Answer: Cylindrical graduate The most accurate
device for measuring volume of liquids is the graduated cylinders or
cylindrical graduate. This is a thin glass tubes that provide straightforward
reading of liquids and in order to attain the correct measurement, the liquid
must be pour down at the center of the graduate especially for viscous liquids
and the final volume must be determined by aligning the bottom of the meniscus
with the desired graduation mark. For densely colored or opaque liquids, the
top of the meniscus should be read.
