Which instrument is best described as a narrow, tall container used for accurate measurement of liquid volume?

• A. Volumetric Pipet
• B. Volumetric Flask
• C. Graduated Cylinder
• D. Full-face Shield

Answer: (C)

Measuring liquid volume relies on choosing glassware whose shape and markings match the precision you need. A graduated cylinder fits the description of a narrow, tall container with graduation marks along its length, designed for reading volumes with reasonable accuracy. To read it properly, view the meniscus at eye level and read the bottom of the curve where the scale lines cross the liquid’s surface. This setup gives a reliable measurement for everyday lab tasks, offering more precision than a beaker or flask but less than true volumetric glassware. The volumetric pipet is for delivering a precise, fixed volume, not for measuring varying amounts. The volumetric flask is used to prepare solutions to a exact final volume, not to measure an arbitrary amount. The full-face shield is PPE and isn’t used for measuring liquid volumes.
