Execute highly efficient liquid-liquid extractions with Heathrow Scientific Glass Separatory Funnels. A foundational tool for organic chemistry, botanical oil isolation, and complex pharmaceutical synthesis, these premium funnels are engineered to flawlessly separate immiscible solvents of differing densities. The classic pear-shaped geometry maximizes the surface area of the phase boundary while tapering down to a narrow stem, allowing technicians to isolate and drain the heavier bottom layer with absolute pinpoint accuracy.Constructed from extra-thick, heavy-wall borosilicate glass, these funnels safely withstand the internal pressure buildup common during aggressive solvent shaking and outgassing. The fluid flow is meticulously controlled via a leak-proof PTFE stopcock, which requires no lubrication and will never seize or contaminate your purified extracts. Each funnel includes a tight-fitting stopper to secure volatile vapors during agitation. Available in a broad range of processing capacities from 300 mL for benchtop research up to 2000 mL for heavy industrial scale-up.
