Applications and Experiments for the PTFE Key Separating Funnel
The PTFE key turns smoothly without grease, so the funnel can be shaken, vented and drained repeatedly with organic solvents that would otherwise dissolve stopcock grease. That makes it a practical choice for extraction work in university, pharmacy and quality-control laboratories where clean extracts matter.
- B.Sc. and M.Sc. organic chemistry: extraction and washing of reaction mixtures.
- B.Pharm practicals: solvent extraction in pharmaceutical analysis.
- Analytical labs: liquid–liquid extraction before instrumental analysis.
- Class 12 chemistry: demonstrating separation of immiscible liquids.
Release pressure through the stopcock after every shake when using volatile solvents, and work in a well-ventilated area.
Standard Scope of Supply
The funnel is supplied with its PTFE key stopcock fitted and a PE stopper, in the bore and capacity you order. The listing does not include stands, rings or holders; a separatory funnel holder can be added to the same order.

Frequently Asked Questions
What comes with the funnel?
Each funnel has a PTFE key stopcock and a PE stopper, and its printing is in white enamel.
Which capacities and bores are offered?
Capacities are 125, 250, 500, 1000 and 2000 ml. Stopcock bores of 2, 4 and 6 mm are listed; tell us which you need for each size.
Does a PTFE key need grease?
No. PTFE seals against the glass barrel without grease, so solvents are not contaminated and the key is less likely to stick after use.
