A separating funnel, also known as a separation funnel, is a piece of laboratory glassware used to separate immiscible liquids, meaning liquids that do not mix, like oil and water. This one has a PTFE stopcock, a PP stopper and a drip tip in a 24/29 ground joint.

In liquid-liquid extractions, a mixture is separated into two distinct liquid phases based on density. The denser liquid settles at the bottom. A stopcock (a valve at the bottom) allows the user to drain the lower layer while the upper layer remains in the funnel, and by carefully opening and closing it the two liquids can be separated cleanly.

Key components

  • Funnel body: the main container that holds the liquids.
  • PTFE stopcock: a valve made from polytetrafluoroethylene (PTFE), also known as Teflon. PTFE has excellent chemical resistance and durability, so it suits a wide range of reagents and liquids.
  • Stopper: a polypropylene (PP) plug at the top to seal the funnel during shaking and mixing. PP is a thermoplastic polymer known for its strength, flexibility and resistance to many chemicals, acids and bases. It is also lightweight and can withstand high temperatures.
  • Socket: the ground glass joint enables the funnel to be sealed during use, which prevents evaporation or leakage of liquids. A 24/29 joint on the funnel will fit a 24/29 joint on a stopper, condenser or other glassware. The first number, 24, indicates the diameter of the larger end of the joint in millimetres. The second number, 29, indicates its length in millimetres.
  • Drip tip and cone: allows for the controlled addition of liquids to another piece of glassware, like a flask, via a ground glass joint. This setup enables a slow, dropwise addition of reagents, which matters for reactions that are sensitive to rapid addition. In some setups, like distillation, a drip tip can help prevent the backflow of vapours into the receiving flask.
