Beaker and Graduated Cylinder are two standard apparatuses that you will find in the laboratory. Although both are used to get accurate results when measuring solutions, there are, however, some differences between the two. A beaker is a flat bottomed cylindrical vessel, with a lip, which can be used for mixing solutions.
On the other hand, a graduated cylinder is also an apparatus used when measuring the volume of liquids and solutions. Another difference is that a graduated cylinder is narrow, whereas a beaker is wide, plus it has a lip for easy pouring of liquids. The pouring lip in beakers can also be found in graduated cylinders.
Mostly, beakers are made with glass, whereas graduated cylinders can as well be made with polypropylene or polymethyl pentene. Beakers are used when performing experiments that involve the mixing of solutions. Beakers can also be used to heat solutions, whereas graduated cylinders are used mostly for measuring liquids and solutions.
