GRADUATED CYLINDER Meaning and
Definition
-
A graduated cylinder is a narrow, cylindrical container used in laboratory settings to accurately measure the volume of liquids. It is typically made of glass or plastic and is calibrated with marking lines along its vertical length, allowing for precise measurements.
The design of a graduated cylinder consists of a vertical tube with a flat base and a spout. The tube is marked with evenly spaced lines, each representing a specific volume division, which are engraved or printed onto the surface of the cylinder. These markings are typically measured in milliliters (ml) or cubic centimeters (cc).
To measure a liquid's volume using a graduated cylinder, the cylinder is placed on a flat, level surface. The liquid is carefully poured into the cylinder, ensuring that the bottom of the meniscus (curved surface of the liquid) aligns with one of the calibration lines. The volume reading is determined based on the closest line or the bottom of the meniscus, depending on the specific instructions or conventions of the laboratory.
Graduated cylinders are widely used in various scientific disciplines, including chemistry, biology, and physics. They offer a higher level of accuracy compared to other common measuring instruments, such as beakers or flasks, due to their precise calibration markings and narrow shape, which reduces errors caused by parallax. Graduated cylinders are essential tools for conducting experiments, making solutions, and measuring liquid volumes in a controlled and precise manner.

Etymology of GRADUATED CYLINDER
The word "graduated" in "graduated cylinder" comes from the Latin word "gradus", meaning "step" or "degree". The term "graduated" in this context refers to the markings or lines on the cylinder that indicate specific measurement levels or increments. This allows for precise and accurate measurement of liquids.
The word "cylinder" comes from the Latin word "cylindrus", meaning "a roller or roller seal". It originally derives from the Greek word "kulindros", which denoted a cylindrical roll or tube-shaped object. In the case of a graduated cylinder, the term refers to its long, cylindrical shape.
