Dropping funnel with tap, Nairobi Industrial Area

A dropping funnel with a tap is a laboratory apparatus typically made of glass, featuring a conical body with a narrow neck and a stopcock at the bottom. This design allows for controlled dispensing of liquids, making it ideal for gradual addition of reagents in chemical reactions. The tap provides precise flow control, ensuring that substances can be added slowly to avoid sudden reactions.

The funnel is often used in titration processes, mixing reactants, and performing extractions, and it can be placed in cooling baths for temperature control during reactions. Its ability to facilitate meticulous liquid transfer makes it a crucial tool in organic synthesis and other laboratory applications.
