Thistle Funnel

thistle funnel is a piece of laboratory glassware consisting of a long, narrow shaft (tube) with a reservoir and funnel-like section at the top. It is primarily used by chemists to add small volumes of liquids or powders to a precise position within an existing system or apparatus. The long stem allows accurately directed and controlled pouring, minimizing splashing or spilling, and can be inserted through small openings like those in stoppers. Thistle funnels are commonly made from borosilicate glass for chemical resistance and thermal stability, and they may be found with or without taps. They are essential in processes requiring the careful addition of reagents in experiments and small-scale reactions
