Wide necked conical 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, put the bottle on a magnetic stirrer and stir. Hold the neck of the bottle with your hand and shake it with your wrist to stir evenly. Contains reagents, quantitative analysis, reflux heating, and its shape makes it suitable for these tasks. The long neck can also slow down the loss during heating and avoid the overflow of chemicals, in addition to the stopper, while the flat and wide bottom enables it to hold more solutions, which is convenient for glass rods to stir and conical flasks to lay flat. 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.
What are the uses of wide neck conical flasks
1. The conical flask is generally used in titration experiments. In order to prevent the titrant from splashing out of the bottle when it drips, causing experimental errors, place the bottle on a magnetic stirrer to stir. You can also hold the neck of the bottle with your hand and use your wrist Shake to mix evenly.
2. The conical flask can also be used in ordinary experiments to produce gas or as a reaction vessel. Its conical structure is relatively stable
3. The container can be heated on a water bath or an electric stove
Precautions for use
(1) The injected liquid does not exceed 1/2 of its volume, and it is easy to cause splashing if too much.
(2) Use asbestos mesh when heating (except electric furnace heating).
(3) The outside of the wide neck conical flask should be wiped dry before heating.
(4) After use, it needs to be cleaned with detergent, dried, and stored in a dry container.
(5) Under normal circumstances, it cannot be used to store liquids.
(6) Rotate in the same direction when oscillating
