Separating Funnel with PTFE Key Stopcock
A separating Funnel with PTFE Key is used for all the liquid-liquid extractions, such as water and oil. It separates the components of a liquid solution into two immiscible solvent phases of different densities.
A separating funnel is a piece of glassware used in labs to separate two immiscible substances that are unable to mix. The PTFE key is a small, disc-shaped piece of Teflon used to stop the liquid flow from the funnel.
The separating funnel works because the two substances have different densities, so they will settle into layers based on weight. The heavier substance will settle on the bottom of the funnel, while the lighter one will float on top. Using the PTFE key to stop the liquid flow prevents the two substances from mixing again.
