Thistle funnel with tap, Nairobi Industrial Area

A thistle funnel with tap is a laboratory glassware tool designed for adding liquids in a controlled manner to a reaction vessel. It consists of a long, narrow stem with a wide funnel at the top (shaped like a thistle flower) and an integrated tap (or stopcock) at the base. The tap allows precise control over the flow of liquids, ensuring that substances can be introduced gradually into a container without splashing or rapid mixing. It's commonly used in titration setups, reactions where a slow addition is necessary, or when adding reagents to a system under pressure or vacuum
