Chemglass Addition Funnel 25 ml Graduated 24/40 Joint with PTFE Stopcock

The Chemglass CG-1712-15 Addition Funnel is a 25 mL capacity, graduated glass funnel designed for controlled and precise addition of liquids to a reaction vessel in a laboratory setting. It features a 24/40 standard taper outer joint at the bottom, allowing for a secure connection to a corresponding inner joint on a reaction flask or other glassware. A key feature of this funnel is the integrated PTFE (Polytetrafluoroethylene) stopcock, which provides a greaseless and chemically resistant seal, enabling fine control over the liquid flow rate. The graduations on the funnel body allow for accurate measurement of the added liquid volume. This type of addition funnel is ideal for slow, controlled addition of reagents, especially in air-sensitive or moisture-sensitive reactions, or where precise stoichiometry is required.
