Centrifuging

Part of speech: verb

Definitions

1. The technique involves rotating a sample at high speed to differentiate its components based on their density values
2. This method utilizes centrifugal force through fast spinning to segregate varying mass elements within a mixture
3. This process employs rapid rotation to separate materials based on density differences found in a heterogeneous mixture

Etymology: This is the present participle or gerund of "centrifuge," so the story belongs to that base verb and the "-ing" ending is simply the ordinary English marker for an ongoing action. "Centrifuge" was formed in the 19th century from the Latin "centrum" (centre) and "fugere" (to flee), following the pattern of "centrifugal," the term for a force pushing outward from a rotation's centre. The Latin "fugere" also gives English "fugitive" and "refuge," so the same root is at work in both. The machine was named after the principle it uses. Spinning a mixture pushes its heavier particles toward the outer edge while lighter material stays nearer the middle, so the separation literally flees the centre. Scientists used the word for the apparatus first, and the verb followed from it.

Synonyms: spinning, whirling, rotating
