A volumetric flask is used to measure a very precise and accurate amount of a liquid, and is used for such when the amount is too big for a pipette or burette. It has a broad flat bottom so as to not tip over. The neck is marked (usually by a scratch or etch on the glass) at a very precise measurement. When the liquid has been added to that point (so the meniscus is on the line), it is usually accurate to within a small fraction of a percent and highly precise. |
