Graduated cylinders are used to measure specific volumes of
liquids. The glass cylinder has etched marks to indicate volumes,
a pouring lip, and quite often, a plastic bumper to prevent breakage.
Determine the volume contained in a graduated cylinder by
reading the bottom of the meniscus at eye level. Read the volume
using all certain digits and one uncertain digit. Certain digits
are determined from the calibration marks on the cylinder. The
uncertain digit (the last digit of the reading) is estimated.
Several examples are shown below:
|10mL graduated cylinder (6.62 mL)
||100mL graduated cylinder (52.7 mL)
|25mL graduated cylinder (11.5 mL)|
Examine the meniscus below and determine a the volume of liquid contained in the graduated cylinder.
