A cone above a narrow stem.
Also known as: Conical funnel, Laboratory funnel
A filter funnel is drawn as an inverted cone above a narrow stem, directing liquid into a narrow-necked vessel and holding filter paper when filtration is intended.
Directs liquid into a narrow opening and supports filter paper for filtration.
Contexts: Laboratory
Does both jobs with the same shape, so a diagram shows filtration by the presence of the paper rather than by a different funnel.
Contexts: Laboratory
An inverted triangle above a narrow vertical tube, the wide opening uppermost.
