6810-Separating Funnel, Globe (Long Stem) with PTFE Plug, ASTM

• With Glass Stopper & PTFE Plug Stopcock

Here are some common uses for a separating funnel with a globe shape, long stem, and PTFE plug in accordance with ASTM standards:

1. Liquid-Liquid Extraction:
   • Separating funnels are commonly used for liquid-liquid extractions where two immiscible liquids (usually water and an organic solvent) are separated based on their densities.
2. Sample Partitioning:
   • In analytical chemistry, separating funnels with PTFE plugs are used for partitioning samples between two phases to isolate specific compounds or analytes.
3. Purification Processes:
   • Separating funnels are employed in various purification processes, where impurities or unwanted substances are separated from the desired product through liquid-liquid extraction.
4. Phase Separation:
   • The PTFE plug in the separating funnel allows for precise control of the flow, aiding in the separation of two phases without mixing.
5. Chemical Synthesis:
   • In chemical laboratories, these separating funnels are used in the synthesis of compounds, allowing for the separation of reaction mixtures into organic and aqueous phases.
6. Solvent Recovery:
   • Separating funnels can be used in processes where solvents need to be recovered from reaction mixtures. The plug helps in draining and collecting specific layers.
7. Sample Cleanup:
   • Prior to analysis, separating funnels are used for cleanup procedures, removing unwanted substances or interfering compounds from a sample matrix.
8. Fractionation:
   • These funnels are useful for fractionating mixtures, separating components based on their solubility in different phases.
9. Analytical Chemistry:
   • Separating funnels are a common tool in analytical laboratories for sample preparation, allowing for the extraction and separation of analytes.
10. Research and Development:
    • In research settings, separating funnels with PTFE plugs are used for various experimental procedures requiring liquid-liquid extractions and phase separations.
