• With Glass Stopper & PTFE Plug Stopcock

Here are some common uses of a Squibb Separating Funnel with a short stem and PTFE plug:

1. Liquid-Liquid Extraction:
   • The primary and most common use of a Squibb Separating Funnel is for liquid-liquid extraction. It allows for the separation of immiscible liquids or the extraction of specific compounds from a mixture.
2. Sample Preparation for Analysis:
   • Laboratories use Squibb Separating Funnels to prepare samples for analysis by separating different components or isolating specific fractions for further testing, such as chromatography or spectroscopy.
3. Purification Processes:
   • Squibb Separating Funnels are employed in laboratories for purifying substances by removing impurities or unwanted components through liquid-liquid extraction.
4. Solvent Recovery:
   • After a chemical reaction or process, these funnels can be used to recover solvents or valuable components by separating them from the reaction mixture.
5. Phase Separation:
   • Squibb Separating Funnels are essential for phase separation, ensuring that different layers, such as organic and aqueous phases, can be cleanly and precisely separated.
6. Fractionation:
   • Laboratories use these funnels for fractionation, allowing for the collection of distinct fractions based on differences in solubility or other properties.
7. Removal of Impurities:
   • Laboratories use Squibb Separating Funnels to remove impurities or unwanted substances from reaction mixtures or samples.
8. Extraction of Specific Compounds:
   • In organic synthesis or analytical chemistry, these funnels are used to selectively extract and separate specific compounds from a mixture.
9. Biological Sample Processing:
   • Squibb Separating Funnels may be used in biological laboratories for processing and extracting specific compounds from biological samples.
10. Teaching and Demonstrations:
    • Educational laboratories often use Squibb Separating Funnels to teach students about liquid-liquid extraction techniques and the principles of phase separation.
11. Quality Control Processes:
    • In industries where quality control is crucial, these funnels may be used for extracting and isolating specific components for analysis.
12. Research and Development:
    • Squibb Separating Funnels are used in research laboratories for various experiments and processes that involve the extraction or separation of substances.
13. Environmental Testing:
    • Laboratories involved in environmental testing may use these funnels for extracting pollutants or specific compounds from environmental samples.
