Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids. Similar to cylinders, beakers are graduated with volume measurements.
In that case, why is a graduated cylinder more accurate than a beaker? The volume marks on a beaker are only approximate values, and therefore only provide whole numbers. Overfilling the flask above the graduation mark ruins the volume measurement. In this case, the content inside the volumetric flask should be discarded.
A pipette bulb should be used to withdraw and deliver liquids when using a pipette. The volumetric flasks are small in size,so measuring a large volume by a volumetric flask is fairly difficult. Either a very big flask is needed or we have to measure the large volume into smaller parts. Erlenmeyer flasks are great for mixing chemicals since they have a wide base and can be swirled around without spillage. Since the base is wide, there is less danger of the liquid rising to the top and spilling out.
The Erlenmeyer filter flask also has the advantage of avoiding tipping over. Unlike measuring cylinders and even breakers, its wide base keeps it from spilling. The narrow mouth of the flask in contrast to its wide base lowers the center of gravity. This is why samples or mixtures are not generally stored in beakers. Due to the narrow mouth, the conical flask is also used for filtering different samples with filter paper.
It can also be used to contain titrates. These features make it great for re-crystallization. These features also make the flask ideal to perform boiling reactions. The conical nature of the flask allows for the solvent to condense on its body. This prevents solvent loss. These reactions have to be controlled however. Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck.
Flasks can be used for holding and measuring solutions, as well as for chemical reactions and phase changes heating, cooling, etc. Flasks are normally the site of chemical reactions, for the reaction can take place in the large vessel and have low risk of spilling due to the long, narrow neck of the flask.
Furthermore, flasks have the ability to be capped or corked, therefore solutions can be held for long periods of time without risk of spilling. Beakers, on the other hand, are cylindrical containers with a flat bottom and a spout on top.
These are also used when performing experiments, to hold various liquids for either mixing or disposal.
