According to GCSE Science, a burette is calibrated to give readings that are accurate to 0.2 cubic centimeters. On the other hand, a pipette has a bulge in the middle, and is calibrated with a filling line that gives a precise volume of the substance it contains at the particular point. A clean volumetric pipette gives a reading to the precision of 0.01 milliliters, according to Green River Community College.
A burette is a long tube made of glass that has a tap at its bottom end, GCSE Science explains. One type of burette is graduated along its length with marks that are 2 cubic centimeters apart. It has additional smaller marks in between that give it its level of accuracy, showing the total volume of a substance at each mark.
As Titrations explains, single volume pipettes belong to a category of volumetric glass that measure predetermined volumes of a solution. When a pipette is emptied, it delivers the exact volume of a solution it is designed to hold. The accuracy of a pipette is not affected by remnants of a substance on its walls and in the tip. The measuring tubes not only exhibit high levels of precision but also allow for repeatability of measurements.
