What to consider before buying

When choosing a long stem funnel, consider the stem length and diameter relative to your flasks or containers. Borosilicate glass is heat-resistant and chemically inert, ideal for most lab work, while polypropylene is unbreakable but less heat tolerant. Check the rim finish; fire-polished rims reduce chipping and are safer. For frequent use, invest in a reinforced rim model. Ensure the stem is long enough to reach into narrow-neck vessels for splash-free transfer.
