When a Solid Glass Stopcock Is the Right Choice
A solid glass stopcock key is a lower-cost option than PTFE or needle-valve alternatives, and remains a reasonable choice for light, routine use where the funnel is not in constant daily rotation across different reagents. Glass-on-glass contact means the key benefits from occasional greasing to keep it turning smoothly and sealing well, and it can be more reagent-sensitive than PTFE with certain aggressive chemicals, so buyers working with a wide range of solvents may prefer the PTFE stopcock version instead. The bore size selection works the same way as on the other stopcock variants in this range.
