Product Overview
Pressure equalising funnels have a narrow-bore glass tube from the bulb of the funnel, to just above the ground glass joint on the stem. This replaces the liquid volume lost in the bulb with the equivalent gas volume from the flask into which the reagent is flowing, and is useful when handling air-sensitive reagents in a sealed, inert-gas environment. Without this tube, or some other means to equalize the pressure between a sealed receiving flask and the bulb of the funnel, the flow of fluid from the bulb will stop.
