Is a 10 mL or a 25 mL graduated cylinder more accurate for density measurements?
Generally speaking, manufacturing capability gives higher accuracy for larger cylinders. But accuracy is a property of individual glassware, so both cylinders would have to be tested to make a comparison. Best results would be obtained from glassware that is individually serialized and accompanied by a certificate of accuracy. Accuracy of graduated cylinders is low compared to burets and volumetric flasks. Another factor in determining density is the implied use of some device to determine weight. A balance or scale will have its own associated accuracy, and the overall accuracy of a density determination will depend on all of the measurements involved.
