Applications and Experiments for the Gilson Glass-Stopcock Separating Funnel
With this funnel, students can partition a solute between water and an organic solvent, then draw off the lower layer through the glass stopcock. It fits extraction and separation experiments in higher-secondary chemistry, undergraduate organic labs, pharmacognosy practicals and routine sample preparation in testing laboratories.
- Class 12 chemistry: separating a mixture of two immiscible liquids, with the funnel set in a ring of a Laboratory Stand.
- B.Sc. chemistry: determining a distribution (partition) coefficient, with each layer run into Beakers, Tall form, Without Spout for titration.
- B.Pharm pharmacognosy: extracting plant constituents into a solvent layer and keeping it in a Flask Erlenmeyer with Screw Cap.
- Testing labs: washing and drying organic extracts before analysis.
A glass key seals well with a thin film of stopcock grease; wipe it and the barrel clean after use so the key does not seize.
Standard Scope of Supply
You receive the Gilson funnel with its solid glass stopcock in place, in the bore and capacity you specify, with a PE stopper available. Stopcock grease, stands, rings and holders can be quoted as separate lines on the same quotation if your bench needs them.
Packing, MOQ and Lead Time
Our team can quote one funnel or a class set in several capacities for a chemistry laboratory. The quotation spells out the packing, delivery time and price for your quantity, and holders or other items from our stock as a laboratory glassware supplier in India can be added on the same page.
Holding an Importer-Exporter Code, Science Lab Supplies as a registered exporter can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt.

Frequently Asked Questions
Why choose a solid glass stopcock?
A glass key is the traditional choice for teaching labs: it is inert to most solvents and matches the glass barrel exactly. It needs a light grease film, unlike a PTFE key.
Is there a PTFE version of this funnel?
Yes. The Separating Funnel Gilson PTFE Stopcock is the same Gilson pattern with a PTFE key, made in the same 2.5, 4 and 6 mm bores and the same 50 ml to 2000 ml capacities.
What capacities and bores can be ordered?
Capacities are 50, 100, 250, 500, 1000 and 2000 ml, and bores are 2.5, 4 and 6 mm. Any capacity can be quoted with any bore, so name both on your enquiry.
Who supplies this Gilson funnel?
Educational institutions, laboratories and tender contractors can obtain a quotation for it from Science Lab Supplies in Ambala, India, either on its own or grouped with other separating funnels.
