volume directly from the tube during a protocol without transferring liquid to a separate measuring vessel first.
Frequently Asked Questions
What capacities are available for this centrifuge tube?
It is available in six capacities: 12 ml, 30 ml, 40 ml, 50 ml, 100 ml and 200 ml, covering small analytical volumes through to larger bulk sample preparation.
Why choose a round bottom instead of a conical bottom?
A round bottom suits general-purpose spinning, mixing and heating where a tightly concentrated pellet is not the priority, and its shape adapts well across a wide range of rotor and holder geometries and capacities.
Is this tube supplied in glass or plastic?
Material varies by capacity and application.
