Make sure the cylinder is on a flat surface.
. 2) Determine the volume of the liquids in the following cylinders: The formula for the volume of a cylinder is height x π x (diameter / 2) 2, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius 2.Visual in the figure below: First, measure the diameter of the base (usually easier than measuring the radius), then measure the height of the cylinder. Two classes of accuracy exist for graduated cylinders. Simplify volume readings: liquid in plastic cylinders doesn’t form a meniscus, and level liquid avoids confusion and errors. Confirm that the tube is clean and dry. The error, give or take 0.1 mL, must be included too. Polypropylene (PP) is easy to repeatedly autoclave; however, autoclaving in excess of about 121 °C (250 °F) (depending on the chemical formulation: typical commercial grade polypropylene melts in excess of 177 °C (351 °F)), can warp or damage polypropylene graduated cylinders, affecting accuracy.[1]. The main reason as to why the reading of the volume is done via meniscus is due to the nature of the liquid in a closed surrounded space. Graduated cylinders are thin glass tubes used to measure the volumes of liquids. To properly measure the volume of a liquid in a graduated cylinder you must be at eye-level and read the bottom point of the meniscus. They measure volumes accurately if the reading technique is correct. the word stands for mILLILITER Reply.
