Dropping Funnel Cylindrical Glass Stopcock is manufactured from heat-resistant, durable borosilicate glass in accordance with DIN/ISO standards, ensuring long-term reliability in laboratory applications. The cylindrical body is equipped with clearly printed graduation marks, enabling accurate measurement and controlled delivery of liquids during experimental procedures.

Volume graduations and inscriptions are printed with white enamel, providing excellent visibility and resistance to chemical exposure. The funnel features perfectly ground NS necks with smooth interior surfaces, allowing secure, leak-free connections with standard laboratory glassware.

Its thick-walled construction and reinforced rim significantly reduce the risk of breakage during washing, handling, and transportation. The product is supplied with a precision glass stopcock and a P.E. stopper, allowing smooth and accurate regulation of liquid flow.

This cylindrical dropping funnel is widely used in chemistry laboratories, research facilities, and educational institutions for reagent addition, synthesis reactions, and analytical setups where precise flow control is essential.
