Separating Funnel 60ml

Separating Funnel 60ml

A 60ml separating funnel (or separatory funnel) is a small-capacity, pear-shaped laboratory glassware item used for liquid-liquid extraction to separate two immiscible liquids (e.g., oil and water) based on density. It features a PTFE stopcock for draining the bottom layer and a top stopper to vent vapor pressure.

Key Uses and Functions:
Liquid-Liquid Extraction: Separates components of a mixture by partitioning them into two immiscible solvent phases.
Purification: Used to wash organic layers with water or aqueous solutions, such as removing impurities or residual solvents.
Small-Scale Reactions: Ideal for analytical chemistry or organic synthesis applications requiring smaller sample volumes.
Controlled Separation: Allows precise, safe separation of liquids by draining the denser bottom layer through the stopcock.

Features:
Material: Borosilicate glass.
Components: Pear-shaped body, PTFE (Polytetrafluoroethylene) stopcock, and stopper.
Capacity: 60ml, suitable for small-scale experiments.

Key Applications
Separation of Immiscible Phases: The main function is to physically separate two distinct liquid layers, such as an organic solvent (e.g., ether, hexane) and an aqueous (water-based) solution.
Liquid-Liquid Extraction: This is a core technique in organic chemistry where a compound is transferred from one solvent to another to isolate or purify a desired substance from a mixture.
Purification: It is used to remove impurities from chemical solutions or reaction products by washing the desired phase with another solvent, a common step in organic synthesis and pharmaceutical preparations.
Sample Preparation and Analysis: In analytical and environmental laboratories, small separating funnels help in preparing samples by extracting specific pollutants or components from water or soil samples for analysis.
Small-Scale Reactions: The controlled flow via the stopcock allows for the slow, dropwise addition of reagents to a reaction mixture, which is crucial for reactions that are sensitive to rapid addition.

Principle of Operation
The separating funnel operates on the principle that immiscible liquids will form distinct layers when allowed to settle, with the denser liquid at the bottom and the lighter liquid floating on top. The stopcock at the bottom allows for the precise, controlled draining of the lower layer, leaving the upper layer in the funnel and facilitating clean separation
