The 1000mL Separating Funnel (Pyrex India) is a premium-quality, laboratory-grade glass instrument designed for liquid–liquid extraction, solvent separation, and chemical analysis. Manufactured from borosilicate glass (3.3 grade), it offers superior thermal and chemical resistance, ensuring accuracy and durability in demanding laboratory environments.

With a conical pear-shaped body, a PTFE stopcock, and a standard ground-glass joint, this separating funnel provides smooth and precise liquid flow control. As a result, it is ideal for separating immiscible liquids such as oil and water or for conducting solvent extraction in organic chemistry and biochemistry laboratories.

Moreover, its clear glass body allows easy observation of phase separation, while the graduated markings help measure volume accurately during experimental procedures.
