Volumetric flasks are a must have for any chemistry lab to accurately manufacture or mix standard solutions. For solutions prepared by weight/volume ratios, a volumetric flask will fit on a standard triple beam or digital balance. They can also be used to compliment your kitchen as an oil or vinegar dispenser.
