Verified step by step guidance1
Understand that laboratory materials vary in their precision and purpose when measuring liquids.
Recognize that an Erlenmeyer flask and a beaker are primarily used for mixing, heating, or holding liquids, but they are not designed for precise volume measurements.
Know that a test tube is used for holding small amounts of liquids during experiments, but it does not provide accurate volume measurements.
Identify that a volumetric pipette is specifically designed to measure and transfer a precise volume of liquid, often with very high accuracy.
Conclude that among the options given, the volumetric pipette is the correct laboratory material used to accurately measure liquids.
