A closed transfer means for transferring liquid from a container to a dilution tank in measured volume including an actuating means moveable to a first position which energizes an electric pump to pump liquid from the container into a transfer tank and to a second position which energizes the pump to pump liquid from the transfer tank to the dilution tank. The actuating means is biased to a center position in which the electric pump is de-energized and the tanks and container are all isolated.
