What is the cylinder?
A graduated cylinder (French: éprouvette graduée, Spanish: probeta, English: graduated cylinder, German: Messzylinder)is a common measuring device used to measure the volume of liquids in the laboratory. Read volume. The maximum measuring volume is from several milliliters to several liters. There are scales printed on the wall of the cylinder from bottom to top,and the graduated cylinders of different specifications have different graduation values. Mainly made of glass, but also partly made of plastic. The purpose is to quantitatively measure the liquid by volume, but it is not allowed to mix reagents and carry out chemical reactions in the graduated cylinder. Measuring cylinders can be divided into two types: ordinary measuring cylinders and plugged measuring cylinders. |

Usage:
Graduated cylinders are often used to measure the volume of liquids. Compared to beakers and flasks, graduated cylinders can accurately measure the volume of liquids, but pipettes can measure more accurately. [2] When quantitative experiments are performed, higher precision volumetric flasks or pipettes are used. Graduated cylinders can also sometimes be used to measure the volume of solids by the displacement method.It must be cleaned before use. After drying, when injecting the solution, inject the solution to the appropriate scale line lower than the required volume, and use a plastic-tip dropper to adjust the volume. The solution is poured out of the barrel slowly through the mouth, and finally the mouth of the barrel is brought into contact with the wall of the receiver to remove the last of the solution. [3] Sometimes the measuring cylinder is not completely dry before use, you can dry it with absorbent paper, the steps are: take a piece of absorbent paper longer than the measuring cylinder, fold it several times until it can be inserted into the measuring cylinder, then insert the measuring cylinder, move it up and down several times to Absorb liquid from the inner surface of the graduated cylinder. Don't try to use compressed air to dry the graduated cylinder, the water doesn't evaporate very quickly, and the compressed air has a small amount of oil in it. |

Reading:
There are single scale type and double scale type of graduated cylinder, the former is more common. The single-scale graduated cylinder scale value increases from bottom to top, and the volume of the liquid injected into the graduated cylinder can be read. The double-scale graduated cylinder adds a series of scales with increasing numerical values from top to bottom, which can read the volume of the liquid injected into the graduated cylinder and the volume of the liquid poured out of the graduated cylinder. The graduated cylinder does not have a zero scale line, and the bottom scale is discontinuous, that is, the scale of the graduated cylinder does not start from zero.When reading, the measuring cylinder should be placed on a horizontal table, keeping the sight level, and reading the scale corresponding to the bottom end of the concave liquid surface or the top end of the convex liquid surface. [4] If you look up the reading, the result will be smaller than the actual value; if you look down, the result will be larger than the actual value. |
