Transferring Liquids Under an Inert Gas A simple procedure for transferring liquids under an inert gas is to use the stopper adapter A. This adapter is shown in the figure attached to the inverted bottle B in position for transferring liquid under an inert atmosphere to a dropping funnel. The steps in transferring liquids are to start a gentle flow of gas through the press~~re-equalizing dropping funnel, firmly insert the adapter A into the neck of the bottle R, quickly invert R and insert the projecting tip of the adapter A in one motion into the dropping funnel. Some liquids are sufficiently fluid to permit immediate flow into the dropping funnel. If the liquid is too viscous, gently and momentarily press the rubber stopper of adapterA onto the top joint of the dropping funnel. Gas bubbles will rise into the bottle B to equalize the pressure. (Cere should be taken that sufficient pressure does not build up in bottle R to force out adapter A. Skill may be gained by practicing with water.) The bottle B is then raised slightly to release the pressure and liquid will flow as a series of squirts into the dropping funnel. This technique has been used successfully to transfer aluminum alkyls with essentially no formation of fog.
