Solid Glass vs. PTFE Stopcock for Extraction Work
A solid glass key stopcock is a cost-effective, chemically inert choice for routine extraction work with most common solvents, and is the traditional stopcock type still specified by many teaching labs. It does need a thin film of stopcock grease to seat and turn smoothly, and periodic re-greasing where it sees frequent use, unlike a PTFE stopcock which runs dry. Separating and dropping funnels of this kind are covered by the specifications set out in ISO 4800 (Laboratory glassware – Separating funnels and dropping funnels). This is manufacturer-stated conformance, not a claim of third-party certification — buyers with a specific tender or accreditation requirement should confirm the exact specification at enquiry stage before quotation. For a grease-free alternative, see the Separating Funnel Gilson PTFE Stopcock in the same body pattern.
