The Separating Funnel Squibb Glass Stopcock is a precision laboratory glassware item designed for liquid–liquid separation and extraction processes. It is manufactured from heat-resistant, durable borosilicate glass and produced in accordance with DIN/ISO standards, ensuring excellent chemical resistance, thermal stability, and long-term reliability.

The Squibb-type design allows efficient phase separation, while the perfectly ground NS neck with smooth interior ensures secure compatibility with standard laboratory joints. The funnel features clear volume graduations and inscriptions printed with white enamel, enabling accurate monitoring of liquid volumes during extraction procedures.

Its thick wall construction and reinforced rim significantly reduce the risk of breakage during washing, handling, and transportation. The product is supplied with a P.E. stopper and a glass stopcock, providing smooth flow control and precise phase discharge without contamination.

This separating funnel is widely used in chemistry, pharmaceutical, research, and educational laboratories, where controlled and reproducible liquid separation is essential.
