12. Reading a Graduated Cylinder A graduated cylinder is an instrument used to measure small amounts of liquid. The scientists use this cylinder to measure liquid volume. There are many sizes of graduated cylinders. Some measure 1,000 milliliters (mL) or 1 liter (L). Some measure 500 milliliters (mL). Some measure only in milliliters (mL). The lines on the graduated cylinder are called graduations. The liquid usually curves up the side of a graduated cylinder. To achieve an accurate reading, it is important to remember to read the measurement at the lowest point or the bottom of the curve. This low point is called the meniscus.
