This video demonstrates proper technique for reading a graduated cylinder in a chemistry lab.

How to read a graduated cylinder in chemistry. Add your liquid to the graduated cylinder. It is a narrow cylindrical form. Measure so that the line you are reading is even with the center of the meniscus.

With larger graduated cylinders, such as a 100 ml graduated cylinder, the printed numbers are 10, 20, 30, etc., so you can read xx.x ml. Reading burets and mohr pipets. Technique for reading a graduated cylinder (2 of 2) !

Most of the chemicals used in a laboratory are liquid solutions and to ensure that they are used in the right quantities or proportions, they need to be measured out. The top of the cylinder should be level with your eye. The reader should always read the cylinder markings where the bottom of the meniscus lies i.e.

Function graduated cylinder science struck. A graduated measuring cylinder with a plastic stopper. Read the graduated cylinder to one decimal place greater than the markings show.

For water and most liquids, this is the bottom of the meniscus. Divide this number by two. Bend down so you are eye level with the meniscus line, the line that is.

If it is not, you need to adjust the height of your eye. Set the meniscus to the required mark (read at eye evel!) the wall of the cylinder must not be wetted above the mark. Plastic graduated cylinders are used because the meniscus of liquids in plastic graduated cylinders are relatively flat.
