6.3 Functional test
The unit is to be assembled from dry, solvent-free glass
components.
Vacuum tightness
The apparatus is evacuated while flask is rotating. If there is a
pressure measuring device, it is determined whether the
vacuum remains constant in the system. For this purpose,
the vacuum tube between the vacuum source and the
pressure measuring device is interrupted by careful bending.
Pressure increase per minute should be less than 3 mbar.
Setting capability of rotation speed
The regulator for rotation speed is slowly turned from the
minimum setting to the maximum catch (clockwise). The motor
is to turn without interruption in each position of the regulator.
