Which instrument is commonly used to measure the volume of liquids accurately?

The measuring cylinder is the instrument that is commonly used for accurately measuring the volume of liquids. It is specifically designed with a scale that allows for precise readings of liquid volume, making it suitable for scientific experiments where accuracy is essential. The shape of the measuring cylinder, typically a tall and narrow design, minimizes meniscus error—the curvature of liquid in the container which can affect measurement accuracy.

A beaker, while capable of holding liquids, is not as accurate as a measuring cylinder due to its wider shape and less precise graduation marks. It is generally used for mixing or holding liquids rather than accurate measurements. A pipette can provide precise measurements as well, but it is typically used for transferring specific volumes of liquid rather than measuring larger volumes directly. A microscope is not used for measuring volumes at all; it is designed for magnifying small objects to be viewed clearly under light.
