How to Use Graduated and Mixing Cylinders

Graduated cylinders

Graduated cylinders, class A and B are measuring instruments that are calibrated to contain (TC, In), therefore, they indicate the exact volume added.


  • Fill with liquid.
  • Set the meniscus to the required mark (read at eye evel!)
  • The wall of the cylinder must not be wetted above the mark.
  • The indicated volume is the amount of liquid contained.

Note: Graduated cylinders are used as measuring instruments that are calibrated to deliver (TD, Ex). Measurements with water showed that the dispensed volume is reduced by approximately the amount of the error limit of the graduated cylinder due to the residue amount from wetting. Prerequisite: The liquid is slowly dispensed in one portion, and to finish delivery of the liquid the cylinder is held at an incline for a further 30 s.

Mixing cylinders

The mixing cylinder is calibrated to contain (TC, In), just as the graduated cylinder, and are supplied with a ground glass joint and stopper.

Mixing cylinders can be used in the preparation of standard solutions and dilutions, the same as volumetric flasks.

  • After portions of various liquids have been measured out, these can then be mixed by shaking directly in the mixing cylinder.

Note: When two liquids are mixed, a volume change may occur.
