A device or substance that causes something to become saturated, meaning it is filled to capacity or completely soaked.
The saturator was used to ensure the fabric absorbed all the dye evenly.
Saturator → It is formed from "saturare" (meaning to fill or soak) and "-or" (meaning one who). The word "saturator" refers to one who fills or soaks something.
Think of someone who 'fills' ('saturare') something up — that's why a saturator is someone or something that fills or soaks.
