APPROXIMATE VOLUMES - An approximate volume of a liquid can be deliverd by filling the graduated cylinder to the desired level and transferring the entire contents of the cylinder to a recieving vessel.
MORE ACCURATE VOLUMES - More accurate volumes are delivered by making an initial and final volume reading and calculating the volume delivered (by difference). An accurate final volume reading can only be made if there is liquid still in the graduated cylinder; thus, the graduated cylinder should not be emptied when the contents are transferred.
