What is the conical flask used for? Can the conical flask be heated?
What is a conical flask? A conical flask is a titration reactor with a triangular longitudinal section made of hard glass, a small mouth and a large bottom, which is conducive to sufficient reaction, and the liquid is not easily splashed during the titration process. It is flat-bottomed and tapered, with a wide bottom and a narrow top. It has a cylindrical neck with a wider opening at the top that can be plugged with a cork or rubber stopper. There are usually several graduations on the bottle to indicate the capacity it can hold.
What is the Erlenmeyer flask used for? Erlenmeyer flasks are usually used for titration experiments. In order to prevent experimental errors caused by splashing out of the bottle when the titrant drops, the bottle was stirred on a magnetic stirrer. You can hold the mouth of the bottle with your hand and shake with your wrist to mix well. It contains reactants, quantitative analysis, reflux heating, and its shape makes it suitable for these tasks.

In addition to the long neck, you can add a stopper, which can also slow down the loss during heating and prevent chemical spills. The flat and wide bottom makes the conical flask contain more solution and facilitates stirring with the glass rod. The conical flask is flat. Put it on the table. Erlenmeyer flasks can also be used for general experiments, gas preparation or as reaction vessels. Its conical structure is relatively stable and not easy to fall.
Can the Erlenmeyer flask be heated? Erlenmeyer flasks are glass instruments commonly used in chemical laboratories. Erlenmeyer flasks cannot be heated directly. Since the bottom of the Erlenmeyer flask is flat, direct heating may cause uneven heating and cause an explosion. Erlenmeyer flasks need to use asbestos mesh when heating.
The above is what the conical flask is used for? Can the conical flask be heated? In the process of using the conical flask, it should be noted that the liquid in the conical flask should not exceed 1/2 of its volume. If there is too much, it may cause splashing, and you need to use asbestos mesh when heating (except electric furnace heating), and wipe the outside of the Erlenmeyer flask before heating.
