Differences
No significant lexical differences. 'Tap' may occasionally replace 'stopcock' in UK lab parlance, but the term 'separating funnel' is standard in both.
Connotations
Purely technical, scientific, and neutral in both regions.
Frequency
Equally rare outside of chemistry/engineering/laboratory contexts in both the UK and US.

FAQ
Frequently Asked Questions
No, it is a very low-frequency, specialised term used almost exclusively in chemistry and laboratory contexts. The average native speaker may not know it.
A normal funnel is a simple cone for transferring liquids or powders into containers with small openings. A separating funnel is a complex piece of glassware with a stopcock (tap) at the bottom and a stopper at the top, designed to separate, not just transfer, liquids.
The mixture is poured in, the funnel is stoppered and shaken, then left to settle into distinct layers. The stopcock is then opened to drain the denser bottom layer into a separate container, effectively separating the liquids.
Rarely, but it's possible in very specific analytical writing. For example: 'The new policy acted as a separating funnel, dividing public opinion into two clear camps.' This is an extended, non-technical use.

Mnemonic
Think of a special funnel that doesn't just pour; it 'separates' liquids by letting you drain the bottom one like a tap. The name is its exact job: a funnel for separating.
Conceptual Metaphor
A TOOL FOR SORTING / A SELECTIVE GATE: Conceptualized as a device that applies a rule (density) to allow one component to pass while holding another back.
