The Beaker
Beakers are used to hold liquids. They cannot measure liquids accurately but they do have graduations which allow you to estimate the volume of liquid. Some beakers, those made of heat resistant glass such as Pyrex, can be heated.
Beakers come in different sizes. The maximum volume of liquid that can be held in a beaker is always written on its side.
The Test Tube
Test tubes are also used to hold liquids. Heat resistant test tubes can be heated.
When you draw test tubes you do not show the test tube rack. It is assumed that the test tubes are being supported by the rack.
The Conical Flask
The conical flask has the same properties as a beaker but it has a different shape. Because its neck is narrow a delivery tube can be fitted into it.
This means that gases which evaporate when a liquid is heated can be 'directed' to another part of the apparatus.
