A beakerflask, a common glass instrument in chemical laboratories, is a titration reactor with a triangular longitudinal section made of hard glass. The small mouth and the large bottom are conducive to the sufficient reaction and the liquid is not easy to splash when the titration process is oscillated.
What can a conical flask do?
PC Conical Flask

Erlenmeyer flasks are generally used in titration experiments. In order to prevent the titrant from splashing out of the bottle when it drops, causing experimental errors, the bottle was stirred on a magnetic stirrer. You can also hold the neck of the bottle with your hand and shake it with your wrist to stir evenly. It can also be used to contain reactants, quantitative analysis, and reflux heating, and its shape makes it ideal for these jobs. In addition to being convenient to add a stopper, its long neck can also slow down the loss during heating and avoid chemical spills; as for its flat and wide bottom, it allows the conical flask to hold more solution and facilitates stirring with a glass rod. And allow the Erlenmeyer flask to lay flat on the table.
Can the conical flask be heated?
No, you need to add asbestos mesh
(1) What can be directly heated: test tubes, crucibles, evaporating dishes, combustion spoons
(2) Heated with asbestos mesh: beaker, flask (round bottom, flat bottom), conical flask
(3) Can not be heated: gas collection bottle, reagent bottle (wide mouth, narrow mouth), Kip generator, drop bottle, I suggest that the conical bottle should be heated with a water bath. Heat the conical flask in a beaker, put an appropriate amount of water in the beaker to suspend the conical flask, place the beaker on the asbestos mesh, and then heat the asbestos mesh with an alcohol lamp.
