Lab Glassware Manufacturer manufactures, supplies and exports the Separating Funnel Gilson Solid Glass Stopcock from its production facility in Ambala, Haryana, serving school and college laboratories, research institutes and industrial buyers across India and export markets that have recently included Angola, Mozambique and Zambia — part of a wider base of enquiries from across Southern-Central Africa.

Quick answer: This is a Gilson-pattern separating funnel fitted with a solid glass key stopcock and supplied with a PE stopper, used for liquid-liquid extraction and immiscible-layer separation. It is available in six capacities from 50ml to 2000ml, with bore sizes of 2.5mm, 4mm or 6mm.

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.
