Thistle Funnel Diagram - Lab Equipment Illustration #1398562 (License: Personal Use)

This black-and-white line drawing depicts a classic thistle funnel, characterized by its wide octagonal upper chamber that tapers into a narrow stem with a horizontal bar near the base-used to rest on the rim of a container or support a filter paper. The design allows for slow, controlled addition of liquids while minimizing splashing or spillage. It’s frequently employed in titrations, filtration, and gas-washing setups in academic and industrial labs.

Used in chemistry education materials, lab manuals, safety guides, and equipment catalogs; targets students, educators, and lab technicians seeking clear visual references for glassware identification and usage.
