A graduated cylinder is a type of glassware used primarily for the measurement of liquids. It features a tall cylindrical body with graduations on the side, with a larger diameter disk at the bottom for stability. The top of the cylinder may or may not have a lip, but generally has a pour spout. Graduated cylinders are typically made of glass or plastic, and are available in many sizes.
An Erlenmeyer flask, in contrast, features a cone-shaped body that tapers inward to a cylindrical neck with a small lip (but no pour spout). These flasks are typically used for mixing, because they can be "swirled" by hand with little danger of spillage, and for heating, because they can be clamped to a bench stand and have a large amount of surface area at the base to transfer heat to the solution contained within. Erlenmeyer flasks generally have gradations on the side (the tapered part, but not on the neck), but are not as finely graduated as are graduated cylinders.

ReneA graduated cylinder is a tall, cylindrical container used to measure liquid volume accurately, typically with graduated markings along its side. An Erlenmeyer flask is a conical-shaped container with a narrow neck, commonly used for mixing, heating, and storing liquids. Erlenmeyer flasks are not typically used for precise volume measurements like graduated cylinders.

What is the difference between a test tube and a graduated cylinder?
A test tube is a cylindrical container used for holding small amounts of liquid or solids for testing or mixing. A graduated cylinder is a tall, narrow cylinder with volume markings used to measure the volume of liquids. The main difference is that a graduated cylinder is used for precise volume measurements, while a test tube is for general purposes.
What is the difference between a balance and graduated cylinder?
A balance is used to measure the mass of an object, while a graduated cylinder is used to measure the volume of a liquid. Balances typically use a scale to determine weight, while graduated cylinders have volume markings along the side for measurement.
What is the difference between balance and graduated cylinder?
A balance is used to measure the mass of an object by comparing it to known weights, while a graduated cylinder is used to measure the volume of a liquid. The balance provides a quantitative measure of mass in grams, while the graduated cylinder provides a quantitative measure of volume in milliliters.
What is the difference between pipette and graduated cylinder?
A pipette is a more precise measuring tool used for transferring small volumes of liquid accurately, while a graduated cylinder is used to measure larger volumes. Pipettes typically have a finer scale for precise measurements, while graduated cylinders are suitable for general volume measurements.
Why does a concave meniscus form when water is in a graduated cylinder?
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
