Design The pressure equalizing funnel is a special type of dropping funnel. A pressure equalizing funnel is used to add exact amounts of liquid to the receiving flask slowly and smoothly. With the side narrow-bore tube, the liquid from the funnel drops smooth without having to remove the glass joint stopper. This pressure equalizing funnel is fitted with a PTFE stopcock which allows the transfer to be controlled. It's useful for adding reagents slowly.
