The Separating Funnel with Teflon (PTFE) stopcock is essential laboratory glassware used for liquid-liquid extraction and phase separation of immiscible liquids. It is widely employed in chemical analysis, pharmaceutical research, organic synthesis, and academic laboratories.
Product Description
The Separating Funnel With Teflon Stopcock is a precision laboratory glassware instrument designed for accurate and efficient liquid–liquid separation. To begin with, it is manufactured from premium borosilicate glass, which offers excellent resistance to heat, chemicals, and thermal shock. Because of this, the funnel performs reliably during repeated laboratory operations.
In practical laboratory use, the Teflon stopcock provides smooth, precise, and leak-free flow control. Consequently, phase separation becomes easier and more controlled, especially when working with immiscible liquids. At the same time, the chemically inert nature of Teflon prevents interaction with aggressive solvents, thereby ensuring sample purity.
From a functional standpoint, the pear-shaped body promotes clear phase separation. As a result, users can easily identify and drain lower layers without disturbing the upper phase. Additionally, the standard TS joint ensures a secure and stable connection with other laboratory glassware. Therefore, assembly remains quick and efficient during routine workflows.
During extended laboratory use, durability plays an important role. For this reason, the smooth internal surface supports easy cleaning and minimizes residue buildup. Moreover, the robust construction allows frequent handling without compromising safety or accuracy. Hence, the funnel remains suitable for both routine and advanced laboratory applications.
In conclusion, the Separating Funnel With Teflon Stopcock combines chemical resistance, precise control, and long-term durability. Thus, it is widely preferred in educational institutions, research laboratories, pharmaceutical facilities, and chemical industries that require reliable and consistent separation results.
