Bomb tube

Bomb tube empty (left), filled with reaction solution (middle) and closed (right).

Bomb tubes can be used as reaction vessels for carrying out chemical reactions under increased pressure. The manufacture and use of bomb tubes in chemistry goes back to Georg Ludwig Carius (1829–1875).

use

The thick-walled glass tubes, closed on one side, can be used for pressures of 10 to 20 bar overpressure. When filling the tube with the starting materials and, if necessary, the solvent, the upper end must not be contaminated or wetted. To melt the bomb tube, a glass rod, softened at the end in a gas flame, is used, which is attached to the opening of the tube, which has been softened by turning in the flame. Then the pipe is skillfully sealed with glass. The fused tube with the reaction mixture is then placed in a thick-walled iron protective cover, and finally heated in a bomb furnace. After the chemical reaction has ended, the bomb tube is allowed to cool down. Then you open the bomb tube at the melting point in order to purify and analyze the reaction solution .
