Pear Shape vs. Cylindrical for Dropwise Addition
A pear-shaped dropping funnel holds most of its liquid lower in a wider body that tapers toward the stopcock, which keeps the remaining liquid level more visible as the addition proceeds compared with a straight-sided cylindrical funnel. The drip stem is shaped to deliver the reagent as a controlled stream of drops rather than a dribble down the flask wall, and having the stem seated inside the ground cone keeps the assembly compact where bench or fume-hood clearance above the reaction flask is limited.
