Method of using Round Bottom Nitrogen Flas:

 

1. When using the borosilicate nitrogen flask, first wash and dry,

 

2. use aluminium foil on the balance to weigh the measured substance,

 

3. then wrap it with aluminium foil and put it into the Round Bottom Nitrogen Flask, put in sulphuric acid and heat it, so that the measured substance reacts with the sulphuric acid to form sulphuric acid hinges, and we must pay attention to the need to tilt the flask by 45% when heating.

 

4.It must be noted that the borosilicate nitrogen flask needs to be tilted at an angle of 45° so that the solution inside the flask will not be easy to explode and boil out.

 

5.Nitrogen determination, such as the use of straight device, must be added to the glass nitrogen flask on a nitrogen ball for protection, and need to be connected to the nitrogen ball.
