Graduated cylinder

A tall, narrow vessel marked with volume graduations, used to measure liquid volumes. Its shape allows finer volume readings than many beakers or flasks.

Parallax: An apparent shift in an object's position when viewed from different angles. Viewing the graduations above or below eye level shifts the apparent meniscus position.
Volume: The amount of three-dimensional space occupied by a substance or object. A graduated cylinder measures liquid volume rather than mass or length.
Analytical chemistry: The branch of chemistry concerned with identifying substances and measuring their amounts. Cylinders provide routine volume measurements during solution preparation and analysis.
Beaker: A wide-mouthed laboratory vessel used for holding, mixing, and heating liquids. Beakers are easier to mix in, but their volume markings are generally less precise.
Laboratory glassware: Glass vessels and instruments designed for scientific experiments and measurements. Graduated cylinders are one standardized form of laboratory glassware.
Calibration: The comparison of an instrument’s readings with known standards to assess or correct its accuracy. Calibration determines how closely the marked volumes match actual contained or delivered volumes.
Milliliter: A unit of volume equal to one-thousandth of a liter. Cylinder graduations commonly express liquid volume in milliliters.
Solution: A homogeneous mixture in which one or more solutes are dissolved in a solvent. Cylinder-measured volumes are often transferred when preparing or diluting solutions.
Erlenmeyer flask: A conical laboratory flask with a narrow neck, used for mixing and heating liquids. Its shape supports swirling and reduces splashing, while its markings are not precise measuring scales.
Metric system: A decimal system of measurement based on units including the meter, liter, and gram. Metric units made cylinder graduations straightforward to standardize and compare.
