24/40 Glass Separatory Funnel with PTFE Stopcock

24/40 Glass Separatory Funnel with PTFE Stopcock

The 24/40 Glass Separatory Funnel with PTFE Stopcock is laboratory glassware used for liquid-liquid extraction and phase separation. A separatory funnel provides a controlled vessel for mixing immiscible liquid phases and then allowing them to separate by density before one phase is drained through the stopcock. The 24/40 designation identifies the standard-taper connection associated with the glassware configuration, while the PTFE stopcock provides a chemically resistant valve interface for controlled discharge.

Separatory funnels are common in analytical chemistry, organic synthesis, environmental extraction, and sample-preparation workflows. During an extraction, the sample and solvent are combined, the phases are allowed to separate, and the lower or selected phase can be withdrawn through the stopcock. Correct glassware selection depends on capacity, joint configuration, stopper arrangement, and chemical compatibility.

Key Features

• Glass separatory funnel configuration.
• 24/40 standard-taper identification.
• PTFE stopcock for controlled liquid discharge.
• Designed for liquid-liquid extraction and phase separation.
• Relevant to analytical and synthetic laboratory workflows.

Applications

This type of separatory funnel is useful for solvent extraction, sample cleanup, organic chemistry, environmental sample preparation, and other laboratory procedures involving immiscible liquid phases. The PTFE stopcock can be advantageous where chemical resistance and controlled flow are required. Before use, the user should confirm that the glassware, stopcock materials, joint dimensions, and vessel capacity are appropriate for the intended solvent system and procedure.
