Filling the drying tubes
Note
Note the following rules:

Observe the filling heights indicated as exactly as possible.

The tube filling must not have any cavities. Therefore, tap the tube wall with a piece of wood or
cork when filling the tubes.
If the Sicapent® cannot be tapped properly, also a glass rod for slight compacting can be used.
Since the life time depends on the amount of Sicapent®, it is recommended to achieve a mean
density as high as possible. In doing so, make sure that the carrier gas flow will not be impaired.
