Gradual cylinder, measuring cylinder or graduated glass is a kind of glass instrument used to measure liquid.A measuring cylinder is an instrument for measuring the volume of a liquid.Specifications are expressed in the maximum capacity (mL) that can be measured, commonly used 10 mL, 25mL, 50 mL, 100 mL, 250 mL, 500 mL, 1000 mL and so on.The outer wall markings are in mL, 0.2 mL for each 10 mL measuring cylinder and 1mL for each 50 mL measuring cylinder.
It can be seen that the larger the cylinder, the diameter of the tube will be larger, the accurate will be less, and the reading error caused will be greater by the line of sight deviation. Therefore, according to the volume of the solution taken in the experiment, the smallest measuring cylinder that can be taken at a time should be selected as far as possible. Fractional measurements can also cause errors. If measure 70ml liquid, should choose 100mL cylinder then. Apply to laboratory,school,hospital,science research etc.
