Common Uses:
- Liquid-Liquid Extraction: These stopcocks are commonly used in liquid-liquid extraction processes in separatory funnels. They allow for the separation of immiscible liquids based on their different densities.
- Chemical Synthesis: In chemical synthesis, these stopcocks facilitate the separation of layers during reactions involving multiple phases.
- Purification Processes: Separatory funnels with these stopcocks are employed in purification procedures to separate impurities or by-products from the main reaction mixture.
- Analytical Chemistry: They are used in analytical chemistry for sample preparation, allowing the separation of analytes from interfering substances.
- Teaching and Research: These stopcocks are used in educational settings to teach liquid-liquid extraction principles and techniques. In research, they contribute to precise separation processes.
