Separating funnels are an essential piece of laboratory glassware used to separate two immiscible liquids of differing density, most commonly during liquid to liquid extraction. By allowing the denser layer to settle to the bottom and then drawing it off through a controlled stopcock, they make it simple to isolate a target compound from a mixture with accuracy and repeatability. The tapered or cylindrical body and narrow outlet give you a clear view of the interface and precise control over exactly how much liquid is drawn off.
Hurst Scientific supplies quality separating funnels suited to routine chemistry, organic synthesis, teaching laboratories and analytical work across Australia. Whether you are extracting an organic phase, washing a solution, removing an aqueous layer or partitioning a sample before further analysis, our funnels deliver the clean, controlled flow that reliable separation depends on, helping you achieve consistent results.

Our range features cylindrical borosilicate glass separating funnels fitted with a precision glass stopcock, offering excellent chemical resistance and optical clarity so you can watch the boundary between layers form clearly. Borosilicate glass stands up to a wide variety of solvents, acids and reagents, resists thermal shock and is easy to rinse and clean between uses, making it a dependable choice for demanding extraction work.
The glass stopcock provides smooth, leak resistant control over drainage, letting you stop the flow the instant the interface reaches the tap and avoid cross contamination between fractions. Available in a convenient 100ml capacity, these funnels are well suited to small scale extractions, method development, repeat sampling and student practicals where accuracy, safe handling and durability all matter. A matching stopper keeps contents secure during shaking and venting.
