You will find these cylinders worth the investment. All graduated glassware is read with one estimated digit, so this measurement is recorded correctly to the nearest 0.1 mL, with an understood uncertainty of ± 0.1 mL. The precision of any measurement (length, volume, or mass) is limited by the device used in the measurement.

However, note that the average value measured using the buret is significantly different from 25 mL. 25 mL graduated cylinder This graduated cylinder has white lines going completely around the cylinder to indicate odd number of mL quantities.

To utilize the data you must double click on the datatable, allowing the datatable to be editable. As you can see in the above tables, the 5 mL pipette has the lowest tolerance, and therefore the best accuracy, followed by the 50 mL burette, and the 10 mL graduated cylinder is the least accurate of the three. To a scientist, a large difference exists between a volume of 25 milliliters (mL) and 25.00 mL.

Graduated cylinders are sometimes used to measure the volume of a solid indirectly by measuring the displacement of a liquid. If a pipet is supposed to dispense 10 mL and it actually dispenses 15, 16, and 15 mL then it has high precision (because the numbers are close.) Its accuracy is way off because the average of 15.3 mL is half of an order of magnitude different than 10. Fisherbrand™ Serialized Class A Graduated Cylinders with Certificate of Calibration.
