the quantity which the pipette could hold was determined by the size from the bore (within diameter) of the tube. within the nineteenth century, much more exact pipettes have been formulated that applied a calibrated scale over the aspect with the pipette to evaluate the volume.
Calibration of pipettes is the entire process of ensuring that the quantity of liquid dispensed or aspirated by a pipette is exact and reliable.
