Laboratory Glassware,A graduated cylinder (measuring cylinder or graduated glass) is a glass instrument used to measure liquid. A graduated cylinder is an instrument that measures the volume of a liquid. The specifications are expressed in terms of the maximum capacity (mL) of the energy, and commonly used are 10 mL, 25 mL, 50 mL, 100 mL, 250 mL, 500 mL, 1000 mL, and the like.
The outer wall scale is in mL, the 10 mL graduated cylinder represents 0.2 mL per small cell, and the 50 mL graduated cylinder represents 1 mL per small cell. It can be seen that the larger the cylinder, the thicker the pipe diameter, the smaller the accuracy, and the larger the reading error caused by the deviation of the line of sight.
Therefore, in the experiment, according to the volume of the solution taken, try to use the smallest gauge cylinder that can be measured at one time. Fractional metering can also cause errors. If you take 70ml of liquid, you should use a 100mL measuring cylinder.
