WebGraduated Cylinders Graduated Cylinders ACT Label A. Glass cylinder B. Plastic cylinder Plastic versus glass Nalgene plastic cylinders don't form a meniscus like glass cylinders do. You can read the liquid level straight across the graduation line. Avoid confusion and errors by using plastic instead of glass. A graduated cylinder, also known as a measuring cylinder or mixing cylinder, is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured. See more Large graduated cylinders are usually made of polypropylene for its excellent chemical resistance or polymethylpentene for its transparency, making them lighter and less fragile than glass.

WebJun 18, 2024 · When measuring liquid volumes, the graduated scale must be read from the lowest point of the curved surface of the liquid – the liquid meniscus. The graduated cylinder markings are every 1-milliliter. The correct reading is 30.0 mL. The first 2 digits 30 .0 are known exactly. The last digit 30. 0 is uncertain. WebJan 4, 2024 · Clearly, the smaller cylinder approach is more accurate (1% < 1.4%) Meanwhile, the mark scheme says that one must use the 100 ml cylinder, for the 10 ml cylinder would give a total 7*0.1/10=7% percentage uncertainty, compared to the 1.4% from the 100 ml cylinder. (1.4% < 7%) Isn't adding percentages in this way fallacious?
